Most of the Federal troops killed at Perryville were first buried in regimental plots, near where they had fallen. After the war, they were reinterred at the Perryville National Cemetery, which was located west of town. Since funding for this cemetery was never fully allocated, the Union dead were moved once more to Camp Nelson (the Perryville National Cemetery no longer exists). Since these soldiers were moved several times, most of the names/headstones were lost. Therefore, most of the Union dead from Perryville buried at Camp Nelson are listed as "unknown." I think that all of the Perryville dead are interred in section E. For more information on these burials, contact the Perryville Battlefield State Historic Site at 859-332-8631. Ask for the park manager, who knows more about the battle and aftermath than anyone. There is also an active preservation program there, and you can see their website at www.perryville.net. They recently added another 100 acres to the battlefield, so the park now encompasses about 600 acres.
