The CWSAC boundary incorrectly identified actions and lands on the south side of the James River as associated with the May 15, 1862, US naval attack on the CSA fortifications at Drewry’s Bluff.
The revised Study Area is limited to the portion of the works and troop positions on the bluffs, and the stretch of river within accurate range of the Confederate guns where the Federal flotilla maneuvered and anchored during the engagement.
