By Don Campagna, special to Charleston Currents | Following the Spanish-American War, the United States found itself in need of a global navy that could serve its new, far-flung empire.

In 1901, the decision was made to locate an East Coast base in Charleston and several Cooper River plantations, The Retreat and Marshlands, were purchased for that purpose. Work began almost immediately on the construction of a drydock and supporting trade shops. Additionally, a large coal-fired power steam plant in the Beaux Art style was built to provide electricity.
