On the night of 13/14 June 1982, on the Island of east Falkland, the 2nd Battalion Scots Guards attacked well entrenched enemy position on the craggy ridge feature of Tumbledown Mountain, seven kilometers to the West of Port Stanley
During the assault, leading elements came under intense fire from enemy snipers. A number of casualties were incurred. Disregarding his own safety, Lance Corporal MACCOLL went forward to administer first aid. As he was recovering a wounded colleague, along the way he took three enemy as prisoners. Again to the fore, continuing under heavy enemy artillery fire, he returned to recover other wounded men.
For his courage under fire, and his unselfish regard for his comrades, he is strongly recommended for Mention in Despatches.
