Very few visitors to the island ask about the Union soldiers who died doing their duty for their country. Even the records of these men are incomplete and very little can be found. In 1868 Quartermaster General Meigs in a letter to the Secretary of War, mentioned that there were 136 Union dead at Rock Island and he concurred with the recommendation of General L. Thomas that these bodies be removed to the upper part of the island. He did not concur on the removal of the Confederate dead to the same location. These Union dead were removed to the site recommended, the present Rock Island National Cemetery.
Nothing remains of the prison buildings today.
Visitors on the island, as they view the island's beautiful scenery, see nothing to recall this period in the island's history. Where once the Headquarters buildings of the prison was located stands the mansion of the Commanding General of the Ordnance Weapons Command. The stockade and the prison barracks area is now a part of the Rock Island Arsenal Golf Course and officers quarters. The non-contagious disease hospital is the present site of two Arsenal shop buildings. The pest houses of the day have given way to a huge shop building.
