In 1968, at the age of twenty-three, Karl Marlantes was dropped into the highland jungle of Vietnam, an inexperienced lieutenant in command of a platoon of forty Marines who would live or die by his decisions. Marlantes was a bright young man who was well trained for the task at hand but, as he was to discover, far from mentally prepared for what he was about to experience. In his thirteen-month tour he saw intense combat. He killed the enemy and he watched friends die. Marlantes survived, but like many of his brothers in arms, he has spent the last forty years dealing with his experiences.
