Web Author's Notes:
This beautiful lithograph shows a view of the battlefield looking from the country road that ran northeast of Vicksburg along the base of Chickasaw Bluffs.  Chickasaw Bayou can be seen in the midground, looking north toward the Yazoo River, the area dotted with stands of woods and sloughs and frequently covered with abatis laid by Confederate troops in anticipation of an attack. Union troops, including the 16th OVI, crossed over the bayou, attempting to storm the Rebels entrenched in the bluffs and protected by heavy timber.  The union troops, as can be seen in the drawing below, were completely exposed as well as being bogged down by the bayou and the trees and brush covering the open land on each side.
