July 19, 1972

The small fishing village was still dozing under the monsoon’s early morning mist. A half-mile to the north, behind a small hill, 250 adoo advanced in silence. No sound came from their cloth-muffled Chinese webbing. Their brand-new Russian AK-47s were well-oiled, their RPGs and 12.7mm heavy machine guns amply furnished with ammunition, their radios tuned to the correct frequencies, their recoilless artillery and mortars properly sighted. They were coming for revenge.

Last year’s defeat in Operation Jaguar had been nearly catastrophic to the Popular Front for the Liberation of the Arabian Gulf’s (PFLOAG) cause. The Dhofaris had begun to question their authority. Fear of punishment and promises for an equal society no longer carried the same weight. A credible victory was needed urgently.

Enter Mirbat.

Home to a firqat of around fifty men, its nine-man British Army Training Team (BATT) from B squadron SAS, and less than forty local gendarmeries, Mirbat’s sole attraction was its medieval fort. Already small, the garrison was further weakened by the absence of the firqat, which was patrolling on the nearby Jebel.

Even worse, what forces remained were divided. The gendarmeries, with their ancient .303 bolt-action rifles, were inside the fort, 700 yards to the northeast of the village, and in a small picket 1000 yards to the north of the perimeter. The SAS troopers, with their two mortar tubes, two GPMGs, and 0.50 Browning heavy machine gun, were on the BATT house 200 yards north of the village. A gun-pit, with an obsolete 25-pound artillery piece, lay adjacent to the fort.
