USS "Bennington" (Gunboat No. 4) was commissioned at the New York Navy Yard on 20 June 1891 under the command of Commander Royal B. Bradford. As one of the first steel-hulled gunboats of the "New Navy", "Bennington" was assigned to the Squadron of Evolution, a unit made up entirely of "New Navy" ships that was established to test and perfect tactics and doctrine developed at the Naval War College. In addition to operating as the first tactical fleet of the U.S. Navy, the squadron performed the secondary mission of cruising to foreign ports to demonstrate to the world the types of modern ships the United States was capable of building. In that latter role, "Bennington" and the rest of the squadron departed New York on 19 November 1891 for the unit's cruise to Brazil.
