'Operations: British front line South of Hebuterne. For conspicuous gallantry and devotion to duty. On the 5th June 1918 Corporal Stewart acted as guide to a silent raiding party of 2 NCOs and 4 men, intending to raid a suspected enemy post 500 yards from our front line, Corporal Stewart had on three previous mornings reconnoitred the approach in broad daylight. The enterprise was completely successful. Two men watched the flank of the party while the remaining four, including this NCO, jumped the enemy wire fence into the trenches where they surprised two of the enemy, one evidently a sentry. The party then moved along about 15 yards and captured five more prisoners. They then returned to our lines, overland, with the 7 prisoners, and without suffering casualties. The success of the enterprise was largely due to the previous daylight reconnaissances of Corporal Stewart. These, and the enterprise, were carried out in full view of his Company, on whom it will have a splendid effect.'
