"On September 27th, 1918, when the leading company was halted near Boulon Wood by an enemy strong point Lt. G. T. Lyall executed a flank movement with his platoon and captured it together with prisoners and its guns. Later that day his much weakened platoon was held up by machine guns at the southern end of the wood. Lt. Lyall led forward his few remaining men, then rushed the position single-handed, killing the officer in charge, and took it with its machine guns, capturing numerous prisoners. Advancing, he secured his final objective and still more prisoners. On October 1st, near Blecourt, by skilful disposition of the weak company he then commanded, he overcame another strongly held position, seizing numerous guns and many prisoners. In these two days Lt. Lyall captured 3 officers, 182 other ranks, 26 machine guns and 1 field gun, and inflicted heavy losses on the enemy. He showed throughout most conspicuous bravery, high powers of command, and skilful leadership."
