The Firebombing of Tokyo continues

On March 10, 1945, 300 American bombers continue to drop almost 2,000 tons of incendiaries on Tokyo, Japan, in a mission that had begun the previous day. The attack destroyed large portions of the Japanese capital and killed 100,000 civilians.

In the closing months of the war, the United States had turned to incendiary bombing tactics against Japan, also known as “area bombing,” in an attempt to break Japanese morale and force a surrender. The firebombing of Tokyo was the first major bombing operation of this sort against Japan.

Early in the morning, the B-29s dropped their bombs of napalm and magnesium incendiaries over the packed residential districts along the Sumida River in eastern Tokyo. The conflagration quickly engulfed Tokyo’s wooden residential structures, and the subsequent firestorm replaced oxygen with lethal gases, superheated the atmosphere, and caused hurricane-like winds that blew a wall of fire across the city. The majority of the 100,000 who perished died from carbon monoxide poisoning and the sudden lack of oxygen, but others died horrible deaths within the firestorm, such as those who attempted to find protection in the Sumida River and were boiled alive, or those who were trampled to death in the rush to escape the burning city. As a result of the attack, 10 square miles of eastern Tokyo were entirely obliterated, and an estimated 250,000 buildings were destroyed.

During the next nine days, U.S. bombers flew similar missions against Nagoya, Osaka, and Kobe. In August, U.S. atomic attacks against Hiroshima and Nagasaki finally forced Japan’s hand.
