After the French capitulation in 1940, Louis Renault refused to produce tanks for Nazi Germany, which took control of his factories. As Renault was manufacturing the Renault UE tank for the Allies, he produced trucks instead. On 3 March 1942, the British Royal Air Force (RAF) launched 235 low-level bombers at the Île Seguin, Billancourt, Paris plant, the largest number aimed at a single target during the war. of bombs were dropped on the plant and the surrounding area, causing extensive damage along with heavy civilian casualties. Renault resolved to rebuild the factory as quickly as possible, but bombardments continued a year later, on 4 April, this time delivered by the Americans, and on 3 and 15 September 1943.
