To Vietnam in Vain: Memoir of an Irish-American Intelligence Advisor, 1969-1970 (Paperback) (ISBN-13: 9780786499670)

American military advisors in South Vietnam came to know their allies personally--as few American soldiers could. In addition to fighting the Viet Cong, advisors engaged in community building projects and local government initiatives. They dealt firsthand with corrupt American and South Vietnamese bureaucracies. Not many advisors would have been surprised to learn that 105mm artillery shells were being sold on the black market to the Viet Cong. Not many were surprised by the North Vietnamese victory in 1975.

This memoir of a U.S. Army intelligence officer focuses on the province advisors who worked with local militias that were often disparaged by American units. The author describes his year (1969-1970) as a U.S. advisor to the South Vietnamese Regional and Popular Forces in the Mekong Delta.
