The Bombing of Dresden by the British Royal Air Force (RAF) and United States Army Air Force (USAAF) between February 13 and February 15, 1945 were war crimes committed by the Allies of World War II. In four raids, 1,300 heavy bombers dropped more than 3,900 tons of high-explosive bombs and incendiary devices on the city, the Baroque capital of the German state of Saxony. The resulting firestorm destroyed 39 square kilometres (15 sq mi) of the city centre. 
Between October 7, 1944 and April 17, 1945 Dresden was bombed by an estimated 2,500 bombers. During the evening of February 13 an 14, 1945, Dresden was attacked by 772 English and 311 American bombers. According to calculations by the British historian David Irving the total amount of bombs dropped on Dresden was 650,000 tons (fire bombs). The Allies used the first generation of incendiary petroleum bombs which caused massive fire storms. The fires were so intense people standing in the street was sucked into the burning buildings. With accounts of up to 350,000 victims, the bombing of Dresden would be the single most devastating war crime atrocity of World War II.
