On 1 September 1918 at Péronne, Somme, Hall rushed a machine-gun post, shooting four of the enemy and capturing nine, with two guns. Continuously in advance of the main party, he personally led assault parties, capturing many small parties of the enemy and machine-guns. On the morning of 2 September during a heavy barrage, he carried to safety a comrade who had been dangerously wounded and was in urgent need of medical attention. It was for these actions that Hall was awarded the Victoria Cross.
