On July 14, 1945 and July 15, 1945 thirty B-29 Superfortress bombers dropped 889 tons of E-46 500 lbs incendiary cluster bombs and 500 lbs T4E4 fragmentation cluster bombs into Sapporo at midday during two separate air raids. In the resulting firestorm 190 civilians were killed, 6,788 were injured, 78,000 others remained homeless, and many structures burned. A total of 17.5 percent of Sapporo was destroyed during the Pacific War.
Something does not add up. 30 B-29s drop 889 tons of bombs = 30 tons each if it is a single raid by 30 aircraft or 15 tons each if two separate raids by 30 aircraft. 15 tons each on the longest raid of the war?
30 aircraft do not create a firestorm anywhere and are unlikely to render 78000 people homeless, even in a Japanese city of that period
