It was the Army that knew the worst frustration, from July 1951 to the end of the war. The mission of the Army is to meet the enemy in sustained ground combat, and capture or destroy him. The Army was indoctrinated that strength lay not in defense but in attack, and that the offensive, as Clausewitz wrote, always wins. The Army not only could not win; it could not even work at the task. Yet it was locked in a wrestler’s grip with the enemy, suffering hardship, taking losses, even after the peace talks began.
