Campaign 972 (28 October 1972 – 22 February 1973) was the final offensive in the south of the Kingdom of Laos by the People's Army of Vietnam (PAVN). After fending off a score of Royal Lao Government attacks against the Ho Chi Minh Trail between June 1969 and late 1972, the PAVN attacked and essentially cut Laos in two at Khong Sedone by November 1972. Sporadic ongoing fighting, especially for control of Paksong, continued until 8 February 1973. Although a ceasefire officially ended the Laotian Civil War at noon on 23 February with Salavan, Thakhek, and Lao Ngam in Communist hands, the PAVN launched another successful assault on Paksong 15 minutes later.
