SAS Raid: Pebble Island made the headlines during the Falklands war when British Special Forces attacked the airfield where Argentina had established a small air base. This highly successful raid, carried out by D Squadron of 22 Regiment, Special Air Service, took place on the night 14/15 May 1982. It was the first land-based action of the campaign and resulted in the destruction of 11 Argentine aircraft. Today, fly-in visitors to Pebble Island land on the same airstrip that was raided by the SAS in 1982. A small cairn commemorates the action.

H.M.S. Coventry: On 25 May 1982 Argentine jets bombed and sunk this British Type-42 Destroyer 11 miles north of Pebble Island, where she was positioned as a radar picket. A large memorial cross erected by survivors on a scenic hill side not far from the settlement, looks out to where Coventry sank, and commemorates the 20 crew that died.

Argentine aircraft: North-East of First Mountain there are two crash sites with the scattered wreckage of Argentine Daggers. These multi-role fighter/bombers were both shot down by Royal Navy Sea Harriers in May 1982. Further to the west near Marble Mountain, a memorial commemorates 5 Argentine airmen whose Learjet crashed in the area after it was hit by a Sea Dart missile fired from HMS Exeter on 7 June 1982.
