English: Map of battlefield core and study areas.

The ABPP revised the 1993 Study Area and extended the Confederate approach route to Marshville where Porter and Marmaduke's forces met prior to moving east. The Confederate flanking maneuver around Merrill's position at Wood's Fork, the Confederate route of retreat toward Houston, and the Union route of retreat towards Lebanon were also added to the Study Area.

The ABPP added a new Core Area at Wood's Fork where Federal and Confederate forces first clashed. The Core Area at Hartsville was adjusted slightly to better represent the range of artillery used by both forces.
