If you are talking about the Seventh Kentucky Infantry, CSA, that was organized at Camp Burnett, Kentucky, Shiloh was their baptism of fire. As a US military veteran and a researcher of the Seventh Kentucky Infantry, CSA, and the other Confederate units from the Jackson Purchase of Kentucky, the Confederate Government never had the word "mounted" made as part of the official military designation of this regiment or any other. The Confederate Government had ordered for certain infantry units to be mounted on horses but did not authorize a name change for the unit. Don't believe what the Federal Government has designated some Confederate infantry regiments on the microfilmed service records.
