"Submerged Discoveries: Underwater Hospital and Cemetery Found off Florida Keys"

Archeologists have discovered the remains of a 19th-century quarantine hospital and cemetery on a submerged island in the Dry Tortugas national park, off Florida in the Gulf of Mexico. The site may contain dozens of graves, mostly of US soldiers stationed at Fort Jefferson. The fort was a military prison during and after the American civil war, hosting among other famous prisoners Samuel Mudd, a doctor who treated John Wilkes Booth, the assassin who broke his leg jumping to the stage of Ford’s Theatre in Washington DC after killing Abraham Lincoln.
