On June 14, 1982, Argentine General Mario Menéndez surrendered his forces to British Major General Jeremy Moore at Port Stanley, ending the Falklands War. The conflict, sparked by Argentina's April invasion of the British territory, cost roughly 900 lives on both sides and reshaped politics in both nations, hastening the collapse of Argentina's military junta and bolstering Margaret Thatcher's standing in Britain.
The Falklands War had lasted just 74 days, but it ended with a scene of stark humiliation for Argentina. On June 14, 1982, General Mario Menéndez, commander of the roughly 10,000 Argentine troops occupying the windswept capital of Port Stanley, signed the instrument of surrender to British Major General Jeremy Moore inside the governor's residence.
The war began in April when Argentina's military junta, led by Leopoldo Galtieri, invaded the British-held Falkland Islands, partly to whip up nationalist fervor and distract from a collapsing economy. Britain, under Margaret Thatcher, dispatched a naval task force across 8,000 miles of ocean, a logistical gamble many doubted would succeed.
Fierce fighting at sea, in the air, and on the islands' peat bogs killed 649 Argentines and 255 British troops before the Argentine garrison, exhausted and outmaneuvered, finally capitulated. The defeat discredited the junta beyond recovery, triggering mass protests and the collapse of military rule in Argentina within a year. In Britain, the victory transformed Thatcher's political fortunes, cementing her image as the 'Iron Lady' ahead of a landslide re-election in 1983.
