In Operation Chromite, 40,000 United Nations infantry commanded by US General Douglas MacArthur made a surprise amphibious assault on Inchon, South Korea. The offensive had been preceded by five days of air and sea bombardment, but encountered only 6,500 North Korean infantry with minimal support. Inchon fell on 16 September, with the area secured by 19 September.

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.

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.
