Inside Fort Monroe.

Officers' Quarters in the casemates of Fort Monroe, Virginia. Alexander Gardner (?) photograph ca. 1864. (Library of Congress)

Wasn't Jefferson Davis imprisoned in one of Fort Monroe's casemates?

 

[FarawayFriend]

Yes he was. This sketch is showing him there:

And to my relief I see a window! I had feared the officers quarters were deep inside the walls, without a window for daylight and ventilation ...
But probably Davis's prison quarters were less snugly than the officers quarters. His casemate was unheated and had an open window, so that even Union Surgeon John Craven recommended more humane quarters.

Well, it was probably damp and poorly ventilated but at least it was bombproof.
