Web Author's Notes:
These slightly more detailed maps, drawn by E. A. Munn from General Morgan's map of the battlefield, show the movements of the Union forces from their landing at the Johnson Plantation on December 26, 1862, to the primary battle clash on December 29, in the fields and bayous below Chickasaw Bluffs. The 16th OVI was part of Col. John DeCourcey's brigade under General G. W. Morgan.

The following maps taken from History of the Thirteenth Regiment Illinois Volunteer Infantry, prepared by a committee of the regiment, 1891, Chicago; Woman's Temperance Publishing Association, 1892
