The Kassel World War II bombings were a set of Alliedstrategic bombing attacks which took place from February 1942 to March 1945. In a single deadliest raid on 22–23 October 1943, 150,000 inhabitants were bombed-out, at least 10,000 people died, the vast majority of the city center was destroyed, and the fire of the most severe air raid burned for seven days. The US First Armycaptured Kassel on 3 April 1945, where only 50,000 inhabitants remained, versus 236,000 in 1939.
547 aircraft used H2S radar; the main weight of bombs fell on the western suburbs and outlying towns and villages.
22/23 October 1943
569 bombers dropped more than 1,800 tons of bombs (including 460,000 magnesium fire sticks) in a concentrated pattern. For deception, the attack used Operation Corona radio spoofing and a Frankfurt diversionary raid. The blaze caused a minor firestorm similar in nature to that at Hamburg. Damage to the main telephone exchange and the city's water pipes hindered firefighting efforts.
