The Union navy, in concert with the army, captured several more coastal areas along the Atlantic seaboard and Gulf coast. Following the Union victory at Hatteras Inlet the previous year, other parts of the North Carolina coast, including New Berne, were captured; in April, Union forces attacked and captured Fort Pulaski in Georgia following a thirty hour bombardment, cutting off Savannah from blockade runners. This victory left Wilmington, North Carolina as the only major Atlantic port to remain in Confederate hands. Several ports in Florida and along the Gulf coast were captured as well, including Apalachicola and St. Augustine in Florida and Biloxi, Mississippi. In April, a Union squadron commanded by Commodore David Farragut ran past Forts Jackson and St. Philip near the mouth of the Mississippi River and forced the surrender of New Orleans, the largest Confederate port city in both population and in trade volume.
