Historical Marker at Washington Navy Yard: Serving As a Temporary Federal Prison

From HMdb.

Located in the Washington Navy yard in Washington D.C., on the side of the wall of a building.

On the marker:

"The body of John Wilkes Booth, assassin of President Abraham Lincoln, was brought to the Navy yard for  examination and identification aboard the monitor USS Montauk (which had been involved in operations on the Cape Fear River in February that led to the capture of Wilmington).

With the exception of Mary Surratt, the Lincoln conspirators (including Lewis Payne, shown in the picture) were temporarily imprisoned on board the USS Montauk and other naval vessels before being transferred to the Washington Penitentiary for trial."
