"On the 13th February 1945, 773 Avro Lancasters bombed Dresden. During the next two days the USAAF sent over 527 heavy bombers to follow up the RAF attack. Dresden was nearly totally destroyed. As a result of the firestorm it was afterwards impossible to count the number of victims. Recent research suggest that 135,000 were killed but some German sources have argued that it was over 250,000. Whatever the figure, it was probably greater than the 51,509 British civilians killed by the Luftwaffe during the whole of the Second World War and the 70,000 immediate deaths at Hiroshima after the dropping of the first atom bomb on 6th August 1945."
