Cause

Following the Japanese attack on Pearl Harbor on December 7, 1941, the United States sought a retaliatory strike against the Japanese mainland. Lieutenant Colonel James Doolittle planned the operation to demonstrate American resolve and striking capability, despite the logistical challenge of launching land-based bombers from an aircraft carrier far from Japan.

Event

On April 18, 1942, sixteen B-25B Mitchell bombers took off from the USS Hornet in the Pacific Ocean without fighter escorts and struck Tokyo and other targets on Honshu. After dropping their bombs, the crews flew westward intending to land in China; most aircraft were lost in crashes, and eight airmen were captured by Japanese forces.

Consequence

Though physical damage was minimal, the raid shook Japanese confidence in home island defense and boosted American morale. It accelerated Admiral Yamamoto's plans to attack Midway Island, leading to the IJN's decisive defeat there. Japan also launched the brutal Zhejiang-Jiangxi campaign in China in reprisal, causing widespread civilian suffering.
