High Quality Content by WIKIPEDIA articles! During World War II, the German city of Heilbronn was bombed many times by both the British and the Americans. The largest air-raid occurred on December 4, 1944, but there were many previous attacks targeted at Heilbronn that were almost as damaging. These raids continued until the end of World War II; in 1944, Heilbronn was attacked to a point where alarms in the city were almost daily. Altogether, an estimated 7,000 inhabitants lost their lives during the bombing.
