A single page from Harper's Weekly reporting on General Grant's Vicksburg campaign, with letters from artist Theodore R. Davis describing the trenches, sharpshooting, and the army's approaches. It includes an account of a bridge built of cotton bales over the Black River by Major Hickenlooper's engineers. A shorter section on the Army of the Potomac describes the shelling of rifle-pits at the Rappahannock crossing. Engravings show the cotton bridge and the arrival of Vicksburg prisoners at Fort Delaware.
