Malvern
From Tardis Wiki, the free Doctor Who reference
The Malvern was the ship that transported President Abraham Lincoln to Richmond, Virginia, in early April 1865, following the departure of Jefferson Davis and the rest of the Confederate government from the city. (PROSE: Blood and Hope)
Behind the scenes
The ship was prefixed "USS" in the real world — and logically would have been in the DWU as well — but Blood and Hope doesn't give that specific detail.
