Following the North Korean assault on the Republic of Korea in June of 1950, the invaders captured more than a thousand American soldiers and brutally executed hundreds more. American prisoners who survived their initial moments of captivity faced months of neglect, starvation, and brutal treatment as their captors marched them north toward prison camps in the Yalu River Valley. Cold Days in Hell provides a detailed account of their captivity and offers valuable insights into an ongoing issue: the conduct of prisoners in the hands of enemy captors and the rules that should govern their treatment.
