Five ships of the [[French Navy]] have borne the name ''Surcouf'', in honor of the [[18th century]] [[Saint-Malo]] corsair [[Robert Surcouf]]. For the modern [[frigate]], see [[FS Surcouf|FS ''Surcouf'']].


During the first years of [[World War II]], '''''Surcouf''''' was a French [[submarine]] ordered to be built in December [[1927]], [[ship naming and launching|launched]] [[18 October]] [[1929]], and [[ship commissioning|commissioned]] May [[1934]]. At the beginning of [[World War II]], ''Surcouf'' was the largest submarine in the world. Her short wartime career is laced with controversy and [[conspiracy theory|conspiracy theories]].
'''''Surcouf''''' {{IPA|fr|syʁ.kuf|}} was a large French gun-armed [[cruiser submarine]] of the mid 20th century. She carried two 203&nbsp;mm guns as well as anti-aircraft guns and (for most of her career) a floatplane. ''Surcouf'' served in the [[French Navy]] and, later, the [[Free French Naval Forces]] during the [[Second World War]].


''Surcouf'' disappeared during the night of 18/19 February 1942 in the [[Caribbean Sea]], possibly after colliding with the US freighter ''Thompson Lykes'', although this has not been definitely established. She was named after the French privateer and shipowner [[Robert Surcouf]]. She was the largest submarine built until surpassed by the first Japanese [[I-400-class submarine|I-400 class]] aircraft carrier submarine in 1944.
''Surcouf'' was designed as an "underwater [[cruiser]]," intended to seek and engage in surface combat. For the first part of that mission, it carried an observation float plane in a hangar built into the after part of the conning tower; for the second part, it was armed with not only ten torpedo tubes but also a twin eight-inch gun turret forward of the conning tower. The guns were fed from a magazine holding 600 rounds and controlled by a director with a 40-foot rangefinder, mounted high enough to view a seven-mile horizon. In theory, the observation plane could direct fire out to the guns' fifteen-mile maximum range. Antiaircraft cannon and machineguns were mounted on the top of the hangar.


==Design==
''Surcouf'' also carried a 16-foot motorboat, and contained a cargo compartment with fitting to restrain 40 prisoners. The submarine's fuel tanks were very large; enough fuel for a 10,000-nautical-mile range and supplies for 90-day patrols could be carried.


The [[Washington Naval Treaty]] had placed strict limits on naval construction by the major naval powers in regard to displacements and artillery calibers of battleships and cruisers. However, no agreements were reached in respect of light ships such as frigates, destroyers or submarines. In addition, to ensure the country's protection and that of the empire, France started the construction of an important [[List of submarines of France|submarine fleet]] (79 units in 1939). ''Surcouf'' was intended to be the first of a class of three submarine cruisers; however, she was the only one completed.
In [[1940]], ''Surcouf'' was homeported in [[Cherbourg]], but in June, when the Germans invaded, was undergoing refit in [[Brest, France]]. With only one engine functioning and with a jammed rudder, she limped across the [[English Channel]] and sought refuge in [[Portsmouth]]. On [[3 July]], the British carried out [[Operation Catapult]] -- concerned that the French would deliver their fleet to the [[Kriegsmarine]] when they surrendered, the [[Royal Navy]] blockaded numerous harbors in which French ships were anchored and ordered them to surrender to the British. Most yielded willingly, with two notable exceptions: the North African fleet, which condemned the British "treachery" and suffered hundreds of casualties when [[Destruction of the French Fleet at Mers-el-Kebir|the British opened fire]], and ''Surcouf''. In capturing the submarine, two British officers and one French sailor were killed. The acrimony between the British and French caused by these actions escalated when the British attempted to repatriate the captured French sailors. The British hospital ship that was carrying them back to France was sunk by the Germans, so the French blamed the British for the deaths.


The missions revolved around:
By August [[1940]], the British completed <i>Surcouf</i>'s refit and turned her over to the [[Free French Naval Forces]] (''Forces Navales Fran&ccedil;aises Libres'', FNFL) for convoy patrol. The only officer remaining from the original crew, Louis Blaison, became the new commander. Because of the British-French tensions with regard to the submarine, accusations were made by each side that the other was spying for [[Vichy France]]; the British added that ''Surcouf'' was sinking British ships. A British officer and two sailors were put on board for "liaison" purposes.
* Ensuring contact with the [[List of French possessions and colonies|French colonies]];
* In collaboration with French naval squadrons, searching for and destroying enemy fleets;
* Pursuing enemy convoys.


''Surcouf'' had a twin-gun turret with [[203mm/50 Modèle 1924 gun|203&nbsp;mm (8-inch) guns]], the same calibre as the guns of a [[heavy cruiser]], provisioned with 60 rounds. She was designed as an "underwater heavy cruiser", intended to seek out and engage in surface combat.<ref>{{cite book |last=Winchester |first=Clarence |year=1937 |title=Shipping wonders of the world |volume=41–55 |publisher=Amalgamated Press |page=1431}}</ref> The boat carried a [[Besson MB.411]] observation [[floatplane]] in a hangar built aft of the [[conning tower]] for reconnaissance and [[Artillery observer|observing fall of shot]].
In December [[1941]], ''Surcouf'' carried the Free French Admiral [[Emile-Henri Muselier]] to [[Canada]], putting in to [[Quebec City]]. While the Admiral was in [[Ottawa]], conferring with the Canadian government, <i>Surcouf</i>'s captain was approached by famous <cite>[[New York Times]]</cite> reporter [[Ira Wolfert]] and questioned about the rumors that the submarine would liberate [[Saint-Pierre and Miquelon]] (an archipelago some 30 kilometers off the southeastern shore of [[Newfoundland]]). It is highly unlikely that the captain, as some sensational stories have it, kidnapped the reporter, smuggled him to the submarine in the trunk of a car, and imprisoned him aboard, but he did accompany the submarine to [[Halifax, Nova Scotia]] where, on [[20 December]], they joined the Free French [[corvette]]s ''Mimosa'', ''Aconit'', and ''Alysse'', and on [[24 December]] handily captured the islands.


The boat was equipped with ten [[torpedo tube]]s: four {{convert|550|mm|in|abbr=on}} tubes in the bow, and two swiveling external launchers in the aft superstructure, each with one 550&nbsp;mm and two {{convert|400|mm|in|abbr=on}} [[torpedo]] tubes. Eight 550&nbsp;mm and four 400&nbsp;mm reloads were carried.<ref>{{cite book |last1=Huan |first1=Claude |year=1996 |title=Le croiseur sous-marin Surcouf |location=Bourg en Bresse |publisher=Marines editions |pages=53–54}}</ref> The 203&nbsp; Modèle 1924 guns were in a pressure-tight turret forward of the conning tower. The guns had a 60-round magazine capacity and were controlled by a [[Director (military)|director]] with a {{convert|5|m|ft|abbr=on}} rangefinder, mounted high enough to view an {{convert|11|km|nmi mi|lk=on|abbr=on}} horizon, and able to fire within three minutes after surfacing.<ref name=Netmarine-Main/> Using the boat's periscopes to direct the fire of the main guns, ''Surcouf'' could increase the visible range to {{convert|16|km|nmi mi|abbr=on}}; originally an elevating platform was supposed to lift lookouts {{convert|15|m|ft|abbr=on}} high, but this design was abandoned quickly due to the effect of [[Ship motions#Reference axes|roll]].<ref name=Netmarine-Caracter>[http://netmarine.net/g/bat/surcouf/caracter.htm Sous-marin croiseur ''Surcouf'': Caractéristiques principales]</ref>
[[United States Secretary of State]] [[Cordell Hull]], who had just concluded an agreement with the Vichy government for the neutrality of French possessions in the Western hemisphere, threatened to resign unless [[President of the United States]] [[Franklin Roosevelt]] demanded a restoration of the status quo. Roosevelt did so, but when [[Charles de Gaulle]] refused, he dropped the matter. Ira Wolfert's stories, very favorable to the Free French (and bearing no sign of kidnapping or other duress), helped swing American popular opinion away from Vichy.
The Besson observation plane could be used to direct fire out to the guns' {{convert|26|mi|nmi km|abbr=on}} maximum range. Anti-aircraft cannon and machine guns were mounted on the top of the hangar.


''Surcouf'' also carried a {{convert|4.5|m|ftin|abbr=on}} motorboat, and contained a cargo compartment with fittings to restrain 40 prisoners or lodge 40 passengers. The submarine's fuel tanks were very large; having enough fuel for a {{convert|10000|nmi|km mi|abbr=on}} range and supplies for 90-day patrols.
However, it is rumored &mdash; entirely without supporting evidence &mdash; that on [[1 January]] [[1942]], an American [[destroyer]] was sent to Saint-Pierre to restore it to Vichy control and was fired upon by ''Surcouf'', killing one or two American sailors. Obviously, the incident would have been hushed up. It is documented, however, that in that month, the Free French decided to send ''Surcouf'' to the Pacific theater of war, and she put in to [[Bermuda]] for resupply. Her movement south triggered rumors that she was going to liberate [[Martinique]].


The test depth was {{convert|80|m|ft|abbr=on}}.
On [[18 February]] [[1942]], ''Surcouf'' was lost with all hands. At the time, her loss was the greatest single submarine casualty ever. The investigation commission eventually stated that the ''Surcouf'' had been sunk by US planes in the morning of the 18th in "[[friendly fire]]", though the official report stated that she left Bermuda on [[12 February]] and was accidentally rammed and sunk by the American freighter ''Thompson Lykes'' near the [[Panama canal]] (both vessels were running at night with no lights, due to the menace of German [[U-boat]]s).


The first commanding officer was [[Frigate Captain]] (''Capitaine de Frégate'', a rank equivalent to [[Commander]]) Raymond de Belot.
Like so much else about ''Surcouf'', there are alternate stories of her end. Disregarding the predictable ones about her being swallowed by the [[Bermuda Triangle]], one of the most popular is that she was caught in [[Long Island Sound]] refueling a German [[U-boat]], and both submarines were sunk, either by the American submarines
[[USS Mackerel (SS-204)|''Mackerel'' (SS-204)]]
and
[[USS Marlin (SS-205)|''Marlin'' (SS-205)]]
or a [[US Coast Guard]] blimp.


The boat encountered several technical challenges:
Many stories add that much of the gold from the French Treasury was in <i>Surcouf</i>'s large cargo compartment, and that the wreck was found and entered in [[1967]] by [[Jacques Cousteau]]. Obviously he, too, was persuaded to remain silent.
* Because of the low height of the rangefinder above the water surface, the practical range of fire was {{convert|12000|m|yd|abbr=on}} with the rangefinder, increased to {{convert|16000|m|yd|abbr=on}} with sighting aided by periscope, well below the guns' maximum range of {{convert|26000|m|yd|abbr=on}}.
* The duration between the surface order and the first firing round was 3 minutes and 35 seconds. This duration would be longer if the boat was to fire [[Broadside (naval)|broadside]], which meant surfacing and [[Training (gunnery)|training]] the turret in the desired direction.
* Firing had to occur at a precise moment of pitch and roll when the ship was level.
* Training the turret to either side was impossible when the ship rolled 8° or more.
* ''Surcouf'' could not fire accurately at night, as fall of shot could not be observed in the dark.
* The guns' ready [[Magazine (artillery)|magazines]] had to be reloaded after firing 14 rounds from each gun.


To replace the floatplane, whose functioning was initially constrained and limited in use, trials were conducted with an [[autogyro]] in 1938.
== Aircraft ==
The MB.410 and MB.411 were observation aircraft, designed to be carried by <i>Surcouf</i>. They were low-wing monoplanes with a single central float and two small stabilizing floats, that could easily be disassambled for stowage. One MB.410 and two MB.411s were built; one MB.411 was carried on board.

'From the beginning of the boat's career until 1932, the boat was painted the same grey colour as surface warships, but thereafter in ''[[Prussian blue|Prussian dark blue]]'', a colour which was retained until the end of 1940 when it was repainted with two tones of grey, serving as camouflage on the hull and conning tower.

[[ja:&#12471;&#12517;&#12523;&#12463;&#12540;&#12501;]]
===Early career===

Soon after ''Surcouf'' was launched, the [[London Naval Treaty]] finally placed restrictions on submarine designs. Among other things, each signatory (France included) was permitted to possess no more than three large submarines, each not exceeding {{convert|2800|LT|t|0|abbr=on}} standard displacement, with guns not exceeding {{convert|6.1|in|mm|abbr=on}} in caliber. ''Surcouf'', which would have exceeded these limits, was specially exempt from the rules at the insistence of Navy Minister [[Georges Leygues]],<ref name=Netmarine-Main>[http://netmarine.net/g/bat/surcouf/index.htm Croiseur sous-marin ''Surcouf''], netmarine</ref> but other 'big-gun' submarines of this boat's class could no longer be built.

===Second World War===

In 1940, ''Surcouf'' was based in [[Cherbourg-Octeville|Cherbourg]], but in May, when the Germans invaded, she was being refitted in [[Brest, France|Brest]] following a mission in the [[Antilles]] and [[Gulf of Guinea]]. Under command of Frigate Captain Martin, unable to dive and with only one engine functioning and a jammed rudder, she limped across the [[English Channel]] and sought refuge in [[Plymouth]].

On 3 July, the British, concerned that the French Fleet would be taken over by the German ''[[Kriegsmarine]]'' at the French armistice, executed [[Attack on Mers-el-Kébir#Operation Catapult|Operation Catapult]]. The [[Royal Navy]] blockaded the harbours where French warships were anchored, and delivered an ultimatum: rejoin the fight against Germany, be put out of reach of the Germans, or scuttle. Few accepted willingly; the North African fleet at [[Mers-el-Kebir]] and the [[Battle of Dakar#Background|ships based at Dakar]] (French West Africa) refused. The French battleships in North Africa were eventually attacked and all but one sunk at their moorings by the [[Mediterranean Fleet]].

French ships lying at ports in Britain and Canada were also boarded by armed marines, sailors and soldiers, but the only serious incident took place at [[Plymouth]] aboard ''Surcouf'' on 3 July, when two Royal Navy submarine officers, [[Commander]] Denis 'Lofty' Sprague, captain of {{HMS|Thames|N71|6}}, and [[Lieutenant]] Patrick Griffiths of {{HMS|Rorqual|N74|6}},<ref name="Phoenix paperback">{{cite book|last1=Smith|first1=Colin|title=England's last war against France: Fighting Vichy 1940–42|date=24 June 2010|publisher=Phoenix |edition=paperback|isbn=978-0-7538-2705-5|at=Chapter 4}}</ref><ref>{{citation |url=http://www.naval-history.net/xDKCas1940-07JUL.htm |title=1st – 31st July 1940 |work=Casualty Lists of the Royal Navy and Dominion Navies, World War 2 |first=Don |last=Kindell |date= 12 June 2011 |editor= Gordon Smith}}</ref> and French warrant officer mechanic Yves Daniel<ref name=Netmarine-Histoire>{{citation |url=http://netmarine.net/g/bat/surcouf/histoire.htm |title=Histoire du sous-marin ''Surcouf'' |publisher=netmarine |language=fr}}</ref> were fatally wounded, and a British seaman, Albert Webb,<ref name="Phoenix paperback"/> was shot dead by the submarine's doctor.<ref>{{cite book |last1=Brown |first1=David |last2=Till |first2=Geoffrey |year=2004 |title=The Road to Oran: Anglo-French Naval Relations, September 1939 – July 1940 |publisher=[[Routledge]] |isbn=0-7146-5461-2 |page=182}}</ref>

===Free French Naval Forces===
By August 1940, the British completed ''Surcouf''{{'}}s refit and turned her over to the [[Free French Naval Forces]] (''Forces Navales Françaises Libres'', FNFL) for convoy patrol. The only officer not repatriated from the original crew, Frigate Captain Georges Louis Blaison, became the new commanding officer. Because of Anglo-French tensions with regard to the submarine, accusations were made by each side that the other was spying for [[Vichy France]]; the British also claimed ''Surcouf'' was attacking British ships. Later, a British officer and two sailors were put aboard for "liaison" purposes. One real drawback was she required a crew of 110–130 men, which represented three crews of more conventional submarines. This led to Royal Navy reluctance to recommission her.

''Surcouf'' then went to the Canadian base at [[City of Halifax|Halifax]], [[Nova Scotia]] and escorted trans-Atlantic convoys. In April 1941, she was damaged by a German plane at Devonport.<ref name=Netmarine-Histoire/>

On 28 July, ''Surcouf'' went to the [[Portsmouth Naval Shipyard|United States Naval Shipyard]] at Kittery, Maine for a three-month refit.<ref name =Netmarine-Main/>

After leaving the shipyard, ''Surcouf'' went to [[New London, Connecticut]], perhaps to receive additional training for her crew. ''Surcouf'' left New London on 27 November to return to Halifax.

===Capture of St. Pierre and Miquelon===
{{main|Capture of Saint Pierre and Miquelon}}
[[File:St-pierre-et-miquelon-stamp-1961-(Surcouf-submarine).png|thumb|French postage stamp celebrating the "capture" of Saint Pierre and Miquelon (1961).]]
In December 1941, ''Surcouf'' carried the Free French Admiral [[Émile Muselier]] to Canada, putting into [[Quebec City]]. While the Admiral was in [[Ottawa]], conferring with the Canadian government, ''Surcouf''{{'}}s captain was approached by ''[[The New York Times]]'' reporter [[Ira Wolfert]] and questioned about the rumours the submarine would liberate [[Saint-Pierre and Miquelon]] for Free France. Wolfert accompanied the submarine to Halifax, where, on 20 December, they joined Free French [[List of escorteurs of the French Navy|"Escorteurs"]] [[corvette]]s ''Mimosa'', {{Ship|French corvette|Aconit||2}}, and {{Ship|French corvette|Alysse||2}}, and on 24 December, [[Capture of Saint Pierre and Miquelon|took control]] of the islands for Free France without resistance.

[[United States Secretary of State]] [[Cordell Hull]] had just concluded an agreement with the Vichy government guaranteeing the neutrality of French possessions in the Western hemisphere, and he threatened to resign unless President of the United States [[Franklin D. Roosevelt]] demanded a restoration of the status quo. Roosevelt did so, but when [[Charles de Gaulle]] refused, Roosevelt dropped the matter. Ira Wolfert's stories – very favourable to the Free French (and bearing no sign of kidnapping or other duress) – helped swing American popular opinion away from Vichy. The Axis Powers' [[Axis powers#Germany.27s and Italy.27s declaration of war against the United States|declaration of war on the United States]] in December 1941 negated the agreement, but the U.S. did not sever diplomatic ties with the Vichy Government until November 1942.

===Later operations===
In January 1942, the Free French leadership decided to send ''Surcouf'' to the [[Pacific War|Pacific theatre]], after she had been re-supplied at the [[Royal Naval Dockyard, Bermuda|Royal Naval Dockyard]] in [[Bermuda]]. However, her movement south triggered rumours that ''Surcouf'' was going to liberate [[Martinique]] from the Vichy regime.

In fact, ''Surcouf'' was bound for [[Sydney]], Australia, via Tahiti.<ref name=Netmarine-Main/> She departed Halifax on 2 February for Bermuda, which she left on 12 February, bound for the [[Panama Canal]].<ref name=Netmarine-Histoire/>

===Fate===
[[File:Free French Memorial, Greenock, west plaque & wreath.jpg|thumb|The Free French Memorial on [[Lyle Hill]], [[Greenock]]: ''À la mémoire du Capitaine de frégate Blaison, des officiers et de l'équipage du sous-marin Surcouf perdu dans l'Atlantique Février 1942'' ("To the memory of Frigate Captain Blaison, the officers[,] and the crew of the submarine Surcouf[,] lost in the Atlantic February 1942").]]
''Surcouf'' vanished on the night of 18/19 February 1942, about {{convert|130|km|nmi|abbr=on}} north of [[Cristóbal, Colón|Cristóbal, Panama]], while ''en route'' for [[Tahiti]], ''via'' the [[Panama Canal]].

Surcouf [syʁ.kuf] was a large French gun-armed cruiser submarine of the mid 20th century. She carried two 203 mm guns as well as anti-aircraft guns and (for most of her career) a floatplane. Surcouf served in the French Navy and, later, the Free French Naval Forces during the Second World War.

Surcouf disappeared during the night of 18/19 February 1942 in the Caribbean Sea, possibly after colliding with the US freighter Thompson Lykes, although this has not been definitely established. She was named after the French privateer and shipowner Robert Surcouf. She was the largest submarine built until surpassed by the first Japanese I-400 class aircraft carrier submarine in 1944.

Design

[edit]

The Washington Naval Treaty had placed strict limits on naval construction by the major naval powers in regard to displacements and artillery calibers of battleships and cruisers. However, no agreements were reached in respect of light ships such as frigates, destroyers or submarines. In addition, to ensure the country's protection and that of the empire, France started the construction of an important submarine fleet (79 units in 1939). Surcouf was intended to be the first of a class of three submarine cruisers; however, she was the only one completed.

The missions revolved around:

  • Ensuring contact with the French colonies;
  • In collaboration with French naval squadrons, searching for and destroying enemy fleets;
  • Pursuing enemy convoys.

Surcouf had a twin-gun turret with 203 mm (8-inch) guns, the same calibre as the guns of a heavy cruiser, provisioned with 60 rounds. She was designed as an "underwater heavy cruiser", intended to seek out and engage in surface combat.[2] The boat carried a Besson MB.411 observation floatplane in a hangar built aft of the conning tower for reconnaissance and observing fall of shot.

The boat was equipped with ten torpedo tubes: four 550 mm (22 in) tubes in the bow, and two swiveling external launchers in the aft superstructure, each with one 550 mm and two 400 mm (16 in) torpedo tubes. Eight 550 mm and four 400 mm reloads were carried.[3] The 203  Modèle 1924 guns were in a pressure-tight turret forward of the conning tower. The guns had a 60-round magazine capacity and were controlled by a director with a 5 m (16 ft) rangefinder, mounted high enough to view an 11 km (5.9 nmi; 6.8 mi) horizon, and able to fire within three minutes after surfacing.[4] Using the boat's periscopes to direct the fire of the main guns, Surcouf could increase the visible range to 16 km (8.6 nmi; 9.9 mi); originally an elevating platform was supposed to lift lookouts 15 m (49 ft) high, but this design was abandoned quickly due to the effect of roll.[5] The Besson observation plane could be used to direct fire out to the guns' 26 mi (23 nmi; 42 km) maximum range. Anti-aircraft cannon and machine guns were mounted on the top of the hangar.

Surcouf also carried a 4.5 m (14 ft 9 in) motorboat, and contained a cargo compartment with fittings to restrain 40 prisoners or lodge 40 passengers. The submarine's fuel tanks were very large; having enough fuel for a 10,000 nmi (19,000 km; 12,000 mi) range and supplies for 90-day patrols.

The test depth was 80 m (260 ft).

The first commanding officer was Frigate Captain (Capitaine de Frégate, a rank equivalent to Commander) Raymond de Belot.

The boat encountered several technical challenges:

  • Because of the low height of the rangefinder above the water surface, the practical range of fire was 12,000 m (13,000 yd) with the rangefinder, increased to 16,000 m (17,000 yd) with sighting aided by periscope, well below the guns' maximum range of 26,000 m (28,000 yd).
  • The duration between the surface order and the first firing round was 3 minutes and 35 seconds. This duration would be longer if the boat was to fire broadside, which meant surfacing and training the turret in the desired direction.
  • Firing had to occur at a precise moment of pitch and roll when the ship was level.
  • Training the turret to either side was impossible when the ship rolled 8° or more.
  • Surcouf could not fire accurately at night, as fall of shot could not be observed in the dark.
  • The guns' ready magazines had to be reloaded after firing 14 rounds from each gun.

To replace the floatplane, whose functioning was initially constrained and limited in use, trials were conducted with an autogyro in 1938.

Appearance

[edit]

'From the beginning of the boat's career until 1932, the boat was painted the same grey colour as surface warships, but thereafter in Prussian dark blue, a colour which was retained until the end of 1940 when it was repainted with two tones of grey, serving as camouflage on the hull and conning tower.

Career

[edit]

Early career

[edit]

Soon after Surcouf was launched, the London Naval Treaty finally placed restrictions on submarine designs. Among other things, each signatory (France included) was permitted to possess no more than three large submarines, each not exceeding 2,800 long tons (2,845 t) standard displacement, with guns not exceeding 6.1 in (150 mm) in caliber. Surcouf, which would have exceeded these limits, was specially exempt from the rules at the insistence of Navy Minister Georges Leygues,[4] but other 'big-gun' submarines of this boat's class could no longer be built.

In 1940, Surcouf was based in Cherbourg, but in May, when the Germans invaded, she was being refitted in Brest following a mission in the Antilles and Gulf of Guinea. Under command of Frigate Captain Martin, unable to dive and with only one engine functioning and a jammed rudder, she limped across the English Channel and sought refuge in Plymouth.

On 3 July, the British, concerned that the French Fleet would be taken over by the German Kriegsmarine at the French armistice, executed Operation Catapult. The Royal Navy blockaded the harbours where French warships were anchored, and delivered an ultimatum: rejoin the fight against Germany, be put out of reach of the Germans, or scuttle. Few accepted willingly; the North African fleet at Mers-el-Kebir and the ships based at Dakar (French West Africa) refused. The French battleships in North Africa were eventually attacked and all but one sunk at their moorings by the Mediterranean Fleet.

French ships lying at ports in Britain and Canada were also boarded by armed marines, sailors and soldiers, but the only serious incident took place at Plymouth aboard Surcouf on 3 July, when two Royal Navy submarine officers, Commander Denis 'Lofty' Sprague, captain of HMS Thames, and Lieutenant Patrick Griffiths of HMS Rorqual,[6][7] and French warrant officer mechanic Yves Daniel[8] were fatally wounded, and a British seaman, Albert Webb,[6] was shot dead by the submarine's doctor.[9]

Free French Naval Forces

[edit]

By August 1940, the British completed Surcouf's refit and turned her over to the Free French Naval Forces (Forces Navales Françaises Libres, FNFL) for convoy patrol. The only officer not repatriated from the original crew, Frigate Captain Georges Louis Blaison, became the new commanding officer. Because of Anglo-French tensions with regard to the submarine, accusations were made by each side that the other was spying for Vichy France; the British also claimed Surcouf was attacking British ships. Later, a British officer and two sailors were put aboard for "liaison" purposes. One real drawback was she required a crew of 110–130 men, which represented three crews of more conventional submarines. This led to Royal Navy reluctance to recommission her.

Surcouf then went to the Canadian base at Halifax, Nova Scotia and escorted trans-Atlantic convoys. In April 1941, she was damaged by a German plane at Devonport.[8]

On 28 July, Surcouf went to the United States Naval Shipyard at Kittery, Maine for a three-month refit.[4]

After leaving the shipyard, Surcouf went to New London, Connecticut, perhaps to receive additional training for her crew. Surcouf left New London on 27 November to return to Halifax.

Capture of St. Pierre and Miquelon

[edit]

In December 1941, Surcouf carried the Free French Admiral Émile Muselier to Canada, putting into Quebec City. While the Admiral was in Ottawa, conferring with the Canadian government, Surcouf's captain was approached by The New York Times reporter Ira Wolfert and questioned about the rumours the submarine would liberate Saint-Pierre and Miquelon for Free France. Wolfert accompanied the submarine to Halifax, where, on 20 December, they joined Free French "Escorteurs" corvettes Mimosa, Aconit, and Alysse, and on 24 December, took control of the islands for Free France without resistance.

United States Secretary of State Cordell Hull had just concluded an agreement with the Vichy government guaranteeing the neutrality of French possessions in the Western hemisphere, and he threatened to resign unless President of the United States Franklin D. Roosevelt demanded a restoration of the status quo. Roosevelt did so, but when Charles de Gaulle refused, Roosevelt dropped the matter. Ira Wolfert's stories – very favourable to the Free French (and bearing no sign of kidnapping or other duress) – helped swing American popular opinion away from Vichy. The Axis Powers' declaration of war on the United States in December 1941 negated the agreement, but the U.S. did not sever diplomatic ties with the Vichy Government until November 1942.

Later operations

[edit]

In January 1942, the Free French leadership decided to send Surcouf to the Pacific theatre, after she had been re-supplied at the Royal Naval Dockyard in Bermuda. However, her movement south triggered rumours that Surcouf was going to liberate Martinique from the Vichy regime.

In fact, Surcouf was bound for Sydney, Australia, via Tahiti.[4] She departed Halifax on 2 February for Bermuda, which she left on 12 February, bound for the Panama Canal.[8]

Fate

[edit]
The Free French Memorial on Lyle Hill, Greenock: À la mémoire du Capitaine de frégate Blaison, des officiers et de l'équipage du sous-marin Surcouf perdu dans l'Atlantique Février 1942 ("To the memory of Frigate Captain Blaison, the officers[,] and the crew of the submarine Surcouf[,] lost in the Atlantic February 1942").

Surcouf vanished on the night of 18/19 February 1942, about 130 km (70 nmi) north of Cristóbal, Panama, while en route for Tahiti, via the Panama Canal. An American report concluded the disappearance was due to an accidental collision with the American freighter Thompson Lykes. Steaming alone from Guantanamo Bay on what was a very dark night, the freighter reported hitting and running down a partially submerged object which scraped along her side and keel. Her lookouts heard people in the water but, thinking she had hit a U-boat, the freighter did not stop although cries for help were heard in English. A signal was sent to Panama describing the incident.[10][11]

The loss resulted in 130 deaths (including 4 Royal Navy personnel), under the command of Frigate Captain Georges Louis Nicolas Blaison.[12] The loss of Surcouf was announced by the Free French Headquarters in London on 18 April 1942, and was reported in The New York Times the next day.[13] It was not reported Surcouf was sunk as the result of a collision with the Thompson Lykes until January 1945.[14]

The investigation of the French commission concluded the disappearance was the consequence of misunderstanding. A Consolidated PBY, patrolling the same waters on the night of 18/19 February, could have attacked Surcouf believing her to be German or Japanese.

Inquiries into the incident were haphazard and late, while a later French inquiry supported the idea that the sinking had been due to "friendly fire"; this conclusion was supported by Rear Admiral Gabriel Auphan in his book The French Navy in World War II.[15] Charles de Gaulle stated in his memoirs[16] that Surcouf "had sunk with all hands".

As no one has officially dived or verified the wreck of Surcouf, her location is unknown. If one assumes the Thompson Lykes incident was indeed the event of Surcouf's sinking, then the wreck would lie 3,000 m (9,800 ft) deep at 10°40′N 79°32′W / 10.667°N 79.533°W / 10.667; -79.533.[4]

A monument commemorates the loss in the port of Cherbourg in Normandy, France.[17] The loss is also commemorated by the Free French Memorial on Lyle Hill in Greenock, Scotland.[18]

Model of Surcouf in Paris.

As there is no conclusive confirmation that Thompson Lykes collided with Surcouf, and her wreck has yet to be discovered, there are alternative stories of her fate. James Rusbridger examined some of these theories in his book Who Sank Surcouf?, finding them all easily dismissible except one: the records of the 6th Heavy Bomber Group operating out of Panama show them sinking a large submarine the morning of 19 February. Since no German submarine was lost in the area on that date, she could have been Surcouf. He suggested the collision had damaged Surcouf's radio and the stricken boat limped towards Panama hoping for the best.[19]

A conspiracy theory, based on no significant evidence, held that the Surcouf, during her stationing at New London in late 1941, had been caught treacherously supplying a German U-boat in Long Island Sound, pursued by the American training subs Marlin and Mackerel out of New London, and sunk. The rumor circulated into the early 21st century, but is false since the Surcouf's later movements south are well documented.[20]

[edit]

The Surcouf is the subject of an underwater search by the fictional organization NUMA and international terrorists in the Clive Cussler novel "The Corsican Shadow", published in 2023. Cussler and his co-writer, Dirk Cussler, writes the Surcouf's wreck was discovered "...some eighty miles off the Panama coast." The sinking is even attributed to Surcouf's radio antenna being damaged in the collision with the Thompson Lykes, and then finished off by the reported attack of an A-17 bomber the next morning.
