On April 2nd 1982, Argentina invaded and occupied the Falkland Islands. Argentina asserted that the islands are Argentine territory. 

Three days later, 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 just over ten weeks and ended with an Argentine surrender on June 14th, returning the islands to British control.  

In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders died during the hostilities.
