Show of the week: Uncommon Courage: Breakout at Chosin

The Battle of the Chosin Reservoir was a turning point of the Korean War, when badly outnumbered U.N. forces were encircled by Chinese communists who had secretly entered the conflict. Leading 500 U.S. Marines on a daring nighttime rescue mission was Lt. Chew-Een Lee, who overcame injuries and temperatures as low as minus-30 Fahrenheit to help 8,000 Marines escape capture. This brisk documentary also explains how Lee transcended racism to become the first Chinese-American officer in the history of the Marines. Monday, May 31, at 8 p.m., Smithsonian Channel
