America's fortress : a history of Fort Jefferson, Dry Tortugas, Florida
"America's Fortress is the history of a little-known military outpost and prison that has stood at the western extreme of the Florida Keys for over 150 years. Once known as the "American Gibraltar," Fort Jefferson on Garden Key was the most heavily armed coastal defense fort in United States history. When new naval guns made the massive but still incomplete fort obsolete, Fort Jefferson became the nation's leading maximum-security prison, holding several of the accused conspirators in the Lincoln assassination."
