The screw steam frigate USS Pensacola was the backdrop for this Alexandria, Virginia waterfront scene by photographer James F. Gibson, circa 1861. Built in 1859 at Pensacola, Florida, the frigate later served with the flag officer David Glasgow Farraguts West Gulf Blockading Squadron and was the second ship in line during the historic run past the forts below New Orleans on 24 April 1862. She served for varying periods until finally struck from the Navy records in 1901 and burned by the Navy in San Francisco Bay off Hunters Point in May 1912.
