Following [[Operation Rosario (Falklands/Malvinas War)]],  the Argentinian occupation of the Falkland/Malvinas Islands, 42 Commando and 45 Commando (40 and 45 CDO) of the British Royal Marines were deployed as part of Brigadier Julian Thompson's 3 Commando Brigade to retake the islands in Operation ''Corporate''.  

During the 1982 [[Falklands/Malvinas War]] the battle for the high ground on Mount Harriet and neighbouring Two Sisters Mountain was pivotal to both British attackers and Argentinian defenders as both sought to secure the approaches to Port Stanley. The battle began on the night of May 29th, 1982 but didn’t reach its conclusion until June 12th and, even then, only after several heavy British naval bombardments as well as Royal Air Force Harrier attacks and Royal Marine Commando ''raids''.
