Battle of Raxus Prime
Shortly after the siege of Rhen Var, the Republic detected unusual activity on Raxus Prime, and sent a strike force led by Jedi Knights Anakin Skywalker and Obi-Wan Kenobi to investigate the activity.
On arrival, Anakin and Obi-Wan went to the surface to scout out the area. After they took out an enemy scout party, they discovered an enemy excavation site and contacted their assault ship for reinforcements.
Anakin and Obi-Wan made an attack on some supply convoys to stall for time so their strike force could land. Once the strike force landed, they fought their way to the excavation site, hampered by traps and surprise attacks. Eventually, they reach the excavation site, where there is a second group of Republic forces lying in wait. They destroy the shield generator, allowing the second strike team to enter the battlefield, and both teams simultaneously attack and destroy the remaining defenders, as well as the excavation cranes' fuel lines.
As the battle was winding down, Anakin spotted Count Dooku escaping in a Techno Union Transport and pursued him. Once the Union ship had lifted off, the Confederates unleashed their deadly assault machine, the Protodeka, which completely decimated the Republic strike force. Obi-Wan single-handedly destroyed the war machine, but by then Count Dooku's ship had already left the system with Anakin and his deadly machine.
