Now the bases were available to do the same to Japan. Quickly it became apparent that the planes could not sustain operations in China and were moved to the Marianas. The precision targets were not successful, partly due to the lack of fighter cover and partly due to the construction of Japanese factories, refineries and military institutions. Unlike Germany, which required tons of high explosive for each attack, the high explosive from high altitude did not have the same effect on the paper and wood structures predominant in Japan.
When Curtiss LeMay arrived and took command in January 1945, he ordered a switch from high altitude high explosive precision daylight attacks to night area bombing with a mixture of incendiaries and antipersonnel weapons. This prevented the firefighters from putting out the fires, which spread wildly.
From March 1945 through the end of the war, many Japanese cities were subjected to area bombing with incendiaries. Tokyo, Osaka, and many other cities were burned out by firestorms that reached over 1000 degrees Fahrenheit. The bombings may have killed as many as 500,000 people.
After the atomic attack of August 9, hundreds of B-29s hit the rubble of Tokyo again. On August 15, the last battle of the Pacific War was between a flight of B-32 Dominators, another kind of heavy bomber, and Japanese naval fighters. That day the Emperor proclaimed the armistice. The war was over.
