Falkland Islands War, 1982, a war between Great Britain and Argentina over control of the Falkland Islands, a British colony in the South Atlantic. The colony had long been claimed by Argentina, which calls the islands the Malvinas.

The war began when Argentine forces invaded and occupied the Falklands April 2, and the nearby South Georgia Islands the next day. On April 5, Great Britain sent an expeditionary force to retake the islands. The British fleet arrived in late April and troops recaptured the South Georgias on April 26. Argentina sent waves of fighters and bombers from the mainland to battle the British fleet and carrier-based air force in an unsuccessful attempt to prevent British landings on the Falklands. The first troops were put ashore on May 21, and on June 14 the Argentine troops, about 11,000, surrendered.

Losses from the war included 277 British lives, about 1,200 Argentine lives, five British ships, an Argentine cruiser, and dozens of aircraft on both sides.
