On 6 August 1944 near Sourdeval, France, Bates was commanding a Section. Upon discovering that the enemy had penetrated deeply in the area occupied by his section, Bates seized a light machine-gun and charged, moving forward through a hail of bullets. Although twice wounded, he was undaunted and continued firing until the enemy started to withdraw away from his fire. At that moment he was wounded for a third time — mortally. He still however continued to fire until his strength failed him. By this time the enemy had withdrawn and the situation had been restored, and the immediate thread to his platoon subsided. He died in hospital two days later.
