At the beginning of World War II the 10th Cavalry was relegated to caretaker duties at Fort Leavenworth, Kansas. In 1942 the regiment was moved to Camp Lockett, California, replacing the 11th Cavalry in its duties as the southern defense of the Western Defense Command, under LTG DeWitt. 153 NCOs of this regiment would later be assigned to the newly organized 28th Cavalry Regiment forming its cadre, and filling out the 4th Cavalry Brigade, which would remain in existence after the deactivation of the 2nd Cavalry Division, and its subsequent reactivation. In the summer of 1943, the 10th and 28th Cavalry Regiments fought wildfires in the Cleveland National Forest. In 1944, the entire 2nd Cavalry Division was shipped out to Oran, North Africa; where it disembarked and was deactivated on 9 March 1944. Although trained as combat soldiers, the soldiers of this regiment, and other regiments of the 2nd Cavalry Division were reorganized as combat support and combat service support units. Some would see combat as replacement soldiers of the 92nd Infantry Division.. Where was the 10th Cavalry regiment first, Camp Lockett or Cleveland National Forest?
