During the Civil War, the port was the major base for Confederate and privately owned blockade runners, which delivered badly needed supplies from England. The Union mounted a blockade to reduce the goods received by the South. The city was captured by Union forces in the Battle of Wilmington in February 1865, approximately one month after the fall of Fort Fisher had closed the port. As nearly all the military action took place some distance from the city, numerous antebellum houses and other buildings survived the war years.
