The air attack of Friday, 19 September was particularly brutal. It was the heaviest air raid Leningrad would suffer during the war, as 276 German bombers hit the city killing 1,000 civilians. Many of those killed were recuperating from battle wounds in hospitals that were hit by German bombs. Six air raids occurred that day. Five hospitals were damaged in the bombing, as well as the city's largest shopping bazaar. Hundreds of people had run from the street into the store to take shelter from the air raid.
