Korean War: Battle of Chipyong-ni, which represented the "high-water mark" of the Chinese incursion into South Korea, commences.

The Korean War was an armed conflict on the Korean Peninsula fought between North Korea and South Korea and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations Command (UNC) led by the United States. The conflict was one of the first major proxy wars of the Cold War. Fighting ended in 1953 with an armistice but no peace treaty, leading to the ongoing Korean conflict.

The Battle of Chipyong-ni, also known as the Battle of Dipingli, was a decisive battle of the Korean War that took place from 13 to 14 February 1951 between US and French units of the US 23rd Infantry Regiment and various units of the Chinese People's Volunteer Army (PVA) around the village of Chipyong-ni. The result was a United Nations Command victory. The battle, along with the Third Battle of Wonju, has been called "the Gettysburg of the Korean War".
