hey Wilmington Mike, here is shrapnel from Whitehall, on the other side of the river up on the hill overlooking town, the Federals were located and at the point on the map where "privates Newsome and Lipscomb" were killed by the explosion of a confederate ball,I found this underplug and U S skin.They were right beside each other and the skin was real wadded up. It fit the underplug and even has thread marks . I thought it was a piece of a beer can and straightened it out. I was very surprised to see U S. I have always thought this was part of that ball and the skin came from one of those 2 guys boxplate or belt plate.
