I have seen a couple of other Ft. Meigs horns, carved by other hands than Francis Tansel, and not as accomplished. I am aware of the cup with fort drawing, but have not studied it closely to see how well it mimics the Tansel carved "Ft. Meigs" horn images. My guess, which is all we can go on these days, is that the layout of the fort was drummed into each soldier's head. Tansel was there for much of his 6 month enlistment period, so I would imaging he knew rather well the structure, shape, approx. dimensions, locations of gates, etc. of the fort, as well as the trenches dug inside it to protect soldiers from cannon/mortar shells. I would guess most images of Ft. Meigs carved on powder horns or cups were probably rather easy for Tansel, or others, to briefly sketch on the surface before carving. Actually in Francis Tansel's case, he at times sketched figures on paper first, then pin-pricked their outline on the horn to assist his carving accuracy. It would be interesting to study the Boswell cup and the Samuel Arnold horns' depictions of Ft. Meigs side-by-side, to see how closely they mimiced each other.
Another reason for thinking Tansel did his own design for Ft. Meigs images is that, on the two fully carved Ft. Meigs horns, carved a couple days apart, there are slight differences in the two images of Ft. Meigs, both in walls and in the internal trenches, suggesting he was doing the carving from his own recollections on the day he carved each horn.
