Wolff also battled fiercely for civil rights and against the Vietnam War. He even offered the services of the aging veterans of the Lincoln Brigade to the North Vietnamese leader, Ho Chi Minh, who declined them. Later, Wolff campaigned against apartheid in South Africa, and raised money for ambulances in Sandinista-ruled Nicaragua in the 1980s, personally delivering twenty of them. Wolff completed two autobiographical novels, "A Member Of The Working Class" (published 2005) about his early life in New York, and "Another Hill" (published 1994) about his communist and Spanish experiences; he began a third book, "The Premature Anti-Fascist", describing his experiences after leaving Spain and during World War II, but did not finish it before his death.
