The action is traced from Farragut's failed navy-only efforts to bypass the city, through Grant's botched series of canal schemes, to his brilliant series of maneuvers that left Pemberton and his garrison besieged for more than 40 days. Key Union and Confederate players are identified and the strategic circumstances that made Vicksburg the lynchpin of the Western Theater are described. Appendices include information about Vicksburg National Military Park, the Federal and Confederate Orders of Battle and the Medal of Honor at Vicksburg.
