General Dornberger, von Braun, and Dr. Steinhof briefed Hitler in his Wolf's Lair. Also in attendance were Speer, Wilhelm Keitel, and Alfred Jodl. The briefing included von Braun narrating a movie showing the successful launch on 3 October 1942, with scale models of the Channel coast firing bunker, and supporting vehicles, including the . Hitler then gave Peenemünde top priority in the German armaments program stating, "Why was it I could not believe in the success of your work? if we had had these rockets in 1939 we should never have had this war..." Hitler also wanted a second launch bunker built. Saur planned to build 2,000 rockets per month, between the existing three factories and the Nordhausen Mittelwerk factory being built. However, alcohol production was dependent upon the potato harvest. A production line was nearly ready at Peenemünde when the Operation Hydra attack occurred. The main targets of the attack included the test stands, the development works, the Pre-Production Works, the settlement where the scientists and technicians lived, the Trassenheide camp, and the harbor sector. According to Dornberger, "Serious damage to the works, contrary to first impressions, was surprisingly small." Work resumed after a delay of four to six weeks, and because of camouflage to mimic complete destruction, there were no more raids during the next nine months. The raid resulted in 735 lives lost, with heavy losses at Trassenheide, while 178 were killed in the settlement, including Dr. Thiel, his family, and Chief Engineer Walther. The Germans eventually resulted production to the underground Mittelwerk in the Kohnstein where 5,200 V-2 rockets were built with the use of forced labour. Launch sites After the Operation Crossbow bombing, initial plans for launching from the massive underground Watten, Wizernes and Sottevast bunkers or from fixed pads such as near the Château du Molay were dismissed in favour of mobile launching. Eight main storage dumps were planned and four had been completed by July 1944 (the one at Mery-sur-Oise was begun during August 1943 and completed by February 1944). The missile could be launched practically anywhere, roads running through forests being a particular favourite. The system was so mobile and small that only one was ever caught in action by Allied aircraft, during the Operation Bodenplatte attack on 1 January 1945 near Lochem by a USAAF 4th Fighter Group aircraft, although Raymond Baxter described flying over a site during a launch and
