The Falklands War was a ten-week undeclared war between Argentina and the United Kingdom in 1982.
Over two British dependent territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands.
The ongoing tension between the two countries over the islands increased on 19 March, when a group of Argentine scrap metal merchants (which had been infiltrated by Argentine Marines) raised the Argentine flag at South Georgia Island, an act that would later be seen as the first offensive action in the Falklands war.
The Argentine invasion of the British-held Falkland islands in the far south Atlantic began on 2 April 1982. It led to the deaths of 255 British military personnel, three islanders, and 649 Argentine soldiers during the 74-day conflict.
