Operation Thao La
Open-knowledge reference entry
Operation Thao La (21 November–16 December 1971) was a Royal Lao Government (RLG) dry season offensive during the Laotian Civil War, aimed at severing the Ho Chi Minh Trail and retrieving the Lao Bolaven Plateau from the grip of the People's Army of Vietnam. Its objectives were the use of recently captured Salavan as a jumpoff point for occupying Tha Theng and Ban Phong. Key to the plan was a prearranged daily allotment of supportive tactical air power.
In the event, the Royalists captured their two objectives. However, they lost both Salavan and Paksong to the North Vietnamese; they also failed to find the Communist transshipment point whose conquest would have interdicted the Trail.
Overview
The Ho Chi Minh Trail was central to the People's Army of Vietnam (PAVN) strategy for the conquest of South Vietnam during the Second Indochina War. When a series of nine CIA-sponsored incursions from Military Region 3 (MR 3) and Military Region 4 (MR 4) of the southern panhandle of the Kingdom of Laos during 1969 and 1970 failed to interdict the Trail, the massive Operation Lam Son 719 was staged on 8 February 1971 to cut it. In the wake of this failure, CIA backed Laotian guerrillas and Royal Lao Government military irregulars made further attempts at severing the logistical lines of communication.
A string of Communist transshipment points, called Binh Trams, stretched the length of the Trail. Each garrisoned by approximately a PAVN regiment, and was responsible for construction and maintenance of an assigned Trail segment.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Operation Thao La”, the useful work is to connect “open-knowledge reference entry” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q23139065. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1971, 1969 and 1970.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
