The squadron off the bar
The dispositions of the blockading vessels off Charleston in mid-May 1862 put steamers on the main channel, at Rattlesnake Shoal, off Stono Inlet and off Bull’s Bay — an arc that had to be held day and night against pilots who had grown up on this water. Two days later one of those pilots took a Confederate steamer straight through it.
