Operation Beaver Cage was a U.S. Marine Corps and U.S. Navy Joint Operation in South Vietnam along the coastline of the Ben Hai River in the Quảng Trị Province. The operation took place from 23 August through 5 September 1966.


The United States Army and the U.S. Navy conducted joint operations in search of tunnels leading in from and near the coast line of the Bon Hai river. The tunnels were believed to be created by the Vietcong 4th Division led by Pham Ngoc Thao. The tunnels were used in transport of supplies, and small attacks on forward American patrols. The cecondary objective of the operation was to infiltrate the tunnels, pushing the enemy out into ambush locations.

U.S. Army[edit]

Bravo Company 7th Cavalry Regiment led the operation, ambushing over ten locations and demolishing over eighteen tunnels.[3]


Small fire fights lasted the duration of Operation Beaver Cage. Three soldiers and four sailors were killed. It was estimated that forty Viet Cong were killed. The American soldiers seized a variety of guerrilla warfare provisions ranging from AK-47 and ammo to AKM's and improvised grenades. The operation was considered a success.[4]
