Interwar period

The 6th Division arrived at Camp Mills, New York, on 10 June 1919 after completing 6 months of training at Aignay-le-Duc, France, and occupation duty near and in Bad Bertrich, Germany. On arrival, emergency period personnel were discharged from the service at Camp Mills. The division proceeded to Camp Grant, Illinois, arrived 17 June, and remained there until September 1921. The division was inactivated, less the 12th Infantry Brigade and several smaller units, on 30 September 1921 at Camp Grant. Concurrently, the inactivated units were assigned active associate units for mobilization purposes. The 6th Division was allotted to the Sixth Corps Area for mobilization responsibility and assigned to the VI Corps. Camp Grant was designated as the mobilization and training station for the division upon reactivation. During the period 1921–39, the active elements of the 6th Division consisted of the 12th Infantry Brigade and other assorted divisional elements that formed the base force from which the remainder of the division would be reactivated in the event of war. The division headquarters was organized on 17 April 1926 with Organized Reserve personnel as a Regular Army Inactive (RAI) unit at Chicago, Illinois. Additionally, most of the division’s inactive elements were also organized n the Chicago area by mid-1927 as RAI units. The active elements of the division maintained habitual training relationships with divisional RAI units, as well as those of the VI Corps, XVI Corps, and the 85th, 86th, and 101st Divisions. The RAI and Reserve units often trained with the active elements of the division during summer training camps which were usually conducted at Camp Custer, Michigan, Fort Sheridan, Illinois, and at the regimental home stations of the 2nd and 6th Infantry Regiments. These two regiments also supported the Reserve units’ conduct of the Citizens Military Training Camps held at Fort Sheridan and Jefferson Barracks, Missouri. The 12th Infantry Brigade, reinforced by the active elements of the 6th Tank Company, 6th Field Artillery Brigade, 3rd and 14th Field Artillery Regiments, and the 6th Quartermaster Regiment, held maneuvers at Camp Custer in those years when funds were available. During these maneuvers, the 6th Division headquarters was often formed in a provisional status to train Regular and Reserve officers in division-level command and control procedures. The division was also provisionally formed for the August 1936 Second Army maneuvers at Camp Custer and Allegan, Michigan. For that maneuver, the division (12th Infantry Brigade as the nucleus) was reinforced by the Illinois National Guard's 8th Infantry (Colored), in addition to the other active divisional elements. Under the new “triangular” tables of organization, the 6th Division was reactivated 10 October 1939 at Fort Lewis, Washington. It was transferred to Fort Jackson, South Carolina, on 9 November 1939, relieved from the VI Corps, and attached to the IV Corps. After maneuvers in Louisiana in May 1940, the division was transferred to Fort Snelling, Minnesota, and assigned to the Second Army. The division participated in the Second Army maneuvers at Camp Ripley, Minnesota, in August 1940, in the Second Army maneuvers in Arkansas in August 1941, and in the GHQ maneuvers in Louisiana in September–October 1941. After the GHQ maneuvers the 6th Division was moved to Fort Leonard Wood, Missouri, for permanent station and arrived there 10 October 1941. [3]

Order of battle

World War II combat chronicle

The division moved to Hawaii in July and August 1943 to assume defensive positions on Oahu, training meanwhile in jungle warfare. It moved to Milne Bay, New Guinea, 31 January 1944, and trained until early June 1944. The division first saw combat in the Toem-Wakde area of Dutch New Guinea, engaging in active patrolling 14–18 June, after taking up positions 6–14 June. Moving west of Toem, it fought the bloody Battle of Lone Tree Hill, 21–30 June, and secured the Maffin Bay area by 12 July.

After a brief rest, the division made an assault landing at Sansapor, 30 July, on the Vogelkop Peninsula. The 6th secured the coast from Cape Waimak to the Mega River and garrisoned the area until December 1944.

The division landed at Lingayen Gulf, Luzon, in the Philippines on D-day, 9 January 1945, and pursued the Japanese into the Cabanatuan hills, 17–21 January, capturing Muñoz on 7 February. On 27 January, Special Operations units also attached to the Sixth United States Army took part in the Raid at Cabanatuan. The division then drove northeast to Dingalan Bay and Baler Bay, 13 February, isolating enemy forces in southern Luzon. The U.S. 1st Infantry Regiment operated on Bataan together with the Philippine Commonwealth forces, 14–21 February, cutting the peninsula from Abucay to Bagac.

The division then took part in the Battle of Manila, shifting to the Shimbu Line northeast of Manila, on 24 February to take part in the longest continuous combat operation of the division in the Battle of Wawa Dam. The 6th Division faced a tough seesaw battle versus the Shimbu Group as the Japanese Shimbu Group created network of tunnels, artillery positions, and machine gun nests in the hill country of Antipolo, San Mateo, and Montalban in Rizal Province. The terrain is formed by sharp hills and deep valleys, where direct assaults could be made in a day, and the next day units would be forced to retreat. The 6th Division took Mount Mataba on 17 April, Mount Pacawagan on 29 April,Bolog on 29 June, Lane's Ridge of Mount Santo Domingo on 10 July, and Kiangan, 12 July. The 6th remained with the Philippine Military forces in the Cagayan Valley and the Cordillera Mountains until VJ-day. [4]

After the war, the division moved to Korea and controlled the southern half of the United States zone of occupation until inactivated. [5]

Post World War

Cold War era

The 6th Division was reactivated 4 October 1950 at Fort Ord, California. There the division remained throughout the Korean War, training troops and providing personnel for combat, but was never deployed overseas as an entity itself and was again inactivated on 3 April 1956.

In the American build-up during the Vietnam War the Division was reactivated in 1967 at Fort Campbell, Kentucky, and later a forward brigade was located in Hawaii. [7] There was sentiment against sending the Division to Vietnam because its shoulder sleeve insignia (a red six-pointed star) invited a derisive nickname ("Commie Jew Division") that General Westmoreland, cognizant of troop morale problems, considered too offensive, and the decision was made instead to form the Americal Division (23rd Infantry Division), with less offensive insignia, in Vietnam itself. During June 1968 the US Joint Chiefs of Staff also declared the Division unsuitable for combatant deployment because it failed its readiness report and shortly thereafter the Division was inactivated on 25 July 1968. [8]

The Division never received its full TO&E equipment and most of its personnel were Vietnam returnees. The purpose for activating the division was to obtain military hardware which would eventually be turned over to the South Vietnamese.

The last incarnation of the Division came on 16 April 1986 under the command of Major General Johnnie H. Corns at Fort Richardson, Alaska when the assets of the 172nd Infantry Brigade were used to reactivate the 6th Infantry Division (Light). Over the next seven years the 6th was the U.S. Army's primary Arctic warfare division.

Organization 1989

The planned activation of two additional light infantry battalions for the division, one at Fort Richardson in October 1988, and one at Fort Wainwright in May 1989, was cancelled with the Fiscal Year 1988 budget. [9] To round-out the division the 6th Battalion, 297th Infantry, of the Alaska Army National Guard was activated on 1 September 1989. [10]

At the end of the Cold War parts of the division were organized as follows:

In 1988 the airborne companies (Charlie Airborne) of 1-17 Infantry, 2-17 Infantry and 4-9 Infantry were consolidated in 2-17 Infantry, giving the 6th ID an airborne battalion. Notable operational deployments included an eight-month deployment to the Sinai Peninsula in Egypt by 1st Battalion, 17th Infantry Regiment, in 1990 as part of the Multinational Force and Observers. The deployment began as a six-month rotation but was extended in August 1990 due to the Iraqi invasion of Kuwait which precipitated Operation Desert Shield and delayed the arrival of their relieving unit. The division headquarters was moved from Fort Richardson to Fort Wainwright (near Fairbanks) in 1990. [31] Commanders during the Arctic activation included Maj. Gen. Johnnie H. Corns (1986–1988), Maj. Gen. Samuel E. Ebbesen (1990–1992) [32] and Maj. Gen. David A. Bramlett (1992–1994). [33] The division had two active maneuver brigades and the Army Reserve's 205th Infantry Brigade (Light) was assigned as the division's roundout force. The 1st Battalion, 188th Air Defense Artillery of the North Dakota Army National Guard served as the division's roundout Air Defense Artillery. They were the only National Guard Air Defense battalion to ever roundout an active duty division. [34]

Inactivation

The division was inactivated most recently on 6 July 1994, and reduced to a single brigade, the 1st Brigade, 6th Infantry Division. In reality, the 6th no longer existed as a division and command of the brigade fell under the 10th Mountain Division (Light Infantry) at Fort Drum, NY. In April 1998, 1st Brigade was reflagged back to the separate 172nd Infantry Brigade from which the division had been reestablished in 1986. The 172nd Brigade was then reflagged as the 1st Brigade Combat Team (Stryker), 25th Infantry Division on 16 December 2006. [35]

On 16 October 2008 the division's HHC 6th Engineer Battalion [36] was reactivated as a non-divisional unit in Alaska. [37] In this new role it is configured as an Airborne unit with two subordinate engineer companies: the 23d Engineer Company [38] and the 84th Engineer Company. [39]
