USS Cumberland was lost on March 8, 1862, during the Battle of Hampton Roads, where she served in the U.S. Navy’s North Atlantic Blockading Squadron. She sank after being rammed by the Confederate ironclad CSS Virginia (formerly USS Merrimack) and went down with more than 121 men.
CSS Florida was a Confederate commerce raider which had been captured by the U.S. Navy in Brazil. Towed to United States as a prize despite Brazil’s protests, it was lost on Nov. 19, 1864, following a collision with a U.S. Navy troop ferry.
Both vessels are protected by federal law under the Sunken Military Craft Act of 2005, the Abandoned Shipwreck Act of 1987, and the Territorial Clause of the U.S. Constitution, which gives the U.S. government exclusive rights to its own property.
