Operation Hydra was an attack by RAF Bomber Command on a German scientific research centre at Peenemünde on the night of 17/18 August 1943. Group Captain John Searby, commanding officer of No. 83 Squadron RAF, commanded the operation, the first time that Bomber Command used a master bomber to direct the attack of the main force. Hydra was the first operation against the German V-weapon programme, a campaign later known as "Crossbow".^[3] The British lost 40 bombers and 215 aircrew, and several hundred enslaved workers in the nearby Trassenheide forced labour camp were killed. The Luftwaffe lost twelve night-fighters and about 170 German civilian personnel were killed, including two V-2 rocket scientists. Assessments of the raids effectiveness vary; the United States Strategic Bombing Survey (1945) called the raid "not effective", while in 2006 the historian Adam Tooze judged that it had been highly successful.
