The unit first activated on 10 June 1944 in the United States, under the command of Lieutenant GeneralRobert L. Eichelberger. The Eighth Army took part in many of theamphibious landings in theSouthwest Pacific Theater ofWorld War II, eventually participating in no less than sixty of them. The first mission of the Eighth Army, in September 1944, was to take over from theU.S. Sixth Army inNew Guinea,New Britain, theAdmiralty Islands and onMorotai, in order to free up the Sixth Army to engage in thePhilippines Campaign (1944–45).
The Eighth Army again followed in the wake of the Sixth Army in December 1944, when it took over control of operations onLeyte Island on 26 December. In January, the Eighth Army entered combat onLuzon, landing theXI Corps on 29 January nearSan Antonio and the11th Airborne Division on the other side ofManila Bay two days later. Combining withI Corps andXIV Corps of Sixth Army, the forces of Eighth Army next envelopedManila in a great double-pincer movement. Eighth Army's final operation of thePacific War was that of clearing out the southern Philippines of theJapanese Army, including on the major island ofMindanao, an effort that occupied the soldiers of the Eighth Army for the rest of the war.
Eighth Army was to have participated inOperation Downfall, the invasion of Japan.[6] It would have taken part inOperation Coronet, the second phase of the invasion, which would have seen the invasion of theKantō Plain on easternHonshū.[7] However, the Japanese surrender cancelled the invasion, and the Eighth Army found itself in charge of a peacefuloccupation.[8]Occupation forces landed on 30 August 1945, with its headquarters inYokohama, then the HQ moved to theDai-Ichi building inTokyo.[9]
At the beginning of 1946, Eighth Army assumed responsibility for occupying all of Japan.[9] Between February 1946 and October 1949, the Eighth Army tried 996 suspectedJapanese war criminals in theYokohama War Crimes Trials, convicting 854. These trials constituted the majority of American war crimes trials in the Asia-Pacific region.[10] Four quiet years then followed, during which the Eighth Army gradually transitioned from a combat-ready fighting force into a constabulary.[11] Lieutenant GeneralWalton H. Walker took command in September 1948, and he tried to re-invigorate the Army's training, with mixed success.[12]

In June 1950 75,000North KoreanKorean People's Army (KPA) troops withSoviet made tanks invaded South Korea, igniting theKorean War.[13][14] U.S. naval and air forces quickly became involved in combat operations, and it was soon clear that U.S. ground forces would have to be committed. To stem the North Korean advance, the occupation forces in Japan were thus shipped off to South Korea as quickly as possible, but their lack of training and equipment was telling, as some of theinitial U.S. units were destroyed by the KPA. However, the stage was eventually reached as enough units of Eighth Army arrived in Korea to make a firm front. The KPA threw themselves against that front, thePusan Perimeter, and failed to break it.
Eighth Army arrived in July 1950 and never left. —Lt. Gen. Thomas S. Vandal, CG, Eighth Army, 29 August 2017[15]
In the meantime, Eighth Army had reorganized, since it had too many divisions under its command for it to exercise effective control directly. TheI Corps and theIX Corps were reactivated in the United States and then shipped to Korea to assume command of Eighth Army's subordinate divisions.
The stalemate was broken by theInchon landings of theX Corps (consisting of soldiers and Marines). The KPA, confronted with this threat to their rear areas, combined with a breakout operation at Pusan, broke away and hastily retired north.
Both South and North Korea were almost entirely occupied by United Nations forces. However, once U.S. units neared theYalu River and the frontier between North Korea andChina, the ChinesePeople's Volunteer Army (PVA) intervened and drastically changed the character of the war. Eighth Army was decisively defeated at theBattle of the Chongchon River and forced to retreat back into South Korea, the longest retreat of any U.S. military unit in history. General Walker was killed in a jeep accident on 23 December 1950, and replaced by Lieutenant generalMatthew Ridgway. The overstretched Eighth Army suffered heavily with the Chinese offensive, who were able to benefit from shorter lines of communication and with rather casually deployed enemy forces. The Chinese broke through the U.S. defenses despite U.S.air supremacy and the Eighth Army and U.N. forces retreated hastily to avoid encirclement. The Chinese offensive continued pressing U.S. forces, which lostSeoul, the South Korean capital. Eighth Army's morale andesprit de corps hit rock bottom, to where it was widely regarded as a broken, defeated rabble.
Ridgway forcefully restored Eighth Army to combat effectiveness over several months. Eighth Army slowed and ultimately halted the Chinese advance at the battles ofChipyong-ni andWonju. It then counter-attacked the Chinese, re-took Seoul, and drove to the38th parallel, where the front stabilized.
When Ridgway replacedGeneral of the ArmyDouglas MacArthur as the overall U.N. commander, Lieutenant generalJames Van Fleet assumed command of Eighth Army. After the war of movement during the first stages, the fighting in Korea settled down to a war of attrition. Ceasefire negotiations were begun at the village ofPanmunjom in the summer of 1951, and they dragged on for two years. During the final combat operation of the war, Lieutenant generalMaxwell D. Taylor (promoted to general 23 June 1953) commanded the Eighth Army. When theMilitary Demarcation Line was finally agreed to by theKorean Armistice Agreement, South Korea and North Korea continued on as separate states.

During theaftermath of the Korean War, the Eighth Army remained in South Korea. By the 1960s, I Corps, consisting of the7th Infantry Division and the2nd Infantry Division, remained as part of the Eighth Army. Then, in 1971, the 7th Infantry Division was withdrawn, along with the command units of I Corps, which were moved across the Pacific Ocean toFort Lewis,Washington.[16] Later, in March 1977, a memo from President Jimmy Carter said "...American forces will be withdrawn. Air cover will be continued." Bureaucratic resistance from the Executive Branch, with support in Congress, eventually saw the proposal watered down. Eventually one combat battalion and about 2,600 non-combat troops were withdrawn.[17]
This left the 2nd Infantry Division at theKorean Demilitarized Zone to assist theSouth Korean Army. Besides forming a trip-wire against another North Korean invasion, the 2nd Infantry Division remained there as the only Army unit in South Korea armed withtactical nuclear weapons. (Otherwise, there is only theU.S. Air Force in South Korea and onOkinawa.) All nuclear weapons were taken from the Army to be under Air Force control. Later, in 1991,[18] all U.S. nuclear weapons were removed from South Korea.
At the end of theCold War Eighth Army consisted of the following units:
Eighth Army,Yongsan Garrison,South Korea[19].svg)
2nd Infantry Division,Camp Casey[19]
17th Aviation Brigade,Camp Coiner[19][20][21].svg)
1st Signal Brigade, Camp Humphreys[24]
8th Military Police Brigade (Provisional), Camp Coiner[19]
501st Military Intelligence Brigade (Provisional), Yongsan Garrison[31]
18th Medical Command, Seoul[19][21] (the following peacetime listing is incomplete)
19th Support Command,Daegu[19] (the following peacetime listing is incomplete)In 2003, plans were announced to move the 2nd Infantry Division southward. The division, with 15 bases north of the Han River and just south of the DMZ, was to be the most important formation to be moved south of the Han River in two phases "over the next few years" a joint statement between the South Korean and U.S. governments said on June 5, 2003.[42] As of 2015, it appears that one brigade of the 2nd Infantry Division will remain atCamp Casey, nearDongducheon.
The headquarters of the Eighth Army wasYongsan Garrison, but moved southward toCamp Humphreys by 2019.[3] In April 2017 the Eighth Army headquarters began its move from Yongsan to Camp Humphreys and held a ceremony to relocate a statue of General Walton Walker.[43]
Other army units based in South Korea:
The 8th Army Band is the official musical unit of the HQ 8th Army and supportsUnited States Forces Korea and theUnited Nations Command.[48] The 41-member band was founded in 1916 as the Band of the 35th Infantry Regiment. During World War II, the band, then known as the 25th Infantry Division Band based out ofHawaii, served in thePacific Theater, being a participant in Central Pacific and Guadalcanal campaigns. It was reorganized in November 1950 and reassigned to the newly formed ROK, the same year the Korean War began.[49] Awards and honors the band has received include theMeritorious Unit Commendation and twoRepublic of Korea Presidential Unit Citations.[50] NicknamedFreedom's Ambassadors due to itsarea of responsibility, it has performed at events such as theWonju Tattoo, theGangwon International Tattoo as well as Korean War memorial ceremonies in the country.[51][52] In June, 2015, members of the 8th Army Band celebrated its 99th anniversary inMongolia with a concert onSükhbaatar Square.[53]
TheKorean Service Corps was a reserve force composed of South Korean volunteers who were augmented to the 8th Army. They provided labourers who were used to carry ammunition and supplies, and support the overall logistic elements of the army. It is today, aparamilitary civilian formation that isbattalion-sized. Continuing is role as acombat service support unit, it is capable of being expanded and mobilized during a wartime situation.
