Was Edmund at Vicksburg?

Family stories say that Karen’s great grandfather lied about his age in order to sign up to fight for the Confederacy even as his father was an officer in the Union army. Records we found on the Fold3 website indicated he fought and was taken prisoner at Vicksburg. When we visited the national military park we found that trying to learn where he fought was an exercise in frustration. It will require more research more research and a return visit. On the other hand by listening to the ranger talk at the USS Cairo Museum, we learned a lot about ironclad battleships on the Mississippi River.
