On 27 October 1942, at El Aqqaqir (Kidney feature), Western Desert, Egypt, during the Second Battle of El Alamein, Lieutenant Colonel Turner was commanding a battalion of the Rifle Brigade. After overcoming a German position, the battalion fought off desperate counter-attacks by 90 tanks, destroying or immobilising more than 50 of them. During the action, one of the 6-pounder guns was left with only one officer and a sergeant, so Colonel Turner joined them as loader, and between them they destroyed another five tanks. Not until the last tank had been repulsed did he consent to having a wound in his head attended to.
