The BBC has an article on Adrian Carton de Wiart, a legendary British soldier. From the article:
Carton de Wiart served in the Boer War, World War One and World War Two. In the process he was shot in the face, losing his left eye, and was also shot through the skull, hip, leg, ankle and ear.
In WW1 he was severely wounded on eight occasions and mentioned in despatches six times.
Having previously lost an eye and a hand in battle, Carton de Wiart, as commanding officer, was seen by his men pulling the pins of grenades out with his teeth and hurling them with his one good arm during the Battle of the Somme, winning the Victoria Cross.
