The bombing of Dresden was a British-American aerial bombing attack on the city of Dresden, the capital of the German state of Saxony, during World War II.
In four raids between 13th and 15h February 1945, 722 heavy bombers of the British Royal Air Force (RAF) and 527 of the United States Army Air Forces (USAAF) dropped more than 3,900 tons of high-explosive bombs and incendiary devices on the city.
The bombing and the resulting firestorm destroyed more than 1,600 acres (6.5 km2) of the city centre.
An estimated 22,700 to 25,000 people were killed.
Three more USAAF air raids followed, two occurring on 2nd March aimed at the city's railway marshalling yard and one smaller raid on 17th April aimed at industrial areas.
