Operation meetinghouse was a bombing attack by the United States against Japan on the night between the 9th and 10th of March 1945. American bombers dropped fire bombs without a specific target on the Japanese city of Tokyo. These fire bombs created a huge firestorm which killed over 100,000 people and destroyed the homes of about 1 million more people. It is notable for being the most deadly attack from the air in world history, with the Atomic bombings of Hiroshima and Nagasaki after it, as well as a change in strategy for the United States, which had previously only attacked from the air during the day, focusing on specific buildings.
