Falklands War: the British Army defeats the Argentine Army at the Battle of Goose Green.

The Falklands War was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British Overseas Territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands. The conflict began on 2 April 1982, when Argentina invaded and occupied the Falkland Islands, followed by the invasion of South Georgia the next day. On 5 April the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel and three Falkland Islanders were killed during the hostilities.
