He then plunges right into the action: the massing of Chinese forces in about ten-to-one strength; the Marines' command problems due to the climate and terrain and high-level over confidence; and the onset of the overwhelming Chinese assault.With a wealth of tactical detail and small-unit action Chosin: Heroic Ordeal of the Korean War is the most complete book written to date on this iconic battle. Author Eric Hammel's masterful account offers invaluable perspective on war at the gut level.
