Vietnam Finds Mass Grave of Communist Soldiers A mass grave has been found containing the remains of 23 communist soldiers believed to have been killed during the Tet Offensive, seen by many as the turning point of the Vietnam War. Col. Nguyen Minh Hung of provincial military command in central Khanh Hoa province said Tuesday that construction workers who were expanding a highway found the site last week. He says it took 30 soldiers and militiamen six days to recover the remains, none of which were identified. The soldiers were believed to have been killed while withdrawing after attacking an airport and the local military headquarters of the Saigon government, he said. Thousands of Viet Cong guerrillas attacked major towns across southern Vietnam during the Tet Offensive in January 1968.
