This raid, on the Skoda armaments factory, took place by the light of a full moon but was not a success, In a complicated plan, the Main Force was ordered to confirm the position of' the Skoda factory visually; the Pathfinder markers were only intended as a general gulde,As it turned out a large asylum building 7 miles away was mistaken for the factory and only 6 crews brought back bombing photographs which were within 3 miles of the real target. The Skoda factory was not hit. One report says that 200 German soldiers were killed when their barracks near the asylum were bombed.
