The 4th Infantry Division (“Ivy Division”) was organized in December 1917 at Camp Green, North Carolina, and sent overseas to France 5 June 1918, fighting in the Aisne - Marne, St. Mihiel and Meuse - Argonne during World War I, cracking the Hindenburg Line and stopping the Kaiser’s all-out drive to Paris. After seven months on occupation duty in Germany the division returned to the U.S. and was inactivated 1 August 1919. In June 1940 it was reraised at Fort Benning and sent to England 18 January 1944 for training for the invasion of France. The 4th Infantry Division landed at Utah Beach on D-Day, 6 June 1944, relieved the 82d Airborne Division isolated in the St. Mere Eglise marshes and spearheaded the drive to Cherbourg. After clearing the Cotentin Peninsula it turned south to break through the German Army’s flank in France and was the first U.S. division to liberate Paris. The division continued its drive through Belgium and fought in the Hurtgen Forest until it met the German counteroffensive in the Ardennes head on. After severe combat the division went over to the offensive and crossed the Rhine at Worms, becoming the first Allied division to set foot on German soil in World War II. Inactivated at Camp Butner, North Carolina, it was reraised as a training division in July 1947 at Fort Ord, California, converted into a combat division, and sent to Germany in 1951. In September 1956 the division returned to the U.S. at Fort Lewis, Washington, where it was serving when alerted for Vietnam. The bulk of the 4th Infantry Division went to the II Corps Tactical Zone, but a brigade reinforced with the divisional armor battalion was sent into the III Corps Tactical Zone. In August 1967 the elements of the 3rd Brigade, including the armor, were officially turned over to the 25th Infantry Division in exchange for the elements of its own 3rd Brigade, which was in the II Corps area. This constituted the only major element switch between divisions during the Vietnam war-transferral of the 3rd Brigade Headquarters of the 4th Infantry Division to the operational control of Task Force OREGON and relocation into the I Corps Tactical Zone at Duc Pho. The 4th Infantry Division entered combat as soon as it arrived in Vietnam, sending a brigade into War Zone C of Tay Ninh Province as part of Operation ATTLEBORO (14 September - 24 November 1966). When the bulk of the division arrived it immediately conducted a major operation near the Cambodian border in Pleiku Province, which lasted through December 1966. In 1967 the division continued border surveillance operations in Pleiku and Kontum Provinces, while its 3rd Brigade was participating in Operation JUNCTION CITY (February - May 1967), again in War Zone C . Throughout 1968 and into 1969 the division continued operations in the western Highlands, seeing fierce action in the border regions. In June 1970 the 4th Infantry Division thrust into Cambodia to punish the North Vietnamese Army sanctuaries there. The 3rd Brigade of the division pulled out of Vietnam first in INCREMENT III of the U.S. Army withdrawal and was inactivated at Fort Lewis. When the division was sent back to the U.S. in INCREMENT V to Fort Carson, Colorado, its former 3rd Brigade joined it from the 25th Infantry Division, which had returned to Hawaii. The 4th Infantry Division served 1,534 days in Vietnam.
