Butler's Steamship Greyhound: The End

Admiral Porter described the Greyhound in his memoirs as deserving "her name, for she was a long, lean-looking craft and the fastest steamer on the river."

But it was not the fastest steamer for much longer.

Porter continued in his memoirs and wrote about her last voyage, a few miles below Bermuda Hundred, Virginia, "a torpedo" blew out the engine room and set the ship afire, the admiral, general, their staffs and crew  barely escaping as the Greyhound was "wrapped in flames from one end to another" in a final"grand spectacle."

Some Southern saboteurs had planted one or more torpedoes in the bunkers disguised as chunks of coal, which the stokers dutifully shoveled into the fires.
