World War I The 3rd Regiment of Infantry was called into Federal service on 25 July 1917 after the
United States' entry into World War I. Drafted into service on 5 August, it became the 120th Infantry Regiment of the 30th Division on 12 September, while the 2nd Regiment of Infantry became the
119th Infantry. With the 30th Division, the 120th fought in the
Somme Offensive, the
Ypres-Lys offensive, and the Flanders campaign during the war. Both the 119th and 120th were demobilized at
Camp Jackson, South Carolina on 17 April 1919, preceding the demobilization of the division headquarters there on 7 May.
Interwar period The 120th Infantry arrived at the
port of Charleston, South Carolina, in April 1919 on the troopship
USS Martha Washington and was demobilized on 17 April 1919 at Camp Jackson, South Carolina. Per the
National Defense Act of 1920, it was reconstituted in the National Guard in 1921, assigned to the 30th Division, and allotted to the state of North Carolina. The regiment was reorganized on 8 November 1921 by redesignation of the 1st Infantry, North Carolina National Guard (organized 1919–20; headquarters organized 2 May 1921 and federally recognized at
Graham, North Carolina) as the 120th Infantry. The regimental headquarters was relocated on 25 January 1937 to
Raleigh, North Carolina. The regiment, or elements thereof, was called up to perform the following state duties: riot control for a race riot in
Goldsboro, North Carolina, in 1920; riot control for
the railroad strike throughout North Carolina, 17 July–31 August 1922; riot control for elections at
Mayodan, North Carolina, in 1923; riot control for textile workers’ strike at
Kannapolis, North Carolina, in 1923; riot control for workers’ strike at
Pittsboro, North Carolina, in 1927; elements of 2nd and 3rd Battalions performed riot control for textile workers’ strike at
Gastonia, North Carolina, in April 1929; riot control for textile workers’ strike in
Burlington, North Carolina and
Alamance County, North Carolina, 15–25 September 1934; riot control for textile workers’ strike at
Reidsville, North Carolina, in September 1935. The regiment conducted annual summer training most years at Camp Glenn, North Carolina, near
Morehead City, and some years at Camp Jackson, South Carolina.
World War II As a result of
World War II, the regiment was inducted into Federal service at Raleigh on 16 September 1940. With the 30th Division, it fought in the
Normandy campaign, the
Northern France Campaign, the
Rhineland Campaign, the
Ardennes-Alsace Campaign, and the
Central Europe Campaign. The 2nd Battalion and Company K received a
Distinguished Unit Citation and
Croix de Guerre with Palm for their actions in the
Mortain counterattack, while the 1st Battalion received a DUC for the advance from Duffescheide to Euchen, Germany. After the end of the war, the regiment was inactivated at Fort Jackson, South Carolina, on 24 November 1945.
Cold War Postwar, the 120th Infantry was reorganized with the 30th Infantry Division in the North Carolina Army National Guard under the command of
Shelby attorney Colonel Peyton McSwain, with its headquarters Federally recognized at
Reidsville on 22 April 1947. Its previous 1st and 3rd Battalions were consolidated with the 119th Infantry Regiment. Through 1947 and 1948, the remainder of the regiment was reorganized and Federally recognized, based at armories in western North Carolina. Support units included a Service Company at
Asheville, a Heavy Mortar Company at
Leaksville, a Heavy Tank Company at
Waynesville, and a Medical Company at
Mocksville. The 1st Battalion, with headquarters at
Mount Airy, included Company A at
Burlington, Companies B and D at
Winston-Salem, and Company C at
Lexington. The 2nd Battalion, headquartered at
Asheboro, included Company E at
Concord, Company F at
Albemarle, Company G at
Salisbury, and Company H at
Hickory. The 3rd Battalion, headquartered at
Kings Mountain, included Company I at
Newton, Company K at
Gastonia, Company L at
Morganton, and Company M at
Shelby. The regiment participated in its first postwar summer training at
Fort Bragg between 11 and 25 July 1948 with most of the 30th Division. After the camp it was estimated at 32% combat readiness by the senior army instructor of the North Carolina National Guard, which meant that in event of war it would not be combat ready for several months. The 1949 summer training was held at Fort Jackson between 14 and 28 August with the division, and the senior army instructor reported that, with 90 percent of the officers and 65 percent of the non-commissioned officers veterans of World War II, the regiment would be ready for combat in at least eight months in event of war. Morganton school superintendent and 3rd Battalion commander Lieutenant Colonel Maston S. Parham was promoted to colonel and became regimental commander on 30 August 1950 following the retirement of McSwain. A 1954 reorganization of the 30th Infantry Division that made it an entirely North Carolina-manned force resulted in the 2 November promotion of Parham to assistant division commander and his replacement by Morganton Colonel Howell J. Hatcher. To bring the division up to strength, a new
139th Infantry Regiment was organized from existing units of the division, resulting in the redesignation of companies of the 120th and the conversion and organization of new units to bring the 120th back up to strength. The regimental Headquarters and Headquarters Company (HHC), the Heavy Mortar Company, and the HHC of 2nd Battalion transferred to the 139th, along with Companies A, F, and C, which became Companies E, F, and G, of the 139th, respectively. Company L of the 120th was redesignated as the regimental HHC, Battery A of the
112th Field Artillery Battalion (FAB) at
Forest City was converted into the Heavy Mortar Company, and Companies G, K, I, and M became Companies C, F, G, and K, respectively. Battery B of the 112th FAB at
Spindale was converted into the new Company M. The new Company L at
Hendersonville activated on 8 February 1955, followed by 2nd Battalion HHC at
Kannapolis on 15 February, Company I at
Sylva on 14 April, and Company A at
Elkin on 7 June. ==Recent history==
