XIV Corps was a corps-sized formation of the United States Army, originally constituted on 1 October 1933 in the Organized Reserves. The history of XIV Corps in World War II dates from December 1942. Then, under Major General Alexander Patch, the XIV Army Corps directed the American 23rd Infantry Division and 25th Infantry Divisions, the 2nd Marine Division, and the 147th Infantry Regimental Combat Team in the final drive that expelled the Japanese from Guadalcanal early in February 1943. The 70th Coast Artillery Regiment (Anti-Aircraft) landed on 23 May 1943. From air fields guarded by the XIV Army Corps, Allied aircraft began the neutralization of the enemy's vital Munda airfields on New Georgia.
