South Korea, April, 1968: MPs carry the flag-draped caskets of Sgt. James L. Anderson of Camp Springs, Md., and Spc. 4 Larry M. Wood of Barstow, Ill., who along with two South Koreans were killed while on patrol at the DMZ. Two other Americans were wounded in the ambush. In spite of considerable evidence found at the scene, North Korean Maj. Gen. Chung Kook Pak insisted at a meeting that "we had nothing to do with the incident." Rear Adm. John V. Smith, senior negotiator for the UNC, demanded "a concrete assurance that this will not happen again," but four more Americans were killed in a similar attack at the DMZ in October, 1969.
