This raid, on the _koda 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 _koda factory visually; the Pathfinder markers were only intended as a general guide. In the event, 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 _koda factory was not hit. One report says that 200 German soldiers were killed when their barracks near the asylum was bombed.
