The Battle of Chipyong-ni, Feb. 13-15, 1951
‘There were about 15 battles in history that were decisive turning points.  Over the next year, I intend to do posts on all of them.  At any rate, Feb. 13 marks the start of the battle of Chipyong-ni, the turning point in the Korean War when UN forces finally stood firm against a Chinese advance that had been unstopped for over 1,000 miles.  One U.S. Regiment, dug in and surrounded on all sides, stood athwart the advance of 25,000 Chinese – and over three days, they won the battle.  It is one of the greatest defenses of the modern era.’
