An Alabama regiment was formed in 1836 to defend Fort Foster in Florida. The same unit, designated the 1st Alabama Volunteers ten years later, served in the Mexican War. Mustered again on May 4, 1861, as the 4th Alabama Infantry Regiment, it fought in every major battle in the Eastern Theater of the Civil War. The 4th distinguished itself in the Battle of Manassas, the first major battle of the war, when it plugged a gap in Confederate lines beside Brig. Gen. T. J. Jackson’s brigade and repulsed several Union regiments; in that fight, Jackson acquired the name “Stonewall.” The 4th Alabama trained here in 1916 at Vandiver Park, later named Camp Sheridan, for Mexican Border service. Designated the 167th Infantry Regiment in 1917, it returned from the border to train here, then fought in France during World War I with Douglas MacArthur’s brigade in the 42nd “Rainbow” Division. The 167th was at the front longer than any other U.S. regiment. In 1923 it was assigned to the 31st Infantry “Dixie” Division. Activated in November 1940, the 31st Division fought in several major campaigns in the Pacific Theater of World War II. The division was called up for the Korean War in January 1951.
