Thanks Druzhina. That really fits, if you are referring to St.Martin of Tours. He had a famous story about him of how he was riding on his horse and met a beggar, and the saint (who was a soldier at the time) cut his cloak in half with his sword and gave one half to the beggar and kept the other half for himself.
This seems to be often represented as St.Martin turning backwards on his horse to face the beggar who stands at the horse's rear -
