While the Cannon-Pawn is similar in some ways to a piece in Four-Field Kono (the usual English name for the game), unlike it, they can capture by jumping over opposing pieces as well as friendly pieces. Now, I've been exposed to Four-Field Kono via one or another of R.C. Bell's books, so it could have been an influence, but the Cannon from Xiang Qi was a more immediate influence.
