The British depended on complex logistical arrangements to recapture the Falkland Islands in 1982, as the British forces were operating 13,000 kilometres (8,000 mi) from home. The Royal Navy’s ships were augmented by ships taken up from trade (STUFT), and a base was developed on remote Ascension Island. The 3rd Commando Brigade was landed in May on East Falkland, but struggled to build up its supplies as the Argentine air forces made repeated attacks on ships. SS Atlantic Conveyor was struck by a missile, and sank with Chinook and Wessex helicopters (example pictured) on board, along with vital stores. This forced the 3rd Commando Brigade to yomp across East Falkland.
