705 aircraft - 476 Lancasters, 207 Halifaxes, 22 Mosquitoes. The sudden switch by Bomber Command to a Ruhr target just across the German frontier caught the German fighter controllers by surprise and only 9 aircraft- 6 Lancasters, 3 Halifaxes - were lost, 1·3 per cent of the force.
Essen was covered by cloud but the Oboe Mosquitoes marked the target well and this was a successful attack. 48 industrial buildings were seriously damaged and 1,756 houses destroyed. 550 people were killed, 49 missing and 1,569 were injured. .The figures for killed and missing are broken down in the Essen report as follows:
Germans - 192 women, 155 men, 27 children, 6 soldiers, 4 policemen and 2 Hitler Youth. Foreigners - 74 forced workers and I prisoner of war. The remaining 138 victims were mixed German and foreign concentration-camp prisoners, large numbers of whom were now providing the labour forces in German factories.
