The 5th Marine Division was a United States Marine Corps infantry division. Created during World War II, the 5th Division saw its first combat action during the Battle of Iwo Jima in 1945 where it sustained the highest number of casualties of the three Marine divisions of the V Amphibious Corps (invasion force). The 5th Division was to be part of the planned invasion of the Japan homeland before Japan surrendered. The 5th Division received the Presidential Unit Citation for extraordinary heroism on Iwo Jima in February 1945 (awarded to the V Amphibious Corps). The 5th Division was disbanded in 1946.

The 5th Division was reactivated in 1966 during the Vietnam War. The 5th Tank Battalion, RLT 26, RLT 27 and RLT 28 under the command of the 1st Marine Division (Reinforced) staged in the Philippines upon arrival from Camp Pendleton, California, departed Subic Bay aboard USS Washtenaw County landing in Da Nang in July 1967. 5th Tanks provided mission fire control support at every strategic Hill in South Vietnam. 5th Tanks received two Presidential Unit Citations (PUC) for extraordinary heroism in the battles at Khe San and Hue City. Ord & Maint Co. suffered horrendous losses on Hill 88 as 21 Marines perished from mortar fire to the 105mm ordanance bunker. The worst single day casualties suffered by the 5th Tank Battalion during the Vietnam War. Its 13th, 26th, and 27th regiments were under the command of the 3rd Marine Division (Reinforced) and 1st Marine Division (Reinforced) until 19 March 1970. The 26th Marine Regiment was awarded the Presidential Unit Citation for extraordinary heroism during the Battle of Khe Sanh in 1968. The 5th Division was formally deactivated at Camp Pendleton, California on 26 November 1969.


World War II[edit]

The 5th Marine Division was activated on Armistice Day, 11 November 1943. The division's Headquarters Battalion officially began operating at Marine Corps Base Camp Pendleton on 1 December, at which time men and equipment began streaming into Camp Pendleton. The official activation date for the Division was 21 January 1944. The division had a solid core of combat veterans from the beginning however there were many issues raising the total required number of Marines as the Marine Corps had to provide combat replacements to other divisions and staff the newly formed 6th Marine Division also.[1] Among the personnel forming the new division were Marines from the former 1st Marine Parachute Regiment, the Raider Training Battalion, the Parachute Training School, West Coast, and the Parachute Replacement Company.

Parts of the division began to deploy overseas to act as the reserve force during the Battle of Guam where they were not needed. Because of this they were sent to Camp Tarawa near Hilo, Hawaii for further training. After more extensive training the division loaded ships and left Hawaii in January 1945. By mid-February they were sailing past Saipan headed for Iwo Jima.

Iwo Jima[edit]

(Presidential Unit Citation: Assault Troops, Fifth Amphibious Corps, 19 to 28 February 1945)

The 5th Division landed on Iwo Jima on 19 February 1945. The division landed on the left northeast of Mount Suribachi and sustained heavy initial losses so much so that by that afternoon the 26th Marines had to be released as the division reserve.[2] The 5th Marine Division would fight on Iwo Jima from 19 February until 18 March where they would sustain 1,098 killed in action and 2,974 wounded in action. This was the highest casualty rate amongst the Marine divisions involved in the invasion. The 5th Marine Division began loading onto ships on 18 March and finally left Iwo Jima on 27 March 1945 sailing for Hawaii.[3]

On 21 March 1945 the 5th Marine Division Cemetery was formally dedicated on Iwo Jima. Chaplains prayed, Major General Keller E. Rockey added a tribute to the dead and Lieutenant Roland B. Gittelsohn, U.S. Navy and a 5th Division chaplain, spoke of friends buried and "the ghastly price of freedom...." The flag was raised then lowered to half-mast. Taps was played echoing across the dark foreboding ash of Sulfur Island.

Iwo Jima became an important support and emergency landing field for aircraft based out of the Marianas. In recognition of the 5th Marine Division's sacrifice in securing the island, the US Army Air Corps 9th Bombardment Group named a B-29 "The Spearhead", with elaborate nose art depicting the Division's insignia and the flag raising on Mt. Suribachi.

The 5th Marine Division returned to Camp Tarawa, Hawaii and remained there until the end of the war. After the Japanese surrender they set sail for Japan where they occupied the southern island of Kyūshū. The division left Japan in November 1945 and arrived in San Diego, California the week of Christmas 1945. The majority of the division's Marines were discharged shortly thereafter the division was deactivated on 5 February 1946.
