The First Battle of Kyiv was the German name for the major battle that resulted in an encirclement of Soviet troops in the vicinity of Kyiv during World War II, the capital and most populous city of the Ukrainian Soviet Socialist Republic. This encirclement is the largest encirclement in the history of warfare by number of troops. The battle occurred from 7 July to 26 September 1941 as part of Operation Barbarossa, the Axis invasion of the Soviet Union.

Much of the Southwestern Front of the Red Army (commanded by Mikhail Kirponos) was encircled. Still, small groups of Red Army troops managed to escape the pocket in the days after the German panzers attacked east of the city, including the forces of Marshal Semyon Budyonny, Marshal Semyon Timoshenko and Commissar Nikita Khrushchev. Kirponos was trapped behind German lines and was killed while trying to break out.

The battle was an unprecedented defeat for the Red Army and was more damaging than the Battle of Białystok–Minsk of June–July 1941. The encirclement trapped 452,700 Soviet soldiers, 2,642 guns and mortars, and 64 tanks, of which only 15,000 soldiers escaped from the encirclement by 2 October. The Southwestern Front suffered 700,544 casualties, including 616,304 killed, captured, or missing during the battle. The 5th, 37th, 26th, 21st, and 38th armies, consisting of 43 divisions, were almost annihilated and the 40th Army suffered many losses. Like the Western Front before it, the Southwestern Front had to be recreated almost from scratch.

Despite being referred to as the "Battle of Kyiv," the city played a small and peripheral role in the overall battle. The battle took place over a large area in eastern Ukraine, with Kyiv being the focal point of Soviet defenses and German encirclement.

Adolf Hitler, the leader of the Third Reich, described the Battle of Kyiv as "the biggest battle in the history of the world", while Joseph Goebbels, the German minister of propaganda, called it "the greatest battle of annihilation of all time". Historian Evan Mawdsley described the battle as the Ostheer's "greatest triumph of the war in the East and the Red Army’s greatest single disaster", while historian Michael Jones dubbed the battle to be "the Wehrmacht’s greatest victory of the war".

Prelude

Plans and preparations

According to Barbarossa's operational plan, the Wehrmacht's Army Group South under the command of Field Marshal Gerd von Rundstedt was supposed to dominate the strategic area of Ukraine. This force planned to reach the Dnieper river in an enveloping movement by breaking the Soviet border defense and penetrating 650 kilometers deep into Soviet territory, and encircling the main forces of the Red Army in Ukraine west of the river.

Soviet High Command knew that the main focus of German forces in their invasion would be north of the Pripyat marshes, but Soviet leader Joseph Stalin insisted that the Soviet emphasis should be on the south. The Soviet Southwestern Front under the command of General Mikhail Kirponos in Ukraine was the most powerful front in the western borders of the Soviet Union, possessing a total of four field armies with the support of three mechanized corps in the front line, one mechanized corps in reserve and two mechanized corps in strategic reserve position.

In this situation, the Pripyat marshes separated the southern part of the operational area of the German forces from the northern part, and eliminated the possibility of receiving help for the army group south from other German units until after the Kyiv area. The operational area in Ukraine had a greater depth and width than the operational areas of the Wehrmacht's other two army groups, and as Kyiv was 600 km away from the borderline, it was considered a farther objective. These issues complicated the maneuvers of the southern Wehrmacht group.

June and July

After the start of Operation Barbarossa on 22 June 1941, Army Group South attacked Ukraine. The Red Army forces in this area put up a strong defense and despite a shortage of fuel and ammunition, they were ordered by the high command to carry out immediate counter-attacks. The 13th and 14th panzer divisions overcame this defense, and captured Lutsk on 26 June. Panzer Group 1 was the armored spearhead of Army Group South, and was thought to be to in an ideal position to advance towards Kyiv via Rivne. Meanwhile, Kirponos was trying to mount a concentrated counterattack. Commencement of his counter-attack on 26 June led to an armored battle of unprecedented scale between more than 2,000 tanks on a 70-kilometer front line. The inexperience of the Red Army officers in controlling the mass of armored forces, contributed to the failure of this counter-attack, and resulted in destruction of many Soviet reserves in the region. German forces also sustained heavy casualties however, and thus Army Group South lagged behind the rest of the advancing German forces.

On 30 June, Lvov was captured by the German 17th Army. On the same day, due to the ineffectiveness of earlier counter-attacks, Stavka ordered Kirponos to withdraw his forces to new defensive positions by 9 July, in the fortified areas of Korosten, Novgorod-Volynski and Letychiv along the 1939 Soviet-Polish border, known as the Stalin Line. Despite the delay in the advance of the German III Motorized Corps due to the Kirponos counterattack, by the arrival of the 11th Panzer Division at Berdichev on 7 July, the Stalin line was also broken and a gap was created between the Soviet 5th and 6th Armies south of Novgorod-Volynski.

With Kyiv under threat and the risk of the southwestern front splitting in half between the Soviet 5th Army in Kyiv and its 6th Army south of Berdychiv, Stavka ordered a new series of counter-attacks on the same day to destroy the enemy spearhead, stop the advance of the Germans towards Kyiv and maintain communication between these two armies. However, before these counterattacks began between 11 and 14 July, the capture of Zhytomyr by German forces on 8 July caused a weakness in Soviet defenses, whereby the German III Motorized Corps managed to break through the enemy's defensive line and open the road to Kyiv on 10 July. On the same day, the 13th Panzer Division of the III Motorized Corps created a defensive gap known as the "Zhytomyr Corridor" that reached the Irpen River, just 15 kilometers west of Kyiv. Red Army counterattacks again caused significant damage to the mobile forces of the Soviet Southwestern Front; such that only 7 BT and 25 T-26 tanks of the 9th Mechanized Corps, only 4 KV-1, 7 T-34 and 22 T-26 tanks of the 19th Mechanized Corps and only 2 BT and 28 T-26 tanks of the 22nd Mechanized Corps remained out of their initial strength.

Due to some parts of the German forces lagging 100 km behind, the decision of whether to attack Kyiv immediately was left to the higher levels of German command. At this time, Nikita Khrushchev, the political commissar of the Soviet Southwestern Front, was in charge of the Kyiv garrison, which included three rifle divisions, an airborne brigade, a tank regiment, some motorized forces of NKVD, students of the 1st Artillery College of Kyiv, two anti-tank battalions, and about 29,000 militiamen.

Debates over the attack on Kyiv

On 9 July, Army Group South command and the German Army High Command (OKH) re-emphasized the encirclement and destruction of the Soviet forces west of the Dnieper as the main objective of the operation. Seeing as the Soviet South-West Front was close to collapsing, capturing Kyiv was considered to be a secondary goal. At this time, Hitler did not want to assault Kyiv and prioritized the capture of a bridgehead on the Dnieper, subject to the destruction of large formations of Soviet forces west of the river. However, German Army senior commanders were still interested in capturing Kyiv. Repeated attacks by the forces of the Soviet 5th Army from the Pripyat region kept the German 6th Army occupied and unable to be used for this purpose. Rundstedt was confident that Kyiv would be captured by the III Motorized Corps in its rapid advance. Still, Hitler, after consulting with Field marshal Walter von Brauchitsch, commander in chief of the German army, felt that such a move would "unnecessarily sacrifice" panzer forces. Finally, at 1am on 10 July, Generaloberst Franz Halder, chief of the German army general staff, called the headquarters of the Army Group South and prohibited the use of panzer forces in the direction of Kyiv, except for reconnaissance and security purposes. By approving this order, Hitler made the III Motorized Corps only responsible for protection against attacks from the direction of Kyiv, and ordered them to avoid assaulting the city. He further pointed out that if the encirclement of the Soviet forces up to the southern Bug River were not achieved, the whole of the 1st Armored Group would advance towards Kyiv and the Dnieper River in the southeast.

Meanwhile, Rundstedt believed that with the retreat of many units of the Red Army to the east, it was no longer practical to encircle them up to the southern Bug River, and together with Halder, he wanted to encircle them around Bila Tserkva, west of the Dnieper River. Hitler expressed his consent to this, provided that the northern flank of Panzer Group 1 would be protected. Brauchich took advantage of the ambiguity of this order and concluded that the capture of Kyiv would secure the Panzer Group's northern flank but left the final decision to the commander of the Army Group South. Meanwhile, Rundstedt and Field marshal Walter von Reichenau, commander of the German 6th Army, who had previously supported the assault on Kyiv, now doubted it. Finally, Generaloberst Ewald von Kleist, commander of Panzer Group 1, was advised that if his offensive in coordination with the 6th Army provided a suitable opportunity to capture this city without the risk of being pushed back, then he was free to do so. Finally, the reconnaissance forces of the Wehrmacht determined on 13 July that the fortifications and concentration of the Soviet forces in Kyiv left no chance for a surprise attack.

Change in German strategy

In early July, after the end of the battle of Smolensk, German Army Group Center planned to attack Moscow from three axes, commencing in the beginning of September. The Soviet 5th Army held its previous positions in the Pripyat Marshes until mid-July, and this caused the creation of an additional front line of more than 250 kilometers in the open southern and northern flanks of the German army groups Center and South. In the face of this situation and following the strong resistance of the Soviet forces around Smolensk, German army High Command changed its strategy to continue the operation from mid-July. Hitler's directive No. 33 on 19 July, while criticizing the performance of the northern flank of the Army Group South against the Soviet 5th Army, mandated the German forces to "prevent escape of large amounts of enemy forces by crossing the Dnieper River deep into the Russian territories and destroy them". On this basis, the left wing of the Army Group South, in cooperation with the right wing of the Army Group Center, moved to destroy the Soviet 5th Army. Army Group Center continued its advance towards Moscow only with its infantry. Joint command was not established for the parts of both army groups that were to cooperate in the new operation.

Initial Soviet strategy

On 23 July, Stavka formed the Soviet Central Front under the command of General Fyodor Kuznetsov, consisting of the severely weakened 13th and 21st Armies, to protect the Gomel and the Sozh River regions on the southern flank of the German Army Group Center.

General Georgy Zhukov, the Chief of the General Staff of the Red Army, upon receiving information from the front line, concluded that the movement of the Army Group Center to the east had stopped and that the biggest strategic threat to the Soviet forces was in the Central front, where the movement of German mechanized forces to the south could cause the Soviet Southwestern Front to be in danger of being encircled. Zhukov told Stalin on 29 July that the success of any German advance toward Leningrad and Moscow seemed unlikely, but that the Gomel region was the Red Army's key strategic weakness. Therefore, Zhukov recommended that three armies, including one army from the strategic reserve and two armies from the western and Soviet southwestern fronts, and larger amounts of artillery, be assigned to the Soviet central front. He also recommended that Lt. Gen. Nikolai Vatutin be appointed as its commander. Stalin stated that the transfer of those forces would weaken the defenses of Moscow. In response, Zhukov stated that it was possible to transfer 9 fully equipped divisions from the Far East within two weeks to strengthen these defenses, but Stalin expressed concern that the Far East would be vulnerable to Japanese attack. Zhukov suggested that the Soviet Southwestern Front be pulled back behind the Dnieper River. When Stalin asked about the fate of Kyiv in this case, Zhukov stated that it could be abandoned. Stalin became upset and rebuked Zhukov in a harsh tone and called his words "worthless". He stated his intention was to preserve Kyiv at all costs, like Leningrad. Zhukov told Stalin that if he thought the Chief of the General Staff was talking "nonsense", he would be dismissed and sent to the front line. Stalin agreed to this request and appointed Marshal Boris Shaposhnikov to replace Zhukov as the chief of the Red Army General Staff, and for Zhukov to command the Soviet reserve front.

Continuation of Army Group South's advance

Despite the stubborn resistance of the Red Army forces and unexpectedly heavy rain, the German 17th Army managed to break through in the Vinnytsia region, and its 11th Army advanced to the Dniester River. Panzer Group 1 was able to reach the Dnieper River and create a bridgehead on it south of Kyiv. On 28 July, Stavka ordered the Soviet Southwestern and Southern Fronts to disrupt the German offensive, and prevent more of them from reaching the Dnieper River. In response, the Soviet Southwestern Front had to re-organize its forces and prepare to attack towards Radomyshl and Zhitomir to connect with the Soviet Southern Front. However, Germans completed their encirclement of Soviet forces in Uman region on 4 August, trapping the Soviet 6th and 12th Armies in it. Stavka reorganised troops; the Soviet Fifth Army received the 1st Airborne Corps, the 15th and 31st Rifle Corps, and the 9th and 22nd Mechanized Corps, and was ordered to attack the same day. The counterattack of the Soviet Fifth Army was stopped on 8 August with little gains and heavy casualties. On the same day, Korosten, 150 kilometers northwest of Kyiv, was captured by the German XVII Army Corps, forcing the Soviet 5th Army to retreat towards Kyiv.

On 4 August, Stavka placed the 38th Soviet Army and the 8th Mechanized Corps under the command of Lieutenant General Dmitry Ryabyshev, and ordered all available units in the Cherkasy region to cover the gap created as a result of the loss of the Uman region armies. This army had a total strength of 40,000 troops in form of five rifle and four cavalry divisions, which had mostly recently arrived in the region, and were tasked to defend a 200 km front line. Stavka also formed the Soviet 37th Army under Major General Andrey Vlasov six days later, after the Soviet 6th and 12th Armies were officially disbanded, and stationed it on the line of the Dnieper River between Kyiv and Kremenchuk.

The most advanced elements of the German 6th Army reached the outskirts of Kyiv on 6 August, but were stopped by the Soviet 37th Army. Two days later, the German 6th Army was forced to take a defensive position and was pushed back from some positions by the Soviet 37th Army's counterattack from 12 August. On the same day, Hitler ordered Rundstedt to stop the assault on Kyiv.

Operation Barbarossa, 22 June to 25 August 1941

Rundstedt issued his Order No. 5 on 10 August, ordering his forces to capture the west bank of the Dnieper River. As part of this operation, Nikolaev was captured by Germans on 16 August, and the SS panzer division Leibstandarte SS Adolf Hitler reached Kherson on 19 August. Meanwhile, the German 22nd Infantry Division of the III Army Corps captured a 650-metre bridge over the Dnieper in Breslav for the 11th Army, the 9th Panzer Division secured a crossing over the Dnieper in Zaporozhye, and the 13th Panzer Division captured a 900-meter bridge in Dnipropetrovsk on 25 August. On the next day, the German 60th Motorized Infantry Division reinforced this bridgehead, and were joined within a week by the 198th Infantry Division and SS Viking division. The heavy counterattacks of the Red Army in this position targeted the Germans from three sides, but the Wehrmacht forces with the support of the Luftwaffe aircraft, including the 22nd Italian fighter group, repelled them. Rundstedt tried to create another bridgehead in Cherkasy to reduce the pressure on the previous bridgeheads. When this succeeded, marshal Semyon Budyonny, commander of the Soviet Southwestern Direction, counter-attacked against Cherkasy.

Army Group Center's advance to the south

According to the 29 July report, out of the initial 953 tanks of the Army Group Center's Panzer Group 2 at the beginning of the operation, only 263 tanks remained serviceable as of 25 July. This unit also lost about 20,000 men out of its initial strength of 113,000 troops up to this time, while receiving only 10,000 soldiers as replacements. Therefore, Generaloberst Heinz Guderian, commander of the Panzer Group 2 in the right (southern) flank of the Army Group Center, Informed the Army Group commander that his units would not be ready to undertake any new operations before 5 August. Facing a high number of enemy forces and logistical problems, on 30 July, the Hitler directive No. 34 asked Army Group Center to pull its two Panzer Groups away from the front line to rebuilt and refit in order to transfer them to the flanks, while also taking a defensive posture in the best positions along with limited offensive operations. The purpose of such orders was to focus the German advance on Leningrad in the north and Kyiv and Ukraine in the south. The movement of Army Group Center to the south created a possibility that, considering the battlefield conditions and the bulge on the front line, a very large encirclement would be created if the Red Army forces did not evacuate the bulge in time.

Due to the German Army High Command emphasis on Moscow, in order to preserve the necessary resources for the future advance to the east, the number of units initially assigned to the Panzer Group 2 for the new operation was limited. By Halder's order, despite Guderian's opposition and protest, only units of the Panzer Group 2 were to be used, which "are not needed in other missions of the Army Group Center and have enough readiness and mobility for combat". In order to counter the Soviet 5th Army, Halder ordered the capture of the parts of Gomel and Chernigov that could be reached.

By the beginning of the execution of Hitler's directive No. 34 on 6 August by the Central Army Group, the German Second Army and the XXIV Motorized Corps of the Panzer Group 2 attacked in the direction of Gomel in the south by crossing the Suzh River. Guderian's forces, along with air support of the 3rd and 53rd bomber, 210th heavy fighter and 51st fighters wings, pushed back the 21st Army of the Soviet Central Front to the south, threatening Red Army front line by creating a gap between its southern front around Kyiv and the units of the western and reserve fronts east of Smolensk. On 14 August, Stavka tried to block the Germans advance by filling the gap between the Western and Reserve Fronts and the weak Soviet Central Front. He did so by forming Bryansk Front under the command of Lieutenant General Andrey Yeryomenko with Soviet 3rd and 13th Armies and the newly formed 50th Army. This front, with a total of fifteen rifle divisions, three cavalry divisions, one tank division and one airborne corps, was tasked with covering a front line of 230 kilometers from south of Roslavl in the north to Novgorod-Sversky in the south.

Colonel General Fyodor Kuznetsov, the commander of the Soviet Central Front, decided to abandon Gomel on 15 August. The Soviet rearguard left behind to protect the retreat of the rest of the Central Front forces caused resistance for the Germans in Gomel. On 16 August, Bock ordered the German Second Army to leave only the necessary forces in the Zhlobin area and with the rest of its forces to attack Gomel in the south. However, the resistance and attacks of the Red Army in the Gomel region on the same day stopped the advance of the XLIII and XIII Army Corps of the German 2nd Army to the south. In order to prevent the escape of Soviet forces from the Gomel area, Guderian ordered the XXIV Motorized Corps to Starodub, 120 km east of Gomel. The road junction in Meglin, 60 kilometers north of Starodub, was captured by the 3rd Panzer Division of this corps on 16 August. The next day, despite enduring heavy pressure from the west, the German 10th motorized infantry and 3rd Panzer divisions captured and destroyed a section of the Gomel-Bryansk railway.

Guderian's Panzer forces and the infantry of the Second Army occupied Pochep, 60 km northeast of Starodub, and reached the outskirts of Gomel and Starodub by 18 August, in order to sever the connection between the Soviet 13th and 21st armies and cause a break between the Soviet central and reserve fronts. On the same day, Stavka formed the Soviet 40th Army under the command of Major General Kuzma Podlas, as part of the Southwestern Front, specifically to block Guderian's advance. This force was weakened however, only consisting of two rifle divisions and an airborne corps, which were severely weakened by the previous battles in Dnieper River area. On 19 August, some units of the 3rd Panzer Division were surrounded by Red Army forces near Oncha, 30 kilometers north of Starodub. As the situation became serious, some forward forces of the 3rd Panzer Division returned to Oncha by fleeing from Starodub. Despite the settlement of the situation in Oncha, the infantry of the German 2nd Army was still far away from this place due to the clashes in the Zhlobin area, and the Red Army still blocked the Meglin-Oncha road.

The Wehrmacht's supply lines were unable to keep up with the advance of Panzer forces on the bad roads of the region. The poor mechanical condition of the Panzer Divisions and the proneness of their tanks to break down became further obstacles to Guderian's advance. Thus, during this period, despite the order of the German Army High Command to XXIV Motorized Corps to advance towards Gomel from the east, this unit was unable to do so. The lack of coordination between the different German divisions created a difficult situation for the Germans in the Gomel region. The diaries of the logistics officer of 3rd Panzer Division on 18 August stated: "The advance of the division is so rapid that the [supply] columns are unable to keep themselves coordinated." The supply columns of the XXIV Motorized Corps were moving at an average speed of only 12 kilometers per hour during this advance. The next day, the lack of fuel forced Generel der Panzertruppen Leo Geyr von Schwepenburg, the commander of the XXIV Motorized Corps, to inform Guderian's headquarters that the capture of Novozibkov, 70 kilometers east of Gomel, was not feasible. Guderian, in turn, reported this issue to Bock. In addition to the fuel issue, the lack of spare parts brought the number of operational tanks of the 4th Panzer Division to only 44, and on 22 August in 3rd Panzer Division to only 60 tanks. Finally, on 21 August, the fuel needs of the XXIV Motorized Corps were re-supplied with air transport, and Starodub was captured on 22 August.

The final German attack on Gomel began on 19 August with XIII Army Corps attacking it from the northwest and northeast. The 17th infantry division penetrated into the city from the west and north, leading to intense house-to-house clashes. By evening, the Red Army troops were pushed to the southern part of the city, where they attempted to destroy all the bridges over the Sozh River in the city. The fighting continued for another day in Gomel. Despite the strong resistance of the Soviet 21st Army, Panzer Group 2 and the German 2nd Army completely captured Gomel by 21 August. The clearing of the city of remaining Red Army elements was done by the German 131st Infantry Division. A third of the Soviet defenders of Gomel were encircled by Germans and defeated. About 50,000 soldiers of the Red Army were captured by the Germans in this position. After the capture of Gomel, the Soviet 5th Army, enduring heavy pressure in its northern flank from the German 2nd Army, began to retreat eastward from the area north of Mosir, southwest of the Pripyat Marshes.

Guderian's entry into Ukraine

On 21 August, Hitler ordered the German 2nd Army and Panzer Group 2 to advance to the south, deeper into Ukraine. However, on 23 August, the German Army High Command, in planning to pursue a simultaneous offensive towards the south and Moscow, split Panzer Group 2 and ordered XLVIII Motorized Corps to remain in the Smolensk region as a mobile reserve. On the same day, Guderian, without knowing about such an order, in his meeting with Hitler in Wolfschanze, had the promise that his Panzer group would remain united reaffirmed. The next day, Guderian learned about the order from High Command and immediately requested the return of the corps, which was scheduled to join the German 4th Army. However Guderian's protest was turned down by Bock. Panzer Group 2 resumed its advance to the south on 25 August, attacking the Soviet central front through Gomel and Starodub, driving it back in disarray towards the Desna River.

Desna River was considered a major natural obstacle in front of Guderian's forces on their way to entering Ukraine. On 25 August, the 3rd Panzer Division reached Novgorod-Sversky on the bank of this river. Panzer Group 2 initially received reports about the destruction of a vital bridge across the Desna. However, it was revealed that the 800-meter bridge was captured intact by the 3rd Panzer Division on the morning of 26 August. Guderian called this news "surprising and the most pleasant". After this success, 3rd Panzer Division expanded its front eight kilometers beyond the river to protect the bridgehead. The next day, Soviet forces attempted to take back the eastern bank of the river and destroy its bridge. The German front was pushed back, but the Germans eventually repulsed the attacks. The German 10th Motorized Infantry Division also captured another crossing on the Desna River near Kurup, 50 km southwest of Novgorod-Sversky. On 30 August, this division tried to continue advancing south alone, but directly contacted Yeryomenko's offensive frontline and was repulsed. According to diaries of Bock and Guderian, this division was unable to protect its bridgehead south of the Desna river under the attack of four enemy divisions. This assault weakened the 3rd Panzer Division and the 10th Motorized Infantry Division of the XXIV Motorized Corps to such an extent that these two divisions took a defensive position for a while.

By the end of August, the Soviet Southwestern Front, consisting of more than 50 divisions in 6 armies, was in a triangular formation with its apex west of Kyiv at a depth of 500 km. The long flanks of this front were attacked from the north by the German Panzer Armored Group 2 and the 2nd Army, from the west by the German 6th Army, and from the south by the German Panzer Group 1 and the 17th Army. Even before the start of the new German operation, the Soviet Southwestern front was in a precarious position and already semi-encircled. The most powerful formations of Kirponos, being deployed in the western areas, were not facing the danger of the German Panzer forces on the outer flanks. Kirponos was aware of these conditions, but the approach of the Soviet High Command did not allow him to take effective action.

After Budyonny and Kirponos's repeated requests to Stavka to withdraw the Soviet 5th Army to shorter lines, and the Soviet High Command's agreement to that on 19 August, German forces crossed the Dnieper to the east on 23 August. The command of the German 6th Army did not expect the withdrawal of the Soviet 5th Army until 18 August. Halder and the command of the Army Group South ordered to quickly pursue these Soviet forces. Bad roads in the area delayed the German 6th Army. The Soviet 5th Army was not able to destroy the wooden bridge over the Dnieper behind itself, and the bridge was assaulted by LI Army Corps of the German 6th Army and 11th Panzer Division forces, leading to its capture. Kirponos ordered all air assets at his disposal to destroy the bridge, and Soviet Il-2 aircraft destroyed the bridge with incendiary bombs, cutting off the German troops who had crossed the Dnieper River form behind. These forces were isolated from other German units in the marshes between the Dnieper and Desna for ten days until the German engineers repaired the bridge by 2 September.

On 26 August, the XVII Army Corps of the German 6th Army in the northern flank of the Army Group South captured Chernobyl, 110 km north of Kyiv. On 1 September, Generalleutnant Georg von Sudenstern, the Chief of Staff of Army Group South, communicated with the Army Group Center's 2nd Army in order to coordinate his left wing. He stated that due to the lack of equipment required to cross the river, the 6th Army of the Army Group South is dependent on the help of the German 2nd Army to do so.

Due to a lack of supplies, the motorized corps of Panzer Group 1 rested and rebuilt for several days from 27 to 28 August. Meanwhile, the XXIV Motorized Corps, as Guderian's armored spearhead in the northern part of the Wehrmacht operation in the Kyiv region, began a new operation on 25 August. However, due to the difficult geographical conditions east of the Dnieper River and north of Kyiv, Rundstedt was worried about the escape of the Soviet forces to the east. The strong resistance of the Soviet 5th Army and the logistical problems of the German 2nd and 6th Armies intensified this concern. On 28 and 29 August, he ordered Panzer Group 1 and the 6th and 17th armies to cross the Dnieper River in as many places as possible. On 1 September, Panzer Group 1 received an order to end their period of rebuilding and return to the front line. This meant that the command of Army Group South decided to use its worn-out forces with "the last of their remaining strength" and without rest.

The LII Army Corps of the German 17th Army seized a crossing on the Dnieper in Drifka, south of Kremenchuk, 280 kilometers southeast of Kyiv, on 31 August. The Panzer forces of Army Group South expanded this bridgehead by reinforcing it on 4 September. Facing this danger, Marshal Budyonny immediately ordered the Soviet 38th Army under the command of Major General Feklenko, to destroy the German forces that had crossed the river. However, this army was too weak to do so, and its planned counterattack for 8 September was not executed.

The intensification of the Soviet resistance, and the knowledge that the Red Army was redistributing its best troops, caused the Germans to change their assessment of the situation after the end of August, and made it clear that Stalin had ordered Soviet forces to preserve the Dnieper river line. Initially, Rundstedt planned to send the 17th Army towards Guderian to the north through the Kremenchuk bridgehead, so the 1st Panzer Group would attack through the Dnipropetrovsk bridgehead to the east. Accordingly, on 4 September, Army Group South ordered the 17th Army to attack the Mirgorod-Lubny general line in order to encircle the enemy forces in the Middle Dnieper region and Kyiv. Panzer Group 1 was to cover the right flank of this movement by advancing towards Poltava via Krasnograd in a northerly direction. After a meeting on 8 September at the headquarters of Army Group South in presence of Brauchich and Halder, it was decided to reverse the roles of the 17th Army and the Panzer Group 1. The purpose of this change was to complete the encirclement of the enemy as quickly as possible.

In addition, it was decided that the Panzer Group 1 would advance to Romny, 200 km to the north, and hold a 100 km line from Lubny in the south in order to block the path of possible strong enemy attacks from this area to open an escape route. Four infantry divisions of the 17th Army were also ordered to hold the rest of the encirclement ring from Lubny to the south, while its other six infantry divisions were to move towards Kharkov in the east. The start date of the new operation was set on 11 September. Before Halder left the meeting, Rundstedt asked him to put Panzer Group 2 and the 2nd Army under his command in order to create unity in the command of operations in the Kyiv area, which was rejected.

The V Air Corps Luftwaffe was deployed to new bases in Kirovgrad and Uman to provide air support to Army Group South. The LII, LV and parts of the XI Army Corps of the German 17th Army crossed the Dnieper in the center of the front line of the Southern Army Group on 10 September. Panzer Group 1, led by the forces of Major-General Hans-Valentin Hube in the 16th Panzer Division of XLVIII Motorized Corps, began crossing the Dnieper on 11 September. By 12 September, Army Group South concentrated 20 divisions in this area against 5 rifle and 4 cavalry divisions of the 38th Army in the southern flank of the Soviet southwestern front. Rain, muddy roads, logistical problems and local counter-attacks of the Red Army delayed the advance of the Army Group South to some extent. 16th Panzer Division was used as the armored spearhead of the XLVIII Motorized Corps and initially achieved success, but after running out of fuel, stopped to resupply. At this time, Panzer Group 1 had a total of 331 tanks, which was equivalent to 53% of its initial strength on 22 June. After collecting the necessary supplies and building a suitable bridge, XLVIII Motorized Corps under the command of Lieutenant General Werner Kempf, resumed the attack.

Soviet counter-attacks on the Bryansk front

Beyond the losses inflicted to the Red Army as a result of the Army Group Center actions in the northern (Velikye Luki area) and southern (Roslavl, Krychev, Zhlobin, and then Gomel) flanks, Soviet command believed these attacks were merely tactical measures to divert attention or resources from the vital Smolensk-Moscow axis. Until this time, the Soviet senior commanders thought that Guderian's movement to the south objective was attacking to Bryansk and then Moscow. Therefore, the Bryansk Front was generally responsible for defending the Moscow axis from the southwest and was not responsible for preventing the penetration of the Panzer Group 2 in the northern flank of the Soviet Southwestern Front. Moreover, by keeping troops in the Kyiv area, the Soviet High Command hoped to use them against the southern flank of Army Group Center as it advanced towards Moscow.

However, contrary to the expectations of the Red Army, Guderian continued to attack to the south with little resistance, taking the Soviets by surprise. However, Stalin still insisted that Kirponos should continue to defend Kyiv at any cost and believed that the Bryansk front, in addition to protecting the Bryansk axis, was also capable of defeating the enemy forces that were threatening the northern and southwestern fronts, and destroying them as well. Stalin refused to order an all-out attack by the Bryansk front against Guderian's eastern flank in order to preserve the forces of the front to stop the future advance of Army Group Center towards Moscow.

The Western Front was under the command of General Semyon Timoshenko, the Reserve Front under the command of General Zhukov, and the Bryansk Front under the command of General Yeryomenko. On 25 August, Stavka ordered them to carry out concentrated counter-attacks in the Smolensk-Yelnia-Novozibkov axis to repel Guderian's invasion, and in the process to confront the entirety of Army Group Center. Accordingly, after the dissolution of the Soviet Central Front and addition of the Soviet 21st Army under its command, the Bryansk Front was ordered to defeat the Panzer Group 2 by conducting a direct attack and to bolster the strong defense of the north of Kyiv. This operation was to take place on a very wide front line from Zhukovka in the north to Yampol in the south. On 26 August, Stavka asked the Bryansk front to encircle and destroy Guderian's forces in Starodub, and bring the flanks of the Soviet 13th and 21st armies closer to each other. This order was issued while the assembly of the Bryansk Front was not yet completed, and its implementation would cause the use of the Red Army forces piecemeal. There was also a large gap between the main part of the Bryansk Front and the reinforcements from the former Central Front, and only the Soviet 50th Army was fresh and capable of sustained offensive operations. Stavka insisted on continuing these counterattacks despite these problems. False information led the Red Army to believe that the Germans were planning to inflict a heavy blow on the right (north) flank of the Bryansk front. Therefore, Shaposhnikov ordered Yeryomenko to reinforce this part with the 50th Army. This action caused this army to move from the threatened area to an area where there was no danger, and the counterattack of the Bryansk front was greatly weakened at a vital point.

After the failure of the first counterattack of the Bryansk Front, on 28 August, Stavka ordered a massive air attack by 450 aircraft of the Bryansk Front with at least 100 DB-3 bombers against the German tanks. Between 29 August and 4 September, Soviet aircraft made more than 4,000 sorties against Panzer Group 2. Despite Yeryomenko's post-war claims that this massive air offensive was "very effective", these Soviet air attacks had little effect on Guderian's advance. During these attacks, 55 Soviet aircraft were shot down, and 57 other aircraft were destroyed by German attacks on eight Soviet air bases. Following this inconclusive air operation, two days later Stavka again ordered the whole Bryansk Front to launch another counterattack towards Roslavl and Starodub, and destroy Guderian's forces at Pochep, Novgorod-Sversky and Novozibkov, and subsequently further advance to reach the Petrovich-Klimovichi-Schers line by 15 September. Yeryomenko ordered the counteroffensive to begin on 2 September. The two shock groups of the Bryansk front operated in two axes with a distance of 140 kilometers between them.

Soviet Bryansk Front counterattack against the eastern flank of the Panzer Group, known as the Roslavl-Novozibkov Offensive operation, did not gain much.

Elsewhere, the Soviet 108th Tank Division attacked on 30 August with more than 90 tanks, including a large number of KV-1 heavy tanks on which the usual German anti-tank weapons did not work, against the 17th Panzer Division of XLVII Motorized Corps in the eastern flank of Guderian. This attack created a 2-kilometer breach in the German lines and raised the concern of splitting this German corps in half. The 17th Panzer Division's counterattack next day was ineffective due to the superiority of the Red Army tanks, and resulted in the loss of 11 German tanks. On 1 September, the counterattack of the 18th Panzer Division, another division of XLVII Motorized Corps, also collided with the Soviet 4th Cavalry Division, which was in the area in support of its tank division. Finally, with the fire concentration from two Panzer divisions and the air support of the II Air Corps of the Luftwaffe, the attack of Yeryomenko's tanks was repelled after causing great damage to both sides.

Due to the confusing operational conditions, the reorganization of the Bryansk front faced many supply problems which were not resolved until the beginning of the operation. Therefore, Yeryomenko asked for the postponement of the counterattack until 3 September, which was agreed to by Soviet Command. However, under pressure from Stavka, Yeryomenko was again forced to launch the counterattack on 2 September. After two hours of artillery shelling, both shock groups directly attacked Guderian's advance forces. Inadequate air support, uncoordinated attacks and other factors caused this counterattack of the Bryansk front to fail, with the XLVII Motorized Corps repelling these counterattacks. During these clashes, the armored forces of the Soviet Bryansk Front were destroyed, and Guderian's tanks continued to move south.

Discussion about continuation of the Wehrmacht operation

On 26 August, Guderian asked again the German Army High Command to release the XLVI Motorized Corps, but was once again rejected. On 27 August, during a visit of Major General Friedrich Paulus, Quartermeister of OKH, to the headquarters of the Panzer Group 2, Guderian again requested to receive more reinforcements. Guderian stated that the German 2nd Army, advancing towards the southwest, was in an operationally diverging course from Panzer Group 2, and was now separated from the right wing of the XXIV Motorized Corps, which created a 75 km gap between them. He considered the left (eastern) wing of the XXIV Motorized Corps to be similarly insecure. Guderian proposed a solution; transferring the XIII and XLIII Corps as well as the 1st Cavalry Division from the 2nd Army to his command. Guderian also repeated his request for the return of the XLVI motorized corps, and Paulus agreed to support these requests. On the same day, Guderian contacted General-Major Hans von Greifenberg, the Chief of Staff of Army Group Center, and made a similar request for reinforcements. Considering the pressure exerted on the long defensive line of the Army Group Center and its need to have a mobile reserve, Bock, in consultation with Halder, initially agreed only to move the 1st Cavalry Division closer to the right flank of the XXIV Motorized Corps. When Guderian insisted on his demands again on 29 August, Bock rejected Guderian's request, stating that the XXIV Motorized Corps had informed the 2nd Army that it did not consider there to be a threat on its right flank. However, Bock agreed for the Grossdeutschland infantry regiment to be transferred to Guderian on the next day.

On 30 August, the Operations department of the German Army General staff ordered Army Group Center to prepare to place the divisions of the 2nd Army under the command of Panzer Group 2 after the 2nd Army crossed on Desna river, "in order to continue operations with the Army Group South". The headquarters and "parts of the 2nd Army that are not needed in the continuation of operations south of the Desna River" remained at the disposal of the Army Group Center. The number of these "required divisions" depended on the demands of Army Group South, placing them at the forefront of decision-making.

In the meantime, the issue of continuing the advance to the east towards Moscow was intensively discussed by German high command. A plan was formed that Panzer Group 2 and the 2nd Army would stop at the Nagin-Konotop railway, before completing the encirclement of the Soviet Southwestern Front, and then rush eastward with the rest of Army Group Center. In this regard, after being informed about the Army General staff directive, Hitler informed Brauchitsch on 30 August that the strength of the Army Group Center around Desna River should not be used for operations in Ukraine, but must be prepared to be used to advance towards Moscow. Bock, who had initially wanted to continue advance towards Moscow, now saw operational opportunities in the south, and so was opposed to this plan. He considered Guderian's movement as irreversible, and strongly desired to complete the offensive to the south, to avoid a time-consuming and costly redeployment of forces. Hitler decided to allow Guderian to continue south and connect to the Panzer Group 1.

Continuation of Guderian's advance

At this time, while the XLVII Motorized Corps was solely responsible for protecting the long left (eastern) flank of the Panzer Group 2, only 86 operational tanks were left for XXIV Motorized Corps as Guderian's armored spearhead. This was equivalent to less than half of the tanks of the 3rd Panzer Division at the beginning of the Barbarossa operation. Only the 4th Panzer division of this corps was capable of offensive operations at the time. Therefore, that same evening, Bock reluctantly agreed to send the SS Panzer Division Das Reich to Guderian. According to Bock, in a report on 2 September, Guderian described the situation of the Panzer Group 2 so pessimistic that the commander of the army group proposed to get permission for the tactical withdrawal of Guderian's forces from OKH, so that these forces could support the German 2nd army on their left flank. Guderian immediately rejected this proposal and used the opportunity to insist on his previous request for reinforcements. Finally, under the influence of Guderian's report, Bock agreed to release the XLVI Motorized Corps on 2 September.

After four days of halting their armored spearhead at the Desna river crossing and receiving sufficient supplies, the advance of the Panzer Group 2 to the south was resumed on 31 August. Guderian's offensive pushed aside the Bryansk front and put the Soviet 180th tank division in a semi-encirclement situation at the end of 2 September, while also dealing a heavy blow to its 4th cavalry division. Until 6 September, the mobile forces of the Bryansk front were surrounded and fighting for their survival. Guderian's forces had captured around 30,000 Soviet forces prior to the tenth day of their advance in Ukraine.

Following this, Stalin severely criticized Yeryomenko, and ordered him to pull his troops out of the encirclement if possible, and to use any available air forces even in bad weather. At this time, only 16 tanks and 5 armored vehicles were available for the Soviet 108th tank division, and only 38 tanks were left in the 141 tank brigade. Yeryomenko tried desperate measures to free his troops, including the use of roadblocking units that opened fire on his own forces that were retreating without permission, but was unsuccessful.

In a report to Stalin on 4 September, Budyonny described the threat to his flanks and requested immediate reinforcements. In the absence of this possibility, Budyonny requested permission to create a reserve force for himself by transferring four divisions from the 37th and 26th armies of the Western Front. At Stalin's behest, Shaposhnikov rejected both of Budyonny's requests. On 6 September, when the Soviet 21st Army was placed under the command of the Southwest Front, Kirponos ordered this army to attack the rear of the 3rd and 4th Panzer Divisions XXIV Motorized Corps from the west. The actions of Kirponos did not affect the movement of Guderian's armored forces and they crossed the Saim river the next day. Faced with a dangerous situation, on 7 September, Kirponos asked for permission to withdraw his forces north of Kyiv to the eastern side of the Desna River. After the fall of Chernigov On 8 September to German 2nd Army, Shaposhnikov informed the Southwestern Front on 9 September that the High Command had decided to withdraw the Fifth Army and the right wing of the Soviet 37th Army to the east of the Desna River, in order to take a distance from the German Sixth Army and rotate its front line to the north, facing the advance of the Panzer Group 2.

Sacrifice of the Soviet Southwestern Front

The Soviet Southwestern Front was defending a front line of more than 800 kilometers. On 11 September, Budyonny sent a telegram to Stalin stating that only powerful forces would be able to prevent the encirclement of this front, which the southwestern front currently lacked. He stated that if the Soviet high command did not provide the necessary reserve forces in this area, it would be necessary to pull back the southwestern front, and any delay in this matter would only cause loss of its forces and the destruction of a large number of supply units. Budyonny also requested permission to withdraw 250 kilometers eastward from the Dnieper River to the Pasel River. However, Stalin again ordered Kirponos not to abandon Kyiv without Stavka's permission and not to destroy the bridges. Stalin believed that if the Southwestern Front retreated from the Dnieper River line, the Germans would quickly gain a foothold on its eastern bank. As a result, the southwest front would be under the pressure of the enemy from three directions instead of two when retreating. In addition, if the Germans moved in a coordinated fashion, the Soviets would be surrounded, as it would not be possible to withdraw all 667,000 troops to behind the Pasel River. He considered the encirclement of the 6th and 12th Soviet armies in Uman as the consequence of attempting such a retreat, and that it should not be repeated. Stalin also did not consider the defenses on the Pasel River ready to use.

On 13 September, at the suggestion of Zhukov and by order of Stalin, Stavka replaced Budyonny with Marshal Semyon Timoshenko in command of the Soviet Southwestern direction without issuing a withdrawal authorization. Timoshenko, believing that reinforcements were on the way and the Bryansk Front's counteroffensive would have good results, agreed for the Southwestern Front not to retreat. However, only one rifle division and two tank brigades with 100 tanks were provided to him, and it became clear that the Bryansk front lacked vital strength, with only 20 operational tanks in all its tank brigades.

Completion of the encirclement

On 12 September, by transferring tank units from the 55th Army to the 13th Army, Stavka changed the attack plan of the Bryansk Front, and ordered Yeryomenko to stop his offensive along the Roslavl axis. Reorganizing his forces, he ordered for Guderian's left wing to be targeted again to cover the created gap by the 18 September offensive, and to connect with the units of the southwestern front. To encourage Yeryomenko, Stavka promoted him to the rank of Colonel General and assigned some reinforcements to the disorganized Bryansk Front. After being delayed due to rain, the 16th Panzer Division of Army Group Center moved 20 kilometers from the Dnieper River bridgehead to the north, defeating the Soviet 297th Rifle Division. They reached Khorol, 230 kilometers southeast of Kyiv, by evening. The division captured the headquarters of the Soviet 38th Army, but Feklenko, the commander of this army, managed to escape. The next day, 14th Panzer Division of Army Group Center reached Lubni, 30 kilometers north of Khorol. By attacking the supply lines of the Soviet Southwest Front, this division captured 1,500 soldiers, 600 trucks, 70 cannons, and 3 aircraft. The 9th Panzer Division was close behind the 16th and 14th divisions. These attacks by Kleist's forces in the Panzer Group 1 created a gap of 20 kilometers between the Soviet 38th and 6th Armies, and placed them only 40 kilometers away from Generalmajor Walther Model's forces in the 3rd Panzer Division of the Army Group Center in the north. At the same time, the resistance of the Red Army forces was increasing and a fierce air battle was underway. The 16th Panzer Division met the stubborn resistance of the NKVD elements in Lubny, and the advance of 3rd Panzer Division from Romny lasted two days. These problems caused the German Army High Command plan to connect two Panzer groups to one another on 13 September not to be realized.

A small battle group from the 3rd Panzer Division, consisting of three tanks, eight armored reconnaissance vehicles, six artillery pieces, and an anti-tank company, advanced southward and captured the city of Lukhvitsa and its bridge over the Sula River. Due to the lack of strength in this location, Guderian requested that infantry take place of the 18th Panzer Division, which was currently was holding a 90-kilometer line, in the northern part of his eastern flank, so that the Panzer division could move towards Romny. The command of the army group opposed this request due to the distance of this division from the intended target, and wanting to suffer minimum attrition before the upcoming attack against Moscow.

In the early morning of 14 September, Major General Vasily Tupikov, the Chief of Staff of the Soviet Southwestern Front, sent a personal telegram to Shaposhnikov that stated: "The disaster has begun and will show itself to you in a few days". In a sharp response, Shaposhnikov described Tupikov as "panicky" and called for "calmness and not to yield to panic" at all levels of command and to stop the retreat of the Soviet 21st and 5th Armies. He asked the forces of the Soviet Southwestern Front "not look backwards" and to "fulfil comrade Stalin's order of September ll". On 15 September, under pressure, Timoshenko completely reversed his previous opinion and told Shaposhnikov in Moscow that he wanted the immediate withdrawal of the Soviet Southwestern Front. Meanwhile, with the pressure of the German 6th and 2nd armies, the northern wing of the Soviet southwestern front was gradually collapsing. The German 17th army also slowly began to advance from the Kremenchuk bridgehead to the north. The XI Army Corps of the German 17th Army with three infantry divisions was placed under the command of the Panzer Group 1 on 13 September, to ensure the protection of the eastern flank of the encirclement that was being completed.

At 18:00 on 14 September, a small battle group of the 18th Panzer Division reached an engineer company of the 16th Panzer Division north of Lubny. However, this meeting between the first vanguard elements of the northern and southern pincers was symbolic, and there was still a relatively large space between the body of the two pincers. The next day, more units of the 9th Panzer Division continued moving north to establish a stronger connection. On 16 September, with the complete connection of the 3rd and 16th Panzer Divisions, the armored spearheads of the Panzer Groups 1 and 2, in the south of Lukhvitsa, the encirclement ring was completed 120 kilometers southeast of Kyiv, such that all the Soviet Southwestern Front, including the five Armies, 5th, 21st, 26th, 37th and 38th, were trapped inside it. The encirclement ring was formed on the eastern side by Panzer groups 1 and 2, and on the western side by the German 2nd and 6th armies. The encirclement included a large region with an area of approximately 20,000 square kilometers, 200 kilometers from the connection point of the Wehrmacht's Panzer forces to the city of Kyiv, east to west.

Attempted Soviet retreat

On 16 September in Poltava, in a meeting with General Bagramian, the chief of operations of the Southwestern Front, Timoshenko stated that when the encirclement ring of the Germans is not yet tight, a decision should be made without delay to allow the Southwestern Front to retreat. Timoshenko stated that the High Command will eventually make this decision, but there is no time to waste in receiving confirmation from Moscow. According to Bagramian's memoirs, taking into account the tone of Shaposhnikov's previous telegram, Timoshenko himself deeply doubted the truth of this opinion. Timoshenko ordered Bagramian to fly to Priyatin and verbally order Kirponos to "abandon the Kyiv fortification area and, leaving the covering forces on the Dnieper River, immediately begin withdrawing the main body of forces to the defensive rear line (the Psel River)." Kirponos was also ordered to carry out counter-attacks in Lubny and Rumny areas to slow down the Panzers as much as possible. Timoshenko, who did not have the authority to issue such an order contrary to Stalin's wishes, refused to give Bagramian a written document in this regard, under the pretext that this flight could be too dangerous and such important orders should not fall into the hands of the enemy. In addition, leaving a written record of such disobedience to Stalin could have cost both their lives. However, after Bagramian delivered Timoshenko's verbal order to the commander of the Soviet Southwestern Front on September 17, Kirponos avoided implementing it until reception of written confirmation. Ignoring Bagramian's protests, he had decided to send a telegram to Moscow to receive the confirmation.

On the same day, Shaposhnikov and Vasilevsky "in a difficult conversation" were once again trying to convince Stalin to withdraw Kirponos' forces; Stalin accused the commanders of the Red Army of "weak resistance against the enemy", and agreed only with the withdrawal of the 5th and 37th armies to better defensive positions. Despite the breakdown in communications, Kirponos finally received a withdrawal confirmation from Shaposhnikov on the night of 17 September, but he was only allowed to leave Kyiv without retreating all the way to the Psel river. However, a few hours before the arrival of this order, Kirponos, on his own initiative, ordered the Soviet 5th, 21st and 37th armies to attack to the east in order to break the Germans armored wall. The 38th and 40th armies, from outside the encircled area, were also tasked to protect the flanks by attacking Rumny and Lubny in the north and south, respectively. However, due to being under attack from all directions, it was not possible to carry out a coordinated retreat.

Many of the Red Army forces efforts to break out of encirclement were made in a chaotic and unplanned manner. Most of these efforts had no organization and were accompanied with heavy casualties. The attempts to break the encirclement were generally made by a mass of infantry with little artillery support. However, the numerical superiority was often high enough that their efforts were not always fruitless. The attack of the Red Army forces from the east on 18 September partially split the German defense and penetrated to one kilometer from Rumny. At this time, Rumny was the headquarters of Panzer Group 2. Against the attack of two tank brigades, two rifle divisions and one or two cavalry divisions of the Red Army, Guderian had only two battalions of the 10th Motorized Infantry Division and a few anti-aircraft guns. The Soviet Air Force was able to gain local superiority, and targeted Rumny with its heavy bombers. Guderian requested help from the 14th Division of the Panzer Group 1 and ordered the transfer of a part of the SS Das Reich and 4th Panzer divisions from the inner ring to this location. The arrival of the SS division on 19 and 4 September Panzer launching a counterattack from the south prevented the loss of Rumny to the Soviets. Despite holding Rumny, Guderian moved his headquarters to Konotop.

Elsewhere, the encircled forces in the east of Piryatin launched a powerful attack against the positions of the German 35th Infantry Regiment of the 25th Infantry Division and by defeating them, temporarily broke the German line. The Panzer regiment of the 9th Panzer Division covered this breach with a successful counterattack. On the morning of 21 September, the attacks of the Red Army against the center of the 239th Infantry Division of the German XI Army Corps front line, not only caused a deep breach, but also surrounded the German 372nd Infantry Regiment. Lieutenant General Joachim von Kurtzfleisch, commander of the XI Army Corps, ordered a small force to be sent to this point from three other directions. At the same time, another breakthrough was achieved, this time on the left flank of the German 125th division of this Corps. These breaches caused the front line of the units to be mixed up and created a confused situation for the forces of both armies; noting this, a German soldier wrote in his memoirs: "Often one does not understand who is surrounded; Bolsheviks or us!".

Destruction of the pocket

On 1 September, the Soviet Southwestern Front had 850,000 troops (including 90,000 reserves and rearguard units), 3,923 cannons and mortars, 114 tanks and 167 combat aircraft. The area included 452,700 troops, 2,642 cannons and mortars, and 64 tanks. The Luftwaffe had absolute air superiority over the region by employing the II and V Air Corps. Despite supply problems, the Luftwaffe's air attacks caused significant damage to the encircled Soviet forces and disrupted their movements. The Luftwaffe 5th Air Corps carried out more than 1,400 sorties and dropped around 570,000 kilograms of bombs on the enemy between 12 and 21 September, causing the destruction of nearly 2,200 motor vehicles and 100 Soviet aircraft. The Luftwaffe only suffered 27 casualties and 17 aircraft shot down.

The Germans divided the encircled forces of the Soviet Southwestern Front into small isolated parts and destroyed them one by one by tightening the ring. The advance of the German 17th army to the east increased the distance between the besieged forces of the Soviet Southwestern Front and the rest of the Red army. The XLVIII Motorized Corps and 11th Panzer Group had not only kept the southern part of the eastern wall of the pocket, but also made the area more compact by attacking from the west. Simultaneously, the LI Army Corps of the German 6th army made a significant advance to the south against the scattered resistance of the northern flank of Kirponos. This Corps linked up with elements of the XXXIV Army Corps, which had gained a new frontline at Rezhishchev, south of Kyiv, to cut the encircled area in half. The actions of the Germans caused great confusion among the forces of the Soviet Southwestern Front. The disconnect between the Red Army units deprived it of the ability to coordinate and send orders. On 18 September, the Soviet 21st Army headquarters personnel, including three generals, were captured by the 4th Panzer Division. The next day, the pocket was divided into three parts. The largest part was around Boryspol, south-east of Kyiv, and consisted mainly of troops of the Soviet 37th Army. The other two major areas were a circular area west of Urzhitsa with the forces of the Soviet 26th Army, and the area between Priatin and Lukhvitsa with the remnants of the Soviet 5th and 26th Armies, commanded by Kirponos. The Soviet 5th and 21st armies was defeated by 23 September, and the Soviet 26th Army in the Orzhitsa region was defeated by 26 September. Small groups of Red Army soldiers were still scattered over a wide area, and some of these troops tried to escape in different ways, including in civilian clothes. Only about 15,000 managed to get out of the pocket by 2 October, including Vlasov, the commander of the 37th Army, Kostenko, the commander of the 26th Army, and Kuznetsov, the commander of the 21st Army, and Bagramian.

In addition to tactical and operational issues, for the security of the forces inside the city, the command of the German 6th Army decided that until the surrounding area of the Kyiv was completely cleared of any form of resistance, the German troops were only allowed to stay in it with the written permission of its headquarters. At the same time, a decree was issued in connection with the control of depots and maintaining order in Kyiv.

The battle for Kyiv itself began on 16 September with the assault of the General-Lieutenant Hans von Obstfelder XXIX Army Corps of the German 6th Army. The 71st and 296th infantry divisions were at the front of this offensive, breaking through the Soviet defensive positions. They were assisted by the 95th Infantry Division and the 3rd Battalion of the 77th Sturmgeschütz Regiment. Inside the city, the Soviet government tried to encourage the defenders to continue their resistance by broadcasting Stalin's speeches through loudspeakers. Kyiv was captured by German forces on 19 September but the clashes over this city continued until 24 September. Before its capture, important materials were evacuated from Kyiv and the railway lines were destroyed by the retreating Soviets.

On 19 September, the German 99th Light Division discovered explosive traps that had been placed in large buildings suitable for deploying troops and headquarters. Attempts were made to find and disarm these traps, but on 24 September, an explosion next to the main post office in a captured weapons and ammunition depot started a large fire that quickly spread. The firefighters of the Sachsen regiment were not able to extinguish the fire. In order to contain the fire, the 99th sapping Battalion and the demolition squads of the 71st and 99th Infantry Divisions cleared a large area as a fire break. The fire was finally extinguished on 29 September with the help of German soldiers, emergency units and other local and German firefighters. About 200 Germans died in the initial explosions or subsequent fires, and 10,000 to 25,000 civilians were left homeless. "Partisans and Jews" were accused to be responsible of these events. The headquarters of the 195th military administration was removed from Kyiv and the responsibility of city administration was entrusted to the commander of the 113th infantry division. Following these events, a two-day massacre of 33,000 Jews in Babi Yar took place.

As a result of the battle in the Kyiv region, four Soviet field armies including the 5th, 21st, 26th, and 37th armies with 43 divisions were completely destroyed. As a result of the fighting during September, according to official German reports, about 665,000 Red Army troops were captured, and 824 tanks, 418 anti-tank guns, and 3,000 artillery pieces were destroyed. However, the official history of the Soviet Union admits that the southwestern front had suffered heavy losses before the battle of Kyiv, and claims that it is unlikely that the number of prisoners was more than 222,000. On the other hand, there are no clear statistics on the amount of casualties of the German units involved in the battle of Kyiv, but the quoted reports indicate that the Wehrmacht suffered heavy losses.

The aerial blockade of the region was not completed and a number of senior Soviet commanders, including Budyonny, Timoshenko and Khrushchev, were able to escape by aircraft. By the evening of 20 September, Kirponos, together with the forces of the Soviet 5th Army, was able to reach Driukovshchyna, 15 kilometers southwest of Lukhovitsa. The Red Army column was attacked by the 3rd Panzer Division in this region. The Germans captured General Sotensky, the artillery commander of the Soviet 5th Army, and drove the enemy forces into the Shumikovo forests. Kirponos, Potapov, the commander of the Soviet Fifth Army, their staff officers and about 2,000 Soviet troops continued to fight for several more hours. Kirponos was leading his troops near the front line when he was seriously wounded in the left leg and taken deep into the forest. Shortly afterwards a mortar shell landed near him, killing him. With Kirponos killed, the remaining Soviet elements surrendered. Mykhailo Burmystenko, the commissar of the Soviet Southwestern Front, a member of the Central Committee of the Soviet Union Communist Party and the second secretary of the Communist Party of Ukraine, who died in this battle, was the highest-ranking Soviet communist leader who was killed during World War II.

Consequences

The battle of Kyiv can be considered an unprecedented defeat for the Red Army, which caused more damage than the battles of Minsk and Smolensk. The counter-attacks of the Soviet Bryansk front to prevent these incidents were unsuccessful and caused the loss of about 100,000 soldiers and 140 tanks out of an initial 260,000 soldiers and 260 tanks. After these defeats, the Bryansk front was in a chaotic state, and less than three weeks later, when the Wehrmacht's concentrated offensive toward Moscow began, it had only 200,000 troops to face it. With the Southwestern Front completely destroyed, the Soviets were forced to rebuild it from scratch and to fill the gap created in the south of the front line, transfer its forces from the central sector.

The victory in Kyiv was considered one of the prerequisites for advancing the Army Group Center. Once it was achieved, the German Army High Command and the Wehrmacht High Command (OKW), returned their focus to the central part of the front, and resumed their push to Moscow. With their success in the Kyiv region, a new hope was immediately created amongst German command about the success of this front. The destruction of the Soviet Southwestern Front opened the way for Army Group South to advance to the east of Ukraine without facing any resistance force. In addition, the large amount of equipment captured in the Kyiv region enabled the Wehrmacht to advance without waiting for resupply. Finally, during the eight weeks that the Battle of Kyiv was going on, the Army Group Center had the opportunity to recover and strengthen its worn-out forces and improve their supply situation, and its infantry divisions were able to join the motorized forces at the front line in a relatively slow march to the east.

The battle of Kyiv also delivered some positive results for the Soviet Union. Panzer Group 2's southward advance to encircle the Soviet Southwestern Front delayed the German advance toward Moscow for a month, eventually dragging the Wehrmacht's operations into winter which turned out to be costly. However, the Red army lost significant forces that could have been used to defend Moscow. In addition to dominating the vital economic lands of the Soviet Union, the Wehrmacht was able to secure the southern flank of its Army Group Center and deal a heavy blow to the Soviet Bryansk Axis forces, making their path towards Moscow smoother. Zhukov said about this:

We can imagine that without operation [in the direction of Ukraine], the situation of the German Army Group Center could have been even worse than It was found to be. Reserve forces of the [Soviet] High Command, which had been used in September to fill the gaps in the southwestern sector, could have been used in an attack on the flank and rear of the central group of the German armies advancing on Moscow.

Beyond the operational issues, in the strategic dimension, this victory was popularised to try to convince Turkey to join the war on the Axis side, and convince Finland to participate more. In this way, Germany could also put Iran under pressure in the south, for which Britain and the Soviet Union had plans.

The damage caused to the German forces due to the explosive traps planted in the city of Kyiv by the Soviets caused a change in the Wehrmacht's approach to capturing large cities in the continuation of Operation Barbarossa. Hitler forbade accepting such risks again and conquering large fortified cities with direct attacks, especially without Panzer units; rather, it was decided that these cities should be left behind and besieged by artillery fire and air attacks. During the final attack on Moscow on 7 October, Hitler used this strategy and prohibited the entry of troops into these cities.

The encirclement of the Kyiv region was the last successful major breakthrough of the Wehrmacht's Panzer forces over a long distance that the Germans were able to carry out in the Soviet Union.

Civilian impact

Despite the order for wholesale destruction of Kyiv issued in the Supplement to Directive 34 from 12 August, the city was spared, to Hitler's fury, as there had been no fighting within. The German troops, who occupied Kyiv on 19 September, were surprised by a series of explosions from Soviet radio-mines in the city centre from 24 September onwards, the first of which also killed a number of local civilians reporting at the German Field Command to surrender outlawed items. The resulting fire, which was not put out until 29 September, offered the Nazi authorities a pretext to commence the mass murder of Jews in Babi Yar on the same day. As the city had not been razed, the German leadership launched the plan to starve it while officially attributing the food shortages to the consequences of Soviet economic policies. Ultimately, the implementation of the Hunger Plan in occupied Kyiv was restrained by the fears of an uprising behind the lines, and the city was only forcibly evacuated and subjected to widespread looting and burning during the German withdrawal in September–November 1943.
