Starting on April 2, 1982, the war cost the lives of 255 British service personnel, who died in the successful defence of the islands.
It also left 649 Argentine soldiers dead.
The conflict erupted after Argentina seized the island – overwhelming the small British garrisons at Port Stanley and in South Georgia.
Argentina claimed that the islands belonged to them, despite being under British rule for about 150 years.
In response to the invasion then-prime minster Margaret Thatcher deployed one of the largest British armadas to retake the islands more than 8,000 miles away.
