When the Spanish squadron finally attempted to leave the harbor on July 3, the American forces destroyed or grounded five of the six ships. Only one Spanish vessel, the new armored cruiser , survived, but her captain hauled down her flag and scuttled her when the Americans finally caught up with her. The 1,612 Spanish sailors who were captured, including Admiral Cervera, were sent to Seavey's Island at the Portsmouth Naval Shipyard in Kittery, Maine, where they were confined at Camp Long as prisoners of war from July 11 until mid-September.
