WILHELMSHAVEN
338 aircraft - 120 Wellingtons, no Halifaxes, 56 Stirlings, 52 Lancasters. 12 aircraft - 5 Stirlings, 4 Lancasters, 3 Wellingtons - lost, 3.6 percent of the force.
This raid was another failure, with the Pathfinder marking causing the Main Force bombing to fall north of Wilhelmshaven. The local report says that only 3 people were slightly injured. After this raid it was found that the Pathfinders had been issued with out-of-date maps which did not show recent town developments. A general updating of maps now took place.
2 Mosquitoes bombed Dortmund and Essen without loss. The Essen bombs just missed the Krupps works.
