Activated on 7 December 1942 in Providence, Rhode Island, the XIII Corps fought for 180 days in the European Theater of Operations, fighting from the Netherlands to the Elbe River. It was first activated under the command of then-Major General Emil F. Reinhardt, but would be commanded in combat by Major General Alvan C. Gillem, Jr. as a subordinate unit to Ninth U.S. Army, it under the command of the Allied 21st Army Group. In November 1944, the XIII Corps pierced the Siegfried Line and pushed to the Roer River. On 23 February 1945, the corps routed Third Reich forces in the Cologne Plain and made a dash for the Rhine on 31 March of that year. In 180 days of combat, the corps had progressed as far as the Elbe River to the vicinity of Tangermunde, bringing it to approximately 50 miles from Berlin, the closest American forces would come to the enemy capital before V-E Day. In total, the corps fought across more than 300 miles of enemy territory and captured more than 247,000 prisoners, as well as taking key cities, such as Viersen, Krefeld, Moers, Homburg, Münster, and Hannover. In the month following V-E Day, units from the corps were redeployed. Corps headquarters would eventually find its way to Camp Cooke, California, where on 25 September 1945, XIII Corps was inactivated. The corps was subsequently active as part of the Regular Army from 1958 until 1970 at Fort Devens, Massachusetts.
