Dresden is the capital city of the German state of Saxony and its second most populous city, after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area (following Berlin, Hamburg and Cologne), and the third most populous city in the area of former East Germany, following Berlin and Leipzig. Dresden’s urban area comprises the towns of Freital, Pirna, Radebeul, Coswig and Heidenau and has around 790,000 inhabitants. The Dresden metropolitan area has approximately 1.34 million inhabitants. Dresden is the second largest city on the River Elbe after Hamburg. 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 13 and 15 February 1945, 772 heavy bombers of the 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 2 March aimed at the city’s railway marshalling yard and one smaller raid on 17 April aimed at industrial areas. Immediate German propaganda claims following the attacks and postwar discussions of whether the attacks were justified have led to the bombing becoming one of the moral causes célèbres of the war. A 1953 United States Air Force report defended the operation as the justified bombing of a strategic target, which they noted was a major rail transport and communication centre, housing 110 factories and 50,000 workers in support of the German war effort. Several researchers claim that not all of the communications infrastructure, such as the bridges, were targeted, nor were the extensive industrial areas which were located outside the city centre. Critics of the bombing have asserted that Dresden was a cultural landmark while downplaying its strategic significance, and claim that the attacks were indiscriminate area bombing and not proportionate to the military gains. Some have claimed that the raid constituted a war crime. Some people refer to the bombing as a mass murder, calling it “Dresden’s Holocaust of bombs”. Full HD.
