USA HISTORY

Detailed explanation-1: -The losses at Chosin Reservoir had been painfully high for U.S. troops. The estimated 18, 000 casualties included about 2, 500 killed in action, 5, 000 wounded and almost 8, 000 who suffered from frostbite. But there were troops worse off still-the Chinese.

Detailed explanation-2: -China’s Chairman Mao Zedong had directed that the veteran 9th Army attack the US forces near Chosin. Stealthily, the Chinese army – roughly 120, 000 soldiers from the 20th and 27th Corps – took up positions near the Marines and US Army troops.
