The German city of Mannheim in the state of Baden-Württemberg saw bombing during World War II from December 1940 until the end of the war. Mannheim saw over 150 air raids. As part of Operation Abigail Rachel, the "first deliberate terror raid" on Germany took place on 16 December, although with poor effect even though one hundred tonnes of explosives and 14,000 incendiaries were dropped on Mannheim. This was the start of a British drift away from precision attacks on military targets and towards area bombing attacks on whole cities.
