Chosin Reservoir

Chosin Reservoir was a northeastern Korean location whose significance in the book rests on the 1st U.S. Marine Division’s winter retreat from its vicinity to the port of Hungnam. The withdrawal, carried out amid a major Chinese offensive and extreme cold, became one of the defining ordeals of the retreat from Korea in late 1950.

Setting and Strategic Context

The reservoir lay in the northeast, where the U.S. Tenth Corps faced an exceptionally difficult retreat. In November 1950, Chinese forces struck the United Nations forces’ divided positions as winter conditions intensified. The Eighth Army was falling back from the Chongchon River toward Pyongyang, while the crisis in the northeast centered on the U.S. Tenth Corps and the route from Chosin Reservoir to Hungnam.

The Retreat to Hungnam

The book describes the withdrawal of the 1st U.S. Marine Division from Chosin Reservoir to Hungnam, a distance of forty miles, followed by evacuation from the port. The retreat took place in howling winds and snow, with temperatures reaching 25 degrees below zero. The division’s withdrawal became a measure of the scale of the emergency confronting United Nations forces in the northeast.

Narrative Significance

Chosin Reservoir is presented not as an isolated landmark but as the starting point of a retreat under severe military and environmental pressure. Its association with the forty-mile withdrawal to Hungnam gives the place a central role in the account of the Chinese offensive and the United Nations forces’ wider strategic retreat. The book compares the ordeal to Xenophon’s retreat of the Ten Thousand and Napoleon’s withdrawal from Moscow, placing the episode within a tradition of celebrated, hard-fought retreats.
