The ABPP expanded the 1993 Study Area to include the town of Granby, from which Union forces marched to Newtonia, and the Confederate approach from Camp Coffee (based on the findings of a 1995 archeological survey funded by the ABPP). The Federal approach from a campsite approximately three miles north of Newtonia was also added (Union reenforcements from Sarcoxie retreated to these camps, but their exact route is not known and therefore not included on the map).
The ABPP expanded the Core Area to include the Confederate flanking attack along the Granby Road, and the area bombarded by the Federal artillery on the heights north and northwest of Newtonia.
