Aftermath
While the Chinese were able to expel the UN forces from the
reservoir, U.S. forces inflicted heavy casualties on the Chinese as
they fought for their own survival. The Marines' breakout was
helped in part by Chinese American Marines who overheard the
People's Liberation Army battle plans in Chinese. [citation needed]
After their departure from North Korea, the Marines were returned
to the South, where they continued to fight as part of UN forces
until the armistice in July 1953.
To this day, the U.S. Marines consider the Battle of the Chosin
Reservoir to be one of the proudest parts of their own history
despite the heavy losses. Likewise, the Chinese People's Liberation
Army considers the Battle of the Chosin Reservoir an honor. This
campaign, with the simultaneous victory against U.S. forces to the
west, was the first time in a century a Chinese army was able to
defeat a Western army in a major battle, despite the heavy
losses.
