The Major Henderson incident occurred on June 30, 1975. A dozen North Korean guards and reporters assaulted US Army Major W. D. Henderson, a United Nations Command (UNC) security officer in the Joint Security Area (JSA), injuring him seriously. Henderson was trampled on by the North Koreans and suffered a fractured larynx before he was rescued by United Nations Command guards. Henderson survived, continued his career, and later retired from the United States Army.
