The Battle of Unsan, also known as the Battle of Yunshan, was a series of engagements of the Korean War that took place from 25 October to 4 November 1950 near Unsan, North Pyongan province in present-day North Korea. As part of the People's Republic of China's First Phase Campaign, the People's Volunteer Army (PVA) repeatedly attacked the Republic of Korea Army's (ROK) 1st Infantry Division near Unsan beginning on 25 October, to surprise the advancing United Nations Command (UNC). The United States' (US) 8th Cavalry Regiment was encircled on 1–2 November and broke out with the loss of most of its heavy equipment.
The Battle of Onjong, also known as the Battle of Wenjing, was one of the first engagements between Chinese and South Korean forces during the Korean War. It took place around Onjong in present-day North Korea from 25 to 29 October 1950. As the main focus of the Chinese First Phase Offensive, the People's Volunteer Army (PVA) 40th Corps conducted a series of ambushes against the Republic of Korea Army (ROK) II Corps, effectively destroying the right flank of the United States Eighth Army while stopping the UN advance north toward the Yalu River.
The Battle of the Ch'ongch'on River, also known as the Battle of the Ch'ongch'on, was a decisive battle in the Korean War that took place from November 25 to December 2, 1950, along the Ch'ongch'on River Valley in the northwestern part of North Korea. In response to the successful Chinese First Phase Campaign against the United Nations (UN) forces, General Douglas MacArthur launched the Home-by-Christmas Offensive to expel the Chinese forces from Korea and to end the war. Anticipating this reaction, the Chinese People's Volunteer Army (PVA) Commander Peng Dehuai planned a counteroffensive, dubbed the "Second Phase Campaign", against the advancing UN forces.
During the 1989 Tiananmen Square protests and massacre in Beijing, the Chinese People's Liberation Army (PLA) played a decisive role in enforcing martial law, using force to suppress the demonstrations in the city. The killings of protestors in Beijing continue to taint the legacies of the party elders, led by Chinese leader Deng Xiaoping, and weigh on the generation of leaders whose careers advanced as their more moderate colleagues were purged or sidelined at the time. Within China, the role of the military in 1989 remains a subject of private discussion within the ranks of the party leadership and PLA.
The 1989 Tiananmen Square protests and massacre saw a massive redeployment of People's Liberation Army (PLA) troops into and around Beijing. After the declaration of martial law, the Central Military Commission (CMC) mobilized at least 22 divisions from 13 Armies, which converged on Beijing. This force far exceeded the local garrison, with troops being sent in from across China. Altogether, roughly 300,000 troops were involved in the campaign to quell the protests. By their end, the PLA had proven that it was largely willing to enforce party decrees with lethal force. Multiple significant breaches of military discipline occurred after the imposition of martial law. Some cases involved officers or entire units being unwilling to obey directives from farther up the chain of command, others related to the misuse of military equipment, and some were responsible for casualties incurred during the night of June 3. It is unclear when, how, or even if some PLA units received orders to open fire on the protesters, and so knowing whether or not an incident amounts to insubordination is difficult. If the PLA as a whole received orders to use lethal force, CMC chairman Deng Xiaoping must have given his assent to it. CMC vice-chairman and President Yang Shangkun's orders to the Central Military Commission on the 20th of May 1989 explicitly deny troops the authority to use lethal force during martial law, even when their lives are threatened by the protesters. According to Li Xinming's report to the politburo on June 19 however, 10 PLA soldiers did end up dying, along with 13 from the People's Armed Police. For these 23 dead, they inflicted 218 deaths on the protesters, although some sources place this number in the thousands.
