All the casualties caused in 4 Troop during the operations at Termoli between 3rd and 6th October 1943 occurred in the positions in the F.D.L. which were enfiladed by enemy tanks on the left. By the [illegible] machine gun fire had ploughed a track through the [illegible] in rear of our forward weapon pits and any movement along this fixed line brought a burst of fire, yet Trooper Rigg never hesitated to go forward immediately any casualty occurred. He dealt with five of our casualties in these conditions, often exposing himself for considerable periods while dressing them. His conduct throughout the operation was in accordance with the highest traditions of the R.A.M.C.
