Hand-drawn map in pencil labeled “Map of Vicksburg & Its Defences,” one page, 8 x 10, no date but circa 1863. The sketch shows a bird's eye view of Vicksburg and the surrounding battlefield, with a legend on the right listing several of the features depicted, including: “Harris Bluff,” “Rebel Camp,” “Battle ground,” “United States troops,” and “Road to Richmond.” The Mississippi River is also prominently featured in the map. The reverse also bears a pencil sketch of the defenses at Charleston Harbor, labeled below (spelling retained), “Sean By an ie witnes Chaleston South Carolina.” In very good condition, with intersecting folds, foxing, and soiling.
