The last major attack of the month followed on March 24, this time a daily attack by 262 aircraft of the American Air Force. In total, more than 1,500 people were killed in the attacks in March 1944. The main reason for the fact that the number of victims was not higher than in other cities was that, since the summer of 1940, the solidly built cellars of the old town houses had been interconnected. An emergency exit at the Fountain of Justice on the Römerberg alone saved around 800 people.
