After halting the North Korean advance, the UN forces counterattacked. In just a few weeks, they cleared South Korea then launched their own invasion of the North. However, their success now threatened China, which secretly began moving in its own forces to protect North Korea.

Main Events

UN Offensive in Korea

On 15 September 1950, United Nations forces landed at Inchon, South Korea, completely outflanking the bulk of the North Korean troops, who were fighting 240 km to the southeast at the Pusan Perimeter. With the North Koreans in full retreat, the UN retook Seoul by 25 September, crossed the 38th parallel on 9 October, and captured the North Korean capital of Pyongyang on 19 October. On 26 October, South Korean forces reached Chosan on the Yalu River, the border with China.

Battle of Chamdo

After months of failed negotiations between the People's Republic of China and de facto independent but Chinese-claimed Tibet, 40,000 troops of the People's Liberation Army (PLA) crossed the Jinsha River into the Chamdo region of Tibet - which China at the time claimed as part of Xigang province. The PLA quickly defeated the 8,500-strong Tibetan Army and captured the town of Chamdo.

People's Volunteer Army

In response to the United Nations invasion of North Korea, the People's Republic of China (PRC) formed the People's Volunteer Army (PVA). Although this force was composed of troops from the People's Liberation Army, it was not officially tied to the PRC in order to avoid a general war between China and the United States. The PVA crossed the Yalu River into Korea on 19 October 1950.

End of the Republic of South Maluku

The Indonesian Army extinguishes the Republic of South Maluku, although guerrilla forces remain at large in the islands for years. In the aftermath, the Dutch government agrees to the resettlement of many Moluccan KNIL soldiers and their families - about 12,500 people in total - in the Netherlands, with the intention of one day repatriating them to Indonesia.
