Originally published in 1976. This narrative describes the evacuation of more than 1,400 American soldiers, Marines, and airmen, and Vietnamese men, women, and children from the Kham Duc Special Forces camp in southern I Corps on 12 May 1968. It treats the geographical and topographical setting, the threat to the camp posed by two regiments of the North Vietnamese Army, and the danger to the camp and its inhabitants from the communist seizure of all the high ground around the camp. The monograph devotes individual chapters to the US Army and Marine helicopter rescue efforts, tactical air support, and tactical airlift. The final chapter deals with the attempts to rescue the last three men at Kham Duc. American aircraft losses were severe during the evacuation, and the successful outcome of the mass rescue depended upon the skill and courage of American aircrews. Had command and control been better, losses probably would have been less severe.
