The Charleston Light, located on Morris Island, at the entrance to the harbor of Charleston, S. C., was one of the colonial lights turned over to the Federal Government under the terms of the act of August 7, 1789. The light was in a brick tower, built by the Colony of South Carolina in 1767. On May 7, 1800, Congress appropriated $5,000 for repairing the lighthouse. In 1838 the light was described as a revolving light, the tower being 102 feet from the base to the lantern. A new first-order lens was installed in the tower on January 1, 1858. [Illustration] On December 20, 1860, on receiving reports from the lighthouse inspector at Charleston regarding the probable seizure of the lighthouse property by the Confederacy, the Secretary of the Lighthouse Board wrote the Secretary of the Treasury that he would not recommend “that the coast of South Carolina be lighted by the Federal Government against her will.” Ten days later the inspector at Charleston informed the Board that “the Governor of the State of South Carolina has requested me to leave the State. I am informed that forcible possession has been taken of the lights, buoys, etc., of this harbor, and that similar measures will be adopted in regard to all lights in the State.” Early in January 1861, the Rattlesnake Shoal Lightship was towed into Charleston and the lighthouse tenders were seized. By the latter part of April 1861, practically all lights were extinguished, lightships removed, and other aids removed or destroyed from the Chesapeake to the Rio Grande, with the exception of some of the lights on the Florida coast and reefs. In 1862 the Lighthouse Board reported “Charleston, lens and lantern destroyed.” In all, 164 lights were forcibly discontinued during the Civil War on the southern coasts. These were relighted from time to time, and by 1866, the greater part had been restored. The Charleston Channel was re-marked promptly on the occupation of the city by Union troops in February 1865. In 1865 the Lighthouse Board reported “that an almost total change had taken place, leaving no channel in the harbor as it was in 1860, and opening new ones.” Under this altered state of things it became necessary to establish lights temporarily at such places as would be useful guides through existing channels and omit all other.
