The 1943 Bombing of Hamburg was the Allied fire bombing of the German city of Hamburg during World War II. Codenamed Operation Gomorrah, it was conducted by the RAF Bomber Command and the US Eighth Air Force, from July 24 to August 1, 1943. The death toll of the Bombing of Hamburg rose to 42,600 with 37,000 wounded as more than a million people fled the inferno created by the Allied incendiary bombs.
Operation Gomorrah began at 00:57 hours on July 24, 1943, by British Lancaster aircraft from RAF Bomber Command. This first bombing raid lasted one hour. A second daylight attack, carried out by US Eighth Air Force, began at 16:40 hours on the same day. A third raid was conducted on the morning of July 26; it was a light attack due to a severe thunderstorm and high winds over the North Sea. On the night of July 27, shortly before midnight, 739 aircraft bombed Hamburg. On July 29, the city of Hamburg was again attacked by a force of 700 bombers. The incendiary bombing concentrated in one area set off an inferno with winds of up to 150 mph, reaching temperatures of 800 °C (1,500 °F) and altitudes in excess of 1,000 feet, incinerating more than eight square miles of the city. Asphalt streets burst into flame, as fuel oil from damaged and destroyed ships, barges, and storage tanks was ignited as well.
