Mount Tumbledown, Mount William, and Sapper Hill are located to the west of Port Stanley, the capital of the Falkland Islands. Due to their proximity to the capital, these positions held strategic importance during the 1982 Falklands War. On the night of 13–14 June, British forces launched an offensive against Mount Tumbledown and the surrounding high ground. The operation was successful, forcing the retreat of the Argentine force. This engagement, one of several night battles during the British advance toward Stanley, allowed British troops to secure a dominant position over the town, leading to the fall of Stanley and the surrender of Argentine forces on the islands.
