Operation Bedrock (Laos) (1–9 November 1971) was a military offensive staged by the Royal Lao Armed Forces against the People's Army of Vietnam in Military Region 4 of the Kingdom of Laos. Its purpose was disruption of the supply of rice to Communist forces occupying the Ho Chi Minh Trail. It was successful.

Overview

From the start of the Vietnam War, the Ho Chi Minh Trail became crucial to the People's Army of Vietnam strategy as its key to conquering South Vietnam. Over the war years, the Trail expanded to 4,000 miles of road, trail, and waterway. Tchepone in the panhandle of the Kingdom of Laos became a key transshipment and logistics center for the communists. Its significance can be measured by the fact that after many attempts to cut the Trail from Laos, the multi-divisional Operation Lam Son 719 was launched on 8 February 1971 from South Vietnam to capture Tchepone.

From 28 July through 31 October 1971, Royalist forces of the Kingdom of Laos had staged Operation Sayasila in Military Region 4 (MR 4). They managed to wrest control of Route 23 and the towns of Salavan and Paksong and their associated airstrips from the People's Army of Vietnam (PAVN).
