[Includes 13 charts, and 46 illustrations] This book forms part of the “Vietnam Studies” series produced by various senior commanders who had served in the U.S. Army during the Vietnam War; each officer was chosen for their knowledge of the number of specialized subjects that were covered by the series. The challenge facing the General McChristian in 1965 was exceptionally daunting, as deputy head of General Westmoreland’s Intelligence section his orders were clear he was told that he must "Find the enemy!". A daunting task in a country filled with insurgents, uniformed enemy using other countries to move toward their targets, double agents, spies and a South Vietnamese Intelligence service to be integrated into his plans. As he himself put it: “I knew that finding the enemy was only part of the challenge. Our soldiers would have to fix and fight him. They would need to know enemy strength, capabilities, and vulnerabilities as well as information on the weather and terrain. Such intelligence had to be timely, accurate, adequate, and usable. It was to be my job to build an organization to meet that challenge.” It is remarkable that he achieved a good measure of success in his task in only two years in a country with so many endemic issues, and even more so that he was able to distil his story and of his department in to this detailed but very readable exposition of the Intelligence services in Vietnam. A complex and engaging study of a very difficult job done well.

This book examines intelligence's role in shaping America's perception of the Vietnam war and looks closely at the intelligence leadership and decision process in Vietnam.

Combat Operations: Taking the Offensive chronicles the onset of offensive operations by the U.S. Army after eighteen months of building up a credible force on the ground in South Vietnam and taking the first steps toward bringing the war to the enemy. The compelling story by George L. MacGarrigle begins in October 1966, when General William C. Westmoreland believed that he had the arms and men to take the initiative from the enemy and that significant progress would be made on all fronts over the next twelve months. Aware of American intentions, North Vietnam undertook a prolonged war of attrition and stepped up the infiltration of its own troops into the South. While the insurgency in the South remained the cornerstone of Communist strategy, it was increasingly overshadowed by main-force military operations. These circumstances, according to MacGarrigle, set the stage for intensified combat. The North Vietnamese and Viet Cong units retained the advantage, fighting only when it suited their purposes and retreating with impunity into inviolate sanctuaries in Laos and Cambodia. With Westmoreland feeling hamstrung by political constraints on his ability to wage war in the vast hostile areas along the border, 1967 ended with a growing uncertainty in the struggle to secure the countryside. Relying on official American and enemy primary sources, MacGarrigle has crafted a well-balanced account of this year of intense combat. His volume is a tribute to those who sacrificed so much in a long and irresolute conflict, and Soldiers engaged in military operations that place great demands on their initiative, skill, and devotion will find its thought-provoking lessons worthy of reflection.
