The yacht USS Gloucester

When I was young, I still had access to books dating from the late 19th and early 20th Centuries about naval history and ships. I remember reading about the yacht USS Gloucester, which served with the fleet off of Santiago, as I recall. The Gloucester was a 240ft vessel of 786 tons armed with 4-6pdr (57mm) and 4-3pdr (47mm) guns. The Gloucester had a speed of 17 knots, so it was fast enough to be useful.
