In 1921 the 1st Cavalry Brigade was renamed the 56th Cavalry Brigade and assigned to the 23rd Cavalry Division as part of the Army’s post-World War I reorganization of the National Guard. Soldiers of the 56th Cavalry were called out several times to quell civil disturbances, including: the Longview Race Riot of 1919; the Galveston Longshoreman's Strike of 1920; the Mexia and BorgerOil Field Booms of 1922 and 1929; the booms in the East Texasoil fields in 1931 and 1932; and the response following a hurricane in 1932. Wolters commanded troops on state active duty so often that he published a manual on use of the National Guard in reestablishing law and order following riots and natural disasters. In 1929 the 111th Cavalry Regiment was made a separate organization, and the newly organized 124th Cavalry Regiment was added to the 56th Cavalry Brigade, making it a completely Texas National Guard organization.
In 1940 the 56th Cavalry Brigade headquarters was federalized for World War II. The 56th was the last cavalry brigade in the United States to have horses, and in 1944 the headquarters was reorganized as the 56th Cavalry Reconnaissance Troop. The new unit was demobilized in November, 1945, following the end of World War II. The brigade headquarters and re-organized reconnaissance troop did not deploy overseas or see combat, but the 112th and 124th Cavalry, the regiments previously assigned to the 56th Cavalry Brigade, did serve overseas.
Post-World War II
The post-World War II reorganization of the National Guard included the creation of several armored divisions, among them the 49th Armored Division in Texas. The 56th Cavalry Reconnaissance Troop was reorganized as Headquarters, and Headquarters Company, Combat Command A, 49th Armored Division and stationed in Fort Worth. In October, 1961 the unit was federalized for during the Berlin crisis and trained at Fort Polk and other locations before being demobilized. The headquarters of Combat Command A was reorganized in 1963 and the new unit was designated Headquarters and Headquarters Company, 2nd Brigade, 49th Armored Division. In 1968 the 2nd Brigade’s headquarters was re-designated as Headquarters, 49th Armor Group when the 49th Armored Division was broken up. The group controlled the 2nd and 3rd Battalions of the 112th Armor. In 1971 another reorganization resulted in the renaming of the 49th Armor Group’s headquarters as Headquarters, 49th Armored Brigade. When the 49th Armored Division was reformed in a 1973 reorganization, the brigade headquarters became that of the 2nd Brigade, 49th Armored Division.
The Army’s conversion to modular brigades from 2004 to 2006 included the 56th Brigade’s organization as an Infantry Brigade Combat Team. Its task organization includes:
