26/27 March 1942
Essen
104 Wellingtons and 11 Stirlings. 10 Wellingtons and 1 Stirling lost.
The bombing force encountered heavy Flak at the target and many night fighters on the routes. Hits on the Krupps works and fires in Essen were claimed but the raid was actually another failure on this difficult target. Only 22 high-explosive bombs were counted in Essen, with 2 houses destroyed, 6 people killed and 14 injured. The bombers had suffered nearly 10 per cent casualties.
