64th Group Army

The 64th Group Army, former 64th Corps and 64th Army Corps, was a military formation of China's People's Liberation Army that existed from 1949 to 1998.

Chinese Civil War and Korean War
The 64th Corps was created in January 1949 under the Regulation of the Redesignations of All Organizations and Units of the Army, issued by the Central Military Commission on 1 November 1948, based on the 4th Column of the Jinchaji Military Region. Its lineage could be traced to the Jizhong Column, formed in 1945.

As of its formation, the Corps was composed by 3 divisions: the 190th, 191st and 192nd.

The Corps was part of the 19th Army Group. It took part in many battles, especially the Pingjin Campaign during the Chinese Civil War.

In October 1950, Artillery Regiment, 64th Corps activated. In February 1951 the regiment was renamed the 171st Artillery Regiment. In January 1951, the corps was re-equipped with Soviet-built small arms.

In February 1951, the Corps entered Korea with all its subordinated divisions as a part of the P eople's Volunteer Army. During its deployment in Korea, it took part in the Fifth Phase Offensive, during which the corps suffered heavy losses by indirect fire at the riverbank of Imjin River, but made significant territorial gains against the confronting U.S. 24th Infantry Division.

During the First Battle of Maryang San in November 1951, Hill 355, nicknamed Little Gibraltar, was a strategic feature, commanding the terrain for twenty miles around, so the Communists were determined to take it before the truce talks came to an agreement that would lock each side into their present positions.

Hill 355 was held by the 3rd U.S. Infantry Division, who linked up with the Canadian Royal 22nd Regiment on the Americans' western flank. On November 22, the 64th Army (around 40,000 men) began their attack: over the course of two days, the Americans were pushed back from Hill 355 by elements of the Chinese 190th and 191st Divisions. The 3rd U.S. Infantry Division tried to recapture the hill, but without any success, and the Chinese had moved to the nearby Hill 227, practically surrounding the Canadian forces. A raid led by experienced Canadian non-commissioned officer Léo Major was mounted to relieve the pressure.

Port Arthur
In August 1953 the corps pulled out of Korea and was stationed in Fengcheng, Liaoning, and later moved to Andong, Liaoning.

In February 1955, as Soviet 39th Army withdrawing from the Port Arthur area, PLA 63rd Corps, with all its three divisions and reinforced by 170th Artillery Regiment from 63rd Corps; Independent Tank Regiment of Huabei Military Region, and 1st Public Security Division, moved into Port Arthur to receive equipment left by the Soviet Army.

The division was then temporarily attached to the 64th Corps.

After the relieving, the 190th Infantry Division, now the 1st Mechanized Division (1st formation), detached from the corps. In March 1953, the 21st Railway Security Division joined the corps and was renamed as the 190th Infantry Division(2nd formation).
