'For conspicuous gallantry and devotion to duty. On April 5th 1918, Sergt Thompson was in charge of a forward bombing post which held off a heavy enemy attack. On July 15th 1918, he handled half a Platoon with great skill and courage in an attack on Fusilier Trench capturing two machine guns. Again during the first 14 days of August 1918 he was in charge of the wiring of Rossignol Wood and in spite of continuous shell fire succeeded in erecting 800 yards of wire. His coolness and bravery have always been of a very high order.'

'For conspicuous gallantry and devotion to duty on October 8th, near Crevecouer. During the attack on the 8th October, and at a moment when the enemy advanced in large numbers towards our lines from Lesdain, it seemed as if a counter attack on our flank was imminent. Sergeant Thompson, with a small party, rushed towards the edge of a cliff but were held down by an enemy machine-gun. Sergeant Thompson then worked his way forward, shot the machine gunner in the head, and turned the gun on the enemy inflicting many casualties.'
