170 aircraft left from various bases to bomb the German city of Essen. The city was classed as one of the major industrial areas of Germany. During the war the area had been bombed on no less than 272 occasions.

This operation comprised 92 Wellingtons, 42 Halifaxes, 14 Stirlings, 13 Lancasters and 9 Hampdens.

97 Squadron sent 6 Lancasters each equipped with the 4,000 lb. cookie bomb and 8 x SBC lb. bombs. Weather conditions were good with 5-6/10ths cloud. Bombing was made from 17,000 ft, but proved to be inaccurate due to poor target identification, the city suffered only light damage with 13 people killed a further 42 injured on the ground.

4000 Lb bomb also known as a ‘Cookie’ and the blockbuster bomb - designed to devastate a small area or a large building - usually dropped with incendiaries.

SBC - Small Bomb Containers - usually containing incendiary bombs of various sizes.

Bombing results Essen 1942 - 1945

The RAF lost some 20 aircraft, 96 crew losing their lives, 1 taken PoW with 2 others evading capture. Most of the aircraft lost to the night fighters were over Holland. Lancaster R5495 was the only aircraft from the squadron failing to return, nothing was heard from them, no night fighter claims for this loss. It is thought probable they fell victim to flak over the target area. The remainder of the aircraft landed at just after 04.00 hrs.
