When Frank Johnson arrived in Vietnam in 1969, he was nineteen, a young soldier untested in combat like thousands of others--but with two important differences: Johnson volunteered for the elite L Company Rangers of the 101st Airborne Division, a long range reconnaissance patrol (LRRP) unit, and he kept a secret diary, a practice forbidden by the military to protect the security of LRRP operations. Now, more than three decades later, those hastily written pages offer a rare look at the daily operations of one of the most courageous units that waged war in Vietnam. Johnson served in I Corps, in northern Vietnam, where combat was furious and the events he recounts emerge, stark and compelling: walking point in the A Shau Valley, braving enemy fire to rescue a downed comrade, surviving days and nights of relentless tension that suddenly exploded in the blinding fury of an NVA attack.
