No Mike, a real person. He was interviewed after the charge by a journalist and gave a somewhat embellished account of his heroics, but other survivors mention him, he definitely made the charge and return journey. He died about 1860 in India, of cholera, by which time he was digging graves to earn his grog. This guy would do anything for a drink, rather like some BFFS members I know!
Finished him now, so here he is, but I did leave off the bloodstains from the apron.
The hat? Looks like a weird tam-o-shanter, but i treated it as a rather misshapen forage cap.
