Editing 2nd Infantry Division (United States) (section)

===Interwar years===

The 2nd Division arrived at Hoboken, [[New Jersey]], on 3 August 1919 after completing 8 months of occupation duty near [[Koblenz]], [[Neuwied|Heddesdorf]], and [[Dierdorf]], [[Germany]]. It moved to [[Camp Mills]], [[New York (U.S. state)|New York]], where all emergency period personnel were discharged from the service, and the 4th Marine Brigade was relieved from assignment to the division. It proceeded to [[Camp Travis (Texas)|Camp Travis]], in [[San Antonio, Texas]], on 16 August 1919 where it remained until Camp Travis was absorbed into Fort Sam Houston in 1922. The 4th Infantry Brigade (consisting of the 1st and 20th Infantry Regiments) was assigned to replace the 4th Marine Brigade in the division structure, and was activated in October 1920 at Camp Travis. The division was allotted to the [[Eighth Corps Area]] and the [[VIII Corps (United States)|VIII Corps]] in 1921. The 2nd Division was the most combat-ready division stationed in the continental United States during most of the interwar period, given that the majority of the unit was stationed at a single post and the division headquarters staff was not allowed to atrophy like those of the 1st or 3rd Divisions, the other two nominally active stateside Regular Army divisions. 

During the early post-World War I period, the division’s time was spent rebuilding and training on a limited scale. The slow pace left time for the division to assist Hollywood in making movies about the Army. Division units participated in [[Metro-Goldwyn-Mayer]]’s movie ''[[The Big Parade]]'' in May and June 1925 and in ''[[Wings (1927 film)|Wings]]'' in April 1926. By 1926, however, maneuver training of divisional units was becoming more frequent, leaving little time for movies. The maneuvers generally took place in May, before the division’s units assisted the training of [[United States Army Reserve|Organized Reserve]] units, [[Citizens Military Training Camps]] (CMTC), and ROTC cadets during the summer. Typically, the division would deploy to [[Camp Bullis]], Texas, or areas west of San Antonio, and perform field training, usually at company and battalion level. The division deployment would culminate in brigade-versus-brigade maneuvers near the end of the field training period. 

After transfer of the 4th Infantry Brigade to [[Fort D. A. Russell (Wyoming)|Fort D.A. Russell]], [[Wyoming]] (later renamed [[Francis E. Warren Air Force Base|Fort Francis E. Warren]]), in 1927, the [[1st Cavalry Division (United States)|1st Cavalry Division]]'s [[1st Brigade Combat Team, 1st Cavalry Division (United States)|1st Cavalry Brigade]] began to road-march over from [[Fort Clark, Texas]], to participate in combined arms maneuvers each May. Once the division maneuvers were complete, the division shifted to training the Reserve components. The 3rd Infantry Brigade usually trained Reserve officers of the [[90th Infantry Division (United States)|90th Division]], Infantry CMTC, and ROTC cadets. Units of the 2nd Field Artillery Brigade trained the artillery officers of the 90th Division, the XVIII Corps, and several General Headquarters Reserve (GHQR) artillery units in the Eighth Corps Area. After transferring to Fort Francis E. Warren, the 4th Infantry Brigade conducted their maneuver training at the Pole Mountain Military Reservation where they also trained their affiliate Reserve units of the [[104th Infantry Division (United States)|104th Division]]. In 1936, the division participated in the Third Army [[military exercise|command post exercise]] (CPX) at Camp Bullis to prepare army, corps, and division staffs for future large-scale army maneuvers. The next major training event for the division came in September 1937 when it participated in the Provisional Infantry Division (PID) tests at Camp Bullis. The “Indianhead” Division was temporarily reorganized with three regiments to test the concept of the “triangular” division. The exercise was apparently very successful as further tests were called for after analysis of the results by Army planners. The following year, units of the Eighth Corps Area including the 2nd Division were assembled at Camp Bullis for the Third Army maneuvers. In January 1939, the division was reorganized for the second time as a triangular division, this time for the Provisional 2nd Division (P2D) tests. These tests finalized the decision to adopt the new triangular organization for Regular Army divisions. As a result, in October 1939, the division’s 4th Infantry Brigade was disbanded, the 1st and 20th Infantry Regiments were relieved from assignment, and the 38th Infantry Regiment was assigned to the division to make its transition to the triangular concept complete. 

In May 1940, the “Indianhead” Division deployed to the vicinity of [[Horton, Texas]], to train under the new organization in preparation for the next Third Army maneuver. The 1940 Third Army maneuvers were held in west-central [[Louisiana]] in August 1940 and were primarily performed with the Regular Army and National Guard divisions stationed in the Fourth and Eighth Corps Areas. After the exercises in Louisiana, the “Indianhead” Division returned to Fort Sam Houston. The following June, the division moved to [[Brownwood, Texas]], to participate in the VIII Corps maneuver held there that month. In August 1941, the division, now redesignated as the 2nd Infantry Division, returned to the Louisiana Maneuver Area for the [[Louisiana Maneuvers|GHQ maneuvers between the Second and Third Armies]], after which it returned to its home station.<ref>{{cite book|last=Clay|first=Steven E.|date=2010|title=U.S. Army Order of Battle, 1919-1941, Volume 1.

On 27 July 1942, the division was again transferred to the Louisiana Maneuver Area, remaining there until 22 September 1942, whereupon the formation again returned to Fort Sam Houston. It then moved to [[Camp McCoy]] at [[Sparta, Wisconsin|Sparta]], Wisconsin, on 27 November 1942. Four months of intensive training for winter warfare followed. In September 1943 the division received its staging orders, and moved to the [[Camp Shanks]] staging area at [[Orangeburg, New York|Orangeburg]], New York on 3 October 1943, where it received port call orders. On 8 October the division officially sailed from the [[New York Port of Embarkation]], and started arriving in [[Belfast]], [[Northern Ireland]] on 17 October. It then moved to England, where it trained and staged for forward movement to France.<ref name="stanton2006">{{cite book | title=World War II Order of Battle: An Encyclopedic Reference to U.S. Army Ground Forces from Battalion through Division, 1939–1946 | publisher=Stackpole Books | author=Stanton, Shelby | year=2006 | page=77 | isbn=0-8117-0157-3}}</ref>
