'For conspicuous gallantry and devotion to duty. At Auchonvillers on the Ancre on the morning of 26th Match 1918, Rifleman Sommerville's Company forward the screen while the Battalion was establishing an outpost line on a part of the front where the position was obscure. This man's section was on the flank of the screen, and on reaching the Sugar Factory on the Ypres Road they came in contact with the enemy. The Corporal in command of the section was sniped at and hit, his leg being broken. Rifleman Sommerville with another man immediately went to his assistance, bandaged his wound, and attempted to carry him out of danger on an oil sheet. They got him as far as a trench but found the enemy coming down the trench in force. In turns they carried the Corporal fifty yards along the trench, the one covering the other with rifle fire. Reaching a bend in the trench they jumped quickly out and into a shell hole, taking the Corporal with them. Here they remained on guard until nightfall when they obtained assistance and took the Corporal to the Aid Post. Throughout they were under heavy fire, the Corporal being again wounded twice in the arm. The great resource and coolness displayed, together with the entire contempt of danger shown by Rifleman Sommerville, were an inspiration to those who witnessed this commendable exploit.'
