Taking off at 22:28 hrs from RAF Bourn, Cambridgeshire bomb the port and city of Hamburg joining 776 other aircraft on the third raid on this target within the last five days. 340 Lancasters, 244 Halifaxes, 119 Stirlings, 70 Wellingtons and 4 Mosquitoes made up the force. The Lancaster was carrying 6 x TI, 1 X 4,000 lb. and 3 x 1,000 lb. bomb load.

The idea was that the target be approached from the north to concentrate on the northern area of Hamburg which had not been bombed on previous occasions. The pathfinders dropped their markers too far east of the city. 707 aircraft got through to the target, dropping a total of 2,318 tons of bombs on residential areas - no figures are available as to the casualties on the ground for this raid although it is known that over 40,000 were killed during that week and over 16,000 residential buildings were destroyed.

The worst incident was when bombs hit a large department store in Wandsbek - the building collapsed and blocked exits from a shelter that was in the basement - 370 people died from poisoning by the fumes from a coke store nearby. 1,200,000 people fled the city after these raids.

The allies lost 31 aircraft on this operation with 176 aircrew losing their lives and a further 17 being made PoW.

Most of the aircraft were shot down by the Luftwaffe night fighters, although 14 were shot down by searchlight assisted flak over the target area.
