First of all i love all your books, not only Sharpe i have a little question. After reading a book called From Corunna to Waterloo with The Hussars by John Mollo?
It mentions Charles Jones as the Red Dwarf. Looking at his military career and connection with Grant and of dates of promotions i am 100% certain that he is our man. He was adj to the king of Hańnover. Have you heard of him?
