The Battle of Khe Sanh
It was the longest and deadliest battle of the Vietnam War, with arguments still raging about what actually took place. A political chess game, American soldiers were caught in enemy territory with little or no strategy and casualties soared. US soldiers were the pawns of sacrifice in a situation beyond their control.
Skeletons of the dead enemy hung from barbed wire. No helicopter could survive for more than 25 seconds before coming under fire. In the US, the nation looked on in horror. No precedent existed for such a ferocious conflict.
