On this day in 1944, aero-engine factory, Limoges, France. 617 Squadron commander Cheshire made three low-level passes, warning civilians, before bombing commenced.
12 Lancasters of No 617 Squadron, led by its new commanding officer Wing Commander Leonard Cheshire, attacked the Gnome & Rhone aero-engine factory at Limoges in France. This was a very important raid. No 617 Squadron had been experiencing difficulty in finding a useful role after the Dams Raid nearly 9 months earlier. Low-level precision raids on targets in Germany had been too costly. High-level precision bombing on small targets in France and Belgium had been unsatisfactory, despite marking by Oboe-equipped Mosquitos. For this attack, Cheshire was given official permission to attempt low-level marking of this target, which had many French civilian houses near by. The factory was undefended, except for 2 machine-guns, and Cheshire made 3 low-level runs in bright moonlight to warn the French factory workers to escape. On his 4th run, he dropped a load of 30lb incendiaries from between 50 and 100ft. Each of 11 other Lancasters then dropped a 12,000lb bomb with great accuracy; 10 bombs hit the factory and the remaining one fell in the river alongside. The factory was severely damaged and production almost completely ceased. There were few if any casualties among the French people. No Lancasters were lost.
Despite the success of the low-level marking, it was never adopted by the Pathfinders, but was used on raids by No 617 Squadron and No 5 Group.
