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.

97 Squadron lost another crew on his operation:

Lancaster III EE172 OF-O Flown by 27 year old Canadian, P/O. Clifford Schnier, killed with all his crew.

This Lancaster III ED862 was lost without trace although it is classed as 'probably' shot down by the Luftwaffe nightfighter ace Maj. Helmut Lent (1)of Stab IV./NJG1 over the North Sea at 02.10. The combat is understood to have taken place at 3.800 mtrs 20 kilometres North of Ameland.

We have also been advised that the aircraft came down North of Hamburg. Awaiting confirmation of this.

According to the latest update (2019 - 1943 Part 2) of the Nachtjagd Combat Archive by Theo Boiten it is claimed a 'possible' by Uffz. Hans Krepp of 1./NJG3 with the aircraft coming down at 00:24 hrs over Sankt Peter-Ording.

(1) Oberst. (Posth) Helmut Lent went on to claim 102 night fighter kills and a further 8 kills before on the 7th October 1944 he died after suffering injuries sustained during a crash landing on the 5th October 1944 during a crash landing in his Ju 88 G-6 at Paderborn Airfield following engine failure and subsequent collision with a high tension cable.

His crew were rescued - injured from the crash.

Walter Kubisch (radio operator) and Hermann Klöss (2nd radio operator) died the same day, Werner Kark (War correspondent and Air/Gnr) died the next morning.
