Columbia Army Air Base was a World War II United States Army Air Forces base. It was primarily used for advanced combat training of B-25 Mitchell medium bomber units and replacement pilots.

The Doolittle Raid, also known as Doolittle's Raid, as well as the Tokyo Raid, was an air raid on 18 April 1942 by the United States on the Japanese capital Tokyo and other places on Honshu during World War II. It was the first American air operation to strike the Japanese archipelago. Although the raid caused comparatively minor damage, it demonstrated that the Japanese mainland was vulnerable to American air attacks. It served as an initial retaliation for the December 7, 1941, attack on Pearl Harbor, and provided an important boost to American morale. The raid was planned by, led by, and named after Lieutenant Colonel James Doolittle. It was one of six American carrier raids against Japan and Japanese-held territories conducted in the first half of 1942.
