Bomber Command War Diary
12 March 1945
1,108 aircraft – 748 Lancasters, 292 Halifaxes, 68 Mosquitos attacked Dortmund. This was another new record to a single target, a record which would stand to the end of the war. 2 Lancasters lost. Another record tonnage of bombs – 4,851 – was dropped through cloud on to this unfortunate city. The only details available from Dortmund state that the attack fell mainly in the centre and south of the city. A British team which investigated the effects of bombing in Dortmund after the war says that, ‘The final raid … stopped production so effectively that it would have been many months before any substantial recovery could have occurred’.
