The Bulgarian capital of Sofia suffered a series of Allied bombing raids during World War II, from late 1943 to early 1944. United Kingdom and the United States declared a token war on Bulgaria on 13 December 1941. The Southern Italy-based Allied air forces extended the range of their strategic operations to include Bulgaria and other Axis allies in 1943.
The most severe bombing of Sofia ever occurred on March 30, 1944. Some 370 American heavy bombers flew over Sofia destroying 3575 buildings. Over 3000 high explosive bombs and 30000 incendiary bombs were used. There were 139 people killed. The casualty figures were relatively modest due to preliminary evacuation of the civilians. The targets of the bombing were neither military installations, nor armed forces, but historical downtown Sofia.
