A Bess with silver mounting and a gold touch-hole from the Battle of the Great Cacapon?

"The remains of a gun of high finish, ornamented with silver mounting and gold touch-hole, were plowed up near the battle ground about forty years ago. It was supposed to have belonged to a French officer. Part of a bomb shell was also found."

This is what Kerchival states in his book, A History of the Valley of Vrginia. He found this story from "Mr William Carlile now ninety-five years of age, and who resides near the battleground, informed the author that he removed and settle on Capon soon after the battle was fought. He also said that he had frequently heard it asserted that Morgan was in the battle, and acted with great bravery, &c. Mr Charles Carlile, son of the venerable man, stated the fact of the gun and part of a bomb shell being found.

David Pancake mentioned the existence of a gun found not as described above but that it was allegedly from this Battle of the Great Cacapon

Is any of this true?

We cannot confirm or disprove the existence of a gun found from that battle. We do think such a gun --- if it exists --- was not used in the battle. Look how dirty it gets in this picture? Is it that the same gun David Pancake heard of? We don't know.

The first edition of Kercheval's A History of the Valley of Virginia

.was published in 1833, so the digging up of the musket would have occurred circa 1793.

We know for sure, that Daniel Morgan, did not participate in the battle. He was convalescing from a wound through his mouth, resulting in a loss of teeth. He was shot by an Indian chasing him the day before the battle.

See story on that:

What is a touch hole?

The touch hole is the hole in the barrel of this brown bess just above the pan. You put black powder in the pan. When the flint hits the frizzen a spark is created. The spark flies into the pan full of black powder. That pan of black powder in the pan ignites and its sparks fly into that hole (touch hole) in the barrel where black power if waiting behind a lead ball to explode out of the barrel.
