Military Medal 'Operations: British Front before Puisieux 14th August 1918. For conspicuous gallantry and devotion to duty. On the morning of the 14th August, when it was suspected that the enemy had evacuated their trenches in front of Gouzeacourt, Sergeant McMillan took out a patrol. He went straight for the known enemy posts, and finding the first evacuated dashed forward to the enemy's main line. He incurred great risk from snipers and machine guns. He sent back most valuable reports and kept going forward until he reached the Serre - Puisieux Road, when he came under heavy machine gun fire. This N.C.O. showed great dash, initiative and courage, and was a fine example of what a patrol leader should be.'
