Operation Rosario (Falklands/Malvinas War)
On April 2, 1982, with an armed confrontation in the making between a platoon of British Royal Marines (under Lieutenant Keith Mills and Sergeant Peter Leach) sent to reinforce the British Antartic Survey (BAS) under base commander Steve Martin and apprehend Argentine scrap-metal workers on South Georgia and their protecting Special Forces from the Argentinian Navy survey ship ARA "Bahía Buen Suceso", Argentina invaded the Falkland/Malvinas Islands, a remote British colony in the South Atlantic. The Argentinian amphibious landings, Operation Rosario (under Rear-Admiral Carlos César Büsser, Argentinian Marine Corps Commandant), led to a brief, but costly war.
Argentinian invasion plans accelerated when Britain protested about the presence of scrap-metal workers on South Georgia. With talks on the future of the Falklands stalled, the Argentinian Military Junta reacted strongly and by March 26, 1982, two frigates were on their way south, and more ships had put to sea ostensibly for exercises with the Uruguayan Navy. But it seemed that only now was the final decision taken to invade and they headed for Stanley although bad weather delayed their arrival. By March 31, British intelligence had to assume landings were imminent, Governor Rex Hunt was warned, and next evening he announced over the radio that invasion was expected early on April 2.
Before the broadcast took place, the defence of Port Stanley was already being organized by the company-sized garrison of Naval Party 8901 (NP8901, all volunteers from 42 and 45 Commandos), under Major Gary Noote and Falkland Islands Defence Force (FIDF, Royal Marines-trained), under Major Phil Sommers. Usually consisting of 160 defenders, Majors Noote and Sommers, had been reinforced by Major Mike Norman and his platoon-sized garrison replacement that had disembarked from the RRS "John Biscoe". Assuming the main landing would be near Stanley Airfield followed by an advance on Port Stanley, Noote, Sommers and Norman deployed their 120 men accordingly, and positioned four sniper/anti-tanks squads on the Airport Road ready to fall back on the main 40-man position at Government House. By the early hours of April 2, they were mostly in position and the small patrol ship "Forrest" was out in Port William on radar watch. Governor Hunt also ordered the arrest of 30 Argentinian workers from Gas del Estado.
The plan was for the 1st Amphibious Commando Grouping (APCA) under Lieutenant-Commander Guillermo Sánchez Sabarots to attack both the NP8901 Barracks at Moody Brook and Government House to force a surrender, supported if necessary by men of Commander Alfredo Raúl Weinstabl's 2nd Marine Infantry Battalion (BIM 2) landed from ships of Task Group 40.1. Under the command of the 1st Marine Brigade commander, Captain Miguel Angel Pita, the Argentinian Marines had orders to cause no casualties "if at all possible". Once Stanley Airfield was in Argentinian hands, the 25th "Special" Infantry Regiment (Army Rangers) and Special Operations Group (Air Force Commandos) would then fly in.
The first landings were before midnight with the 1st Amphibious Commando Grouping spearhead under Lieutenant Bernardo Schweitzer going ashore from the destroyer ARA "Santisima Trinidad" to secure Mullet Creek, followed early on Friday morning by a Buzo Tactico beach reconnaissance party from the submarine ARA "Santa Fe" to check out the main landing beach north of Stanley. As the Amphibious Commandos secured their objectives the destroyers and frigates of Task Force 40 took up support and escort positions and the Tank Landing Ship ARA "Cabo San Antonio" headed in for the unguarded beach at York Bay.
From 6:00 a.m. the main Special Forces attacks and supporting infantry landings got underway. The larger body of Amphibious Commandos cleared Moody Brook and then headed east for Government House which by then was under fire from the spearhead under Lieutenant-Commander Pedro Edgardo Giachino. Giachino, Second-in-Command of the 1st Marine Infantry Battalion (BIM 1), was hit by small arms fire during the attack on Government House and died of his wounds, becoming the only Argentinian invasion force fatality that was treated at the local King Edward VII Memorial Hospital. Around 6:30 a.m., the first of some 20 LVTP-7 Amtraks with 20 or more Marines each inside were landing from "Cabo San Antonio" and by 6.45 am more Marines from the 1st Marine Infantry Battalion were coming into the airfield by Sea King helicopters. A 25th Regiment platoon under 2nd Lieutenant Oscar Roberto Reyes, having disembarked from VAO 010, cleared the Airfield buildings.
As the outnumbered NP 8901 and FIDF defenders fell back on Government House, one of the squads under Lieutenant Bill Trollope defending the Ionospheric Research Station on the Airport Road, stopped the Amtrack spearhead (VAOs 05, 07 and 019) with anti-armour weapons, machine-guns and sniper fire that wounded one Argentinian Marine, Private Horacio Tello. The spearhead was brought to a halt by machine-gun fire hitting the driver compartment of 2nd Sub-Officer Anibal Edgardo Esposito and turret of VAO 7, forcing the machine-gunner, Corporal Osvaldo César Arce to take cover. None of the occupants of VAO 7 were seen to emerge for 2nd Sub-Officer Víctor Quiroga under the guidance of Arce, manoeuvred the Amtrack off the road into a hollow in the ground and disembarked the Marines now hidden from view. But the Royal Marines were obliged to fall back as the Argentinian Marines emerged from the other Amtracks and 2nd Sub-Officer Mario Di Filippo's VAO 19 opened fire with a 72mm recoilles rifle, scoring a direct hit on the building.
Only one Royal Marine squad under Corporal Lou Armour' managed to fight its way to Government House, the others were gradually overrun by the increasing number of Amtracks and Marines landed by the white-painted Sea King and Lynx helicopters.
With daybreak and Government House surrounded, under sniper fire and the Amtracks approaching, Governor Hunt attempted to negotiate. Faced with the overwhelming forces at Rear-Admiral Büsser's disposal, he ordered the defenders to lay down their arms, which they did at 9:30 a.m. without having suffered any casualties. The Royal Marines had held out against two Argentinian Marine battalions and Special Forces for three hours, firing 6,450 small-arms rounds and 12 anti-tank rocketsin a firefight that cost the life of the 2ic of BIM 1 and wounded five invaders, including a military chaplain (Natalio Astolfo) and an Army NCO that stepped on a mine or booby-trap. According to one of Norman's men, Colour-Sergeant Bill Muir, "It was initially estimated that we had killed five and injured seventeen, but we only counted the bodies that we saw drop in front of us."
That evening, the Governor, his family and most of the Royal Marines and captured sailors from "Endurance" were flown out. Major Norman and his men volunteered to fight again with Juliet Company, 42 Commando, suffering four wounded in the final mountain battles.
On April 3, the 1st Marine Infantry Battalion captured South Georgia, 1,350 kilometres to the east of the Falklands. In that action, the Argentinian corvette ARA Guerrico was lured too close to shore and hit by anti-tank missiles from the 23-man Royal Marines platoon under Lieutenant Keith Mill and one Argentinian sailor, Corporal Patricio Guanca was killed in the action. Soon after this Argentinian setback, another two Marines, Privates Mario Almonacid and Jorge Aguila were killed and seven wounded when the Puma helicopter transporting their platoon was hit by concentrated small-arms fire and forced to make a crash-landing. However, one British Royal Marine was wounded in an exchange of fire with the Argentinian Marines. The Marines platoon under Lieutenant Mills eventually surrendered when their position was bombarded by the Guerrico's main 100mm gun.
The 13-strong volunteer militia force under BAS commander Steve Martin at King Edward Point had taken refuge in the church at Grytviken; they were captured in the afternoon and were removed at gunpoint to an Argentine ship bound for Rio Grande, Tierra del Fuego, and held for 15 days before being repatriated to Britain. Thirteen other BAS men in South Georgia and two females, scientist Cindy Buxton and journalist Annie Price, remained in hiding until liberated by the British Task Force in late April 1982. They would later confirm that Lieutenant Mills had given them a pistol and that both women had been trained how to shoot.
Photographs of the Royal Marines outside Government House, facedown on the ground, soon appeared in the British press, smuggled out by out by Rex Hunt's son Tony for Simon Winchester of the Sunday Times who had taken the pictures. In response to calls for actions, British Prime Minister Margaret Thatcher ordered that an armada of British warships be sent to the Falklands. Winchester went to Argentina to cover the war from the southern airbases, but he was arrested with two colleagues (Ian Mather and Tony Prime) for spying.
Fierce battles erupted in May. In all, more than 900 soldiers and sailors from both side died in the fighting. But the British forces won. Winchester, Mather and Prime were freed on June 29.

- "The fact that no one was observed to emerge from the first Amtrac to be engaged encouraged the Royal Marines to think that one of their rocket rounds had punched a hole in it and that some of the machine-gun fire had penetrated the hole and caused severe casualties among the men inside. Local civilians who observed the action optimistically supported this view later. There was no rocket hit, just the scars of ninety-seven machine-gun bullets. Only one Argentine marine was slightly wounded by a sliver of metal cutting his hand." Argentine Fight for the Falklands, Martin Middlebrook, p. 37, Pen and Sword, 2003

We were still following our orders not to inflict casualties. The first round was about a hundred metres short, but the second hit the roof ...
