has completed his fifth and final book on the Vietnam War, an oral history, titled "Voices of the Vietnam War." Nau was drafted out of Penn State in the later rounds of 1966 and returned to school in 1968 after serving as an artillery soldier in the war. One of his books, "They Heard the Bugle's Call," triggered a $40,000 fundraising campaign that financed a Vietnam War memorial in Pawtucket, Rhode Island, where Nau worked for 30 years as sports editor of the local newspaper.
