The Stone Fleet consisted of a fleet of aging ships (mostly whaling ships) purchased in New Bedford and other New England ports, loaded with stone, and sailed south during the American Civil War by the Union Navy for the specific purpose of sinking and thus blocking the entrance into Charleston Harbor, South Carolina in hopes of preventing blockade runners from supplying Confederate interests. Although some sank along the way and others were sunk near Tybee Island, Georgia, to serve as breakwaters, wharves for the landing of Union troops, the majority were divided into two lesser fleets. One fleet was sunk to block the south channel off Morris Island, and the other to block the north channel near Rattlesnake Shoals off the present day Isle of Palms in what proved to be failed efforts to block access the main shipping channels into Charleston Harbor.[1]
Various old ships, specifically purchased by the Navy for this purpose, were loaded with stone and sand, or filled with dirt, then towed to a designated spot and sunk as a hazard to all craft that passed. Twenty-four whaleships were sunk in Charleston Harbor by Captain Charles Henry Davis, beginning on 19 December1861. A second fleet of 12 to 20 vessels was sunk in nearby Mafitt's Channel in 1862. The operation was under the direction of Samuel Francis DuPont, Flag Officer commanding the South Atlantic Blockading Squadron. Confederate general Robert E. Lee called the measure "an abortive expression of the malice and revenge" of the North.
Historians disagree as to the success of the Stone Fleet, since other channels of the Charleston Harbor remained open and the ships broke up in a year or two. However, others note that sufficient time was given for the North to build more gunboats to patrol the harbor.
The event inspired Herman Melville to write the poem entitled, "The Stone Fleet".
