I printed that page from the VA website before I went and I'm glad I did. The Grave Locator at the cemetery allows you to print a cemetery map and I got one of those while there. There were a few gravesites in particular that I wanted to find. This was the first one. The only Medal Of Honor winner buried at Natchez National Cemetery.
"Wilson Brown was born into slavery in 1841 at Natchez, MS. During the Civil War, Brown escaped to the Navy gunboat USS Hartford and enlisted in 1863. Landsman Brown served until 1865, including aboard the Hartford, and returned to Natchez at war’s end. During the Battle of Mobile Bay (AL) on August 5, 1864, Brown was knocked unconscious in the ship’s hold by a shell burst. He regained consciousness and returned to supplying cannon ammunition. Brown was awarded the Medal of Honor for bravery. He died in January 1900 and is buried in Natchez National Cemetery (Section G, Grave 3152)."
