440 aircraft - 263 Halifaxes, 160 Lancasters, 17 Mosquitos - of Nos 4,6 and 8 Groups dispatched to Hamburg. 3 Halifaxes and 3 Lancasters lost. This attack was intended for the shipyard areas but partial cloud caused the raid to become dispersed. Some damage was probably caused to the shipyards but, as an American raid on the yards had taken place a few hours earlier, damage seen in photographs could not be allocated between the two forces. This was the last major Bomber Command raid of the war on Hamburg.
