Explanation:

Anchored at Bahia on October 7, [the CSS] Florida, while her captain was ashore with half his crew, was caught defenseless in an legal night attack by Commander Napoleon Collins, of the U.S. Navy steam sloop-of-war USS Wachusett. Towed to sea, she was sent to the United States as a prize, despite the Empire of Brazil’s protests at the violation of its sovereignty. Commander Collins was court-martialed and was convicted of violating Brazilian territorial rights, but the verdict was set aside by United States Secretary of the Navy Gideon Welles. Collins won fame and eventual promotion for his daring capture of the raider.

At Newport News, Virginia, on November 28, 1864, Florida reached the end of her career when she sank under dubious circumstances after a collision with the United States Army Transport USAT Alliance, a troop ferry. Florida could therefore not be delivered to Brazil in satisfaction of the final court order, and could not rejoin the Confederate States Navy.
