Walnut Hills, Near Vicksburg, Mississippi
My sappers have built trenches that are closing on the walls of the fortress. The sappers use cane and cotton bundles to protect them from bullets fired from the fort above. A group of sappers in McPherson’s division used an old railroad flatcar as a barricade. They loaded the car with cotton bales to stop bullets Our sharpshooters and small artillery can operate behind the wall of cotton to keep the enemy sharpshooters from showing their heads.
