Two Royal Marines of 3 Commando Brigade "blacked up" and ready to board a landing craft at the start of Operation SUTTON, the landings at San Carlos Bay, Falkland Islands, 21st May 1982.
After the Argentine invasion of the Falkland Islands the United Kingdom initiated Operation Corporate sending a Task Force 12000 km south in order to retake the islands. Under the codename Operation Sutton the British forces planned amphibious landings around San Carlos, on an inlet located off Falkland Sound, the strait between East Falkland and West Falkland. The location was chosen as the landing force would be protected by the terrain against Exocet and submarine attacks, and it was distant enough from Stanley to prevent a rapid reaction from Argentine land troops stationed there.
The landing took the Argentines completely by surprise; Argentine Navy officers had considered that the location was not a good choice for such an operation, and had left the zone without major defences. It was the first time in history that a modern surface fleet armed with surface-to-air missiles and with air cover backed up by STOVL carrier-based aircraft defended against full-scale air strikes. The British sustained severe losses and damage, but were able to create and consolidate a beachhead and land troops. During the night on 21 May the British Amphibious Task Group under the command of Commodore Michael Clapp (Commodore, Amphibious Warfare – COMAW) mounted Operation Sutton, the amphibious landing on beaches around San Carlos Water, on the north western coast of East Falkland facing onto Falkland Sound. The bay, known as Bomb Alley by British forces, was the scene of repeated air attacks by low-flying Argentine jets. The 4,000 men were put ashore as follows: 2nd Battalion, Parachute Regiment (2 Para) from the RORO ferry Norland and 40 Commando Royal Marines from the amphibious ship HMS Fearless were landed at San Carlos (Blue Beach), 3rd Battalion, Parachute Regiment (3 Para) from the amphibious ship HMS Intrepid were landed at Port San Carlos (Green Beach) and 45 Commando from RFA Stromness were landed at Ajax Bay (Red Beach). Notably the waves of eight LCUs and eight LCVPs were led by Major Ewen Southby-Tailyour, who had commanded the Falklands detachment NP8901 from March 1978 to 1979. 42 Commando on the ocean liner SS Canberra was a tactical reserve. Units from the Royal Artillery, Royal Engineers, etc. and armoured reconnaissance vehicles were also put ashore with the landing craft, the Round table class LSL and mexeflote barges. Rapier missile launchers were carried as underslung loads of Sea Kings for rapid deployment. By dawn the next day they had established a secure beachhead from which to conduct offensive operations. From there Brigadier Julian Thompson's plan was to capture Darwin and Goose Green before turning towards Port Stanley. Now, with the British troops on the ground, the Argentine Air Force began the night bombing campaign against them using Canberra bomber planes until the last day of the war (14 June).
