Operation Desert Rat (16 February – 3 April 1971) was a diversionary attack by a Laotian irregular regiment upon the crucial communist supply line, the

Bolovens Plateau
to the communist invaders.

Overview

Demilitarized Zone
dividing Vietnam.

The

lines of communications did not end ground assaults on the Trail. Indeed, Operation Desert Rat would be such.[1][2][3]

Background

Operation Desert Rat was launched on 16 February 1971 as a diversion to

North Vietnamese forces would be segmented from one another.[5]

Operation

Map of Operation Lam Son 719. Operation Desert Rat was staged west of Tchepone.

Operation Desert Rat began at Ban Houei Mun, which had also been both the start line and the after action rendezvous for the defeated troops of Operation Silver Buckle. When the regimental-size Groupement Mobile 33 (GM 33) mustered there, it was exposed to accounts of PAVN ferocity in the Silver Buckle fighting before being helilifted into action. As GM 33's troops loaded up at 0730 hours of 16 February 1971 on 14 helicopters of the 21st Special Operations Squadron, they came under communist rocket and mortar fire on the landing zone. However, they succeeded in departing on their mission.[4]

With 16 daily sorties of tactical air power taking advantage of the guerrillas' air superiority, and

South Vietnamese invasion, Lam Son 719.[4][6]

On 20 March 1971, GM 33 was slated to move down from its hilltop strongpoint and attack Moung Phine. Half an hour before their scheduled departure, GM 33 was struck by heavy weapons fire followed by an attack by two PAVN battalions. GM 33 held, but its commander lost radio contact with some of the subordinate units. After dark, guerrilla patrols began to infiltrate the Moung Phine Valley.[4]

Operation Lam Son 719 ended on 25 March. With that major distraction gone, the equivalent of a full

Army Corps was freed to turn on the irregular regiment. Savannakhet Unit of the CIA, which was controlling the action, radioed in withdrawal plans for GM 33. However, the guerrillas had already split into three columns to return to base. Two of the columns rendezvoused at Moung Phalane on 29 March 1971. The third made it back to Savannakhet.[4]

Results

During the operation, GM 33 troops had recovered a list of 21 communist espionage agents in Moung Phalane from the corpse of a North Vietnamese military intelligence officer. All 21 agents were subsequently arrested by the Royalists while they held that town.[7]

Aftermath

On 3 April 1971, GM 33 moved to the rear at Nong Saphong. They left Moung Phalane defended by two battalions of GM 30.[7]

In the wake of Lam Son 719, Silver Buckle, and Desert Rat, the PAVN extended its territory westward into Laos toward the

Attopeu, Ban Houei Sai, Salavan, Paksong, Ban Thateng.[8] The Pathet Lao garrisoned the newly conquered Plateau, backed by three PAVN battalions.[5]
