In February 1945, Prague suffered several bombing raids by the US Army Air Forces. 701 people were killed, more than 1,000 people were injured and some buildings, factories and historical landmarks (Emmaus Monastery, Faust House, Vinohrady Synagogue) were destroyed. Many historic structures in Prague, however, escaped the destruction of the war and the damage was small compared to the total destruction of many other cities in that time. According to American pilots, it was the result of a navigational mistake. In March, a deliberate raid targeted military factories in Prague, killing about 370 people.
