3D Armored Cavalry Regiment (United States) - World War I and II

World War I and II

In August 1917, the Regiment was alerted for overseas duty. Arriving in France in November, the Regiment was broken up and operated three major remount depots until the war’s end. The only actual 3d Cavalry unit to see action in World War I was K Troop, which was detached from the 3rd Squadron and participated in the last three engagements prior to the Armistice of 11 November 1918. After World War I, the Regiment deployed back to the United States and executed a garrison mission until the beginning of World War II. In July 1932 Major George S. Patton-under order of Douglas MacArthur-led the 3d against the Bonus Army in Washington D.C.

In January 1943, the Regiment was re-designated the as the 3d Cavalry Group (Mechanized). The 3d Cavalry Group arrived in France in 1944 and was attached to XX Corps. On 17 November 1944, after numerous fierce battles, the 3d Cavalry Group Troopers became the first to cross into Germany.
