12th Group Army

The 12th (Group) Army is one of the three group armies of the Chinese People's Liberation Army's Nanjing Military Region.

Origin
The origin of the 12th Army lies in the surrender of the 74th Division of the Chinese Nationalist National Revolutionary Army, as well as with the sixth column of the Second Field Army.

Civil War
During the Chinese Civil War (a war between the communist "Red" army and the Chinese national army), the 12th Army was involved in a number of pivotal events in the Shanxi-Hebei-Shandong-Henan border region. On 8 December 1948, the 12th Army, 110,000 men strong, which had been surrounded by communist forces near Pengpu, on the Hwai river line, fell back into strong defensive positions, was aided by air drops, defied the communist commander's orders to surrender and managed to break free.

On 9 February 1949, the 34th, 35th and the 36th Divisions were incorporated into the Twelfth Army. On 29 November 1949, Chongqing was captured and later the Battle of Chengdu was fought.

Korean War
In December 1950, the 12th Army entered the Korean War. The People's Republic of China's (PRC) 31st Division of the 11th Army was incorporated into the 12th Army. The 11th Army returned to China in 1954.

Late-20th century
In 1985, the 12th Army was re-formed as a Group Army (field battalion). It was incorporated into the "60 June 179" division. The re-organization also involved the 2nd tank division and an artillery brigade.

In May 1989, the 12th Army's 34th, 36th and 110th Divisions, Artillery Brigade, and Anti-Aircraft Battalion were deployed to Beijing to enforce martial law and suppress the Tiananmen Square protests of 1989.

In 1998, the first 34th division of the 12th Army was re-deployed as a motorised infantry brigade (divorced from the 2nd tank division). The 35th division was moved to the Jiangsu military region. At a later stage, the 36th and the 179th divisions were motorised.
