Wales-born Richard William Leslie Wain was awarded the Victoria Cross after his actions on November 20, 1917, during the Battle of Cambrai.
Born in Penarth, near Cardiff, Wain had fought on the first day of the Battle of the Somme with the 17th Battalion of the Manchester Regiment.
He had been wounded during the fighting for the village of Montauban.
He later joined the Heavy Section of the Machine Gun Corps which was equipped with tanks and took part in the Battle of Messines in June 1917.
In November 1917, aged 20, he was a section commander and acting captain in A Battalion, Tank Corps, when he took part in fighting at Marcoing, near Cambrai.
The citation for his Victoria Cross reads:
“For most conspicuous bravery in command of a section of Tanks. During an attack the Tank in which he was, was disabled by a direct hit near an enemy strong point which was holding up the attack. Capt. Wain and one man, both seriously wounded, were the only survivors. Though bleeding profusely from his wounds, he refused the attention of stretcher-bearers, rushed from behind the Tank with a Lewis gun, and captured the strong point, taking about half the garrison prisoners. Although his wounds were very serious he picked up a rifle and continued to fire at the retiring enemy until he received a fatal wound in the head. It was due to the valour displayed by Capt. Wain that the infantry were able to advance.”
