Where was the Battle of Chosin Reservoir Fought?

The Battle of Chosin Reservoir was fought from November 27 to December 13, 1950, and took place in the mountainous and freezing terrain of North Korea, where 30,000 United Nations Command troops battled 120,000 Chinese Communist Forces in the frozen, mountainous terrain surrounding the Chosin Reservoir in northeastern North Korea.

During the Battle of Chosin Reservoir, which began on November 27, 1950, the Chinese People’s Volunteer Army launched a heavy surprise attack as they encircled United Nations troops near the Chosin Reservoir.


Despite being outnumbered and facing extreme weather conditions, the Allied forces executed a withdrawal over the dangerous North Korean terrain, as they inflicted between 40,000 and 50,000 casualties on the Chinese but lost 18,000 due to combat and the freezing weather, while evacuating a majority of their own casualties and equipment.


The Battle of Chosin Reservoir serves as a primary battle in the Korean War because it marked a turning point where Chinese intervention forced UN forces to retreat out of North Korea, ending current hopes for the reunification of the Korean Peninsula.


Yet, the major resilience and discipline shown by United States Marines are cited as examples of military tenacity under dreadful circumstances.


Furthermore, the battle highlighted the global stakes of the Korean War, as China and the United States became involved.
