XIV Corps (United States)

XIV Corps (United States) was a corps of the United States Army originally constituted in 1933 and most notably active during World War II in the Pacific Theater. It played a pivotal role in the Guadalcanal Campaign and subsequent operations in the Solomon Islands and the Philippines. The corps was later reactivated during the Vietnam War as part of United States Army Pacific before its final inactivation in 2013.

History

The XIV Corps was first constituted in the Regular Army on 1 October 1933, though it remained a paper formation for nearly a decade. Its initial activation was part of the United States Army's interwar organizational structure, headquartered at Fort Leavenworth. The corps was not deployed for combat until the outbreak of World War II, when it was hastily organized and shipped to the Pacific Ocean Areas in 1942. Following its distinguished service in the Pacific War, the corps was inactivated in 1946 at Camp Anza in California. It was reactivated in 1968 at Fort Lewis as part of the United States Army Pacific command structure, serving primarily as a strategic headquarters during the Vietnam War and the Cold War before its final inactivation ceremony at Fort Shafter in 2013.

World War II

XIV Corps saw its first and most significant combat after arriving in the South Pacific Area in late 1942. It assumed command of all United States Army forces on Guadalcanal in December, taking over from the 1st Marine Division during the critical final stages of the Guadalcanal Campaign. Under the command of Major General Alexander Patch, the corps, comprising the Americal Division and the 25th Infantry Division, successfully defeated remaining Imperial Japanese Army forces, securing the island by February 1943. The corps later participated in the Solomon Islands campaign, including the Battle of Munda Point on New Georgia. In 1945, XIV Corps was a key component of General Douglas MacArthur's Sixth United States Army during the liberation of the Philippines. It conducted major amphibious assaults at Lingayen Gulf and fought in the intense battles for Manila and the ZigZag Pass.

Post-World War II

After Victory over Japan Day, XIV Corps performed occupation duty in Japan as part of the Eighth United States Army. It was inactivated in January 1946. The corps remained on the inactive list until its reactivation on 1 September 1968 at Fort Lewis, Washington. For the next four decades, it served as a component headquarters of United States Army Pacific, providing command and control for army forces in the Pacific Command area of responsibility. During this period, its subordinate units included the 25th Infantry Division in Hawaii and the 2nd Infantry Division in South Korea. The corps was inactivated for the final time on 6 June 2013 during a ceremony at its headquarters on Fort Shafter.

Campaigns and decorations

XIV Corps earned several campaign streamers and unit awards for its service. Its World War II campaign credits include Guadalcanal, Northern Solomons, and Luzon. The corps headquarters was awarded the Philippine Presidential Unit Citation for its actions during the 1945 campaign. Individual soldiers within the corps received numerous decorations, including the Medal of Honor, Distinguished Service Cross, and Silver Star. The corps' shoulder sleeve insignia, featuring a blue shield with a white sword, was originally approved in 1942 and became a symbol of its "Jungleers" nickname earned in the South Pacific.
