This park preserves the battlefield where Union and Confederate troops fought on July 4, 1863. In this battle, Union soldiers from the 25th Michigan defeated a larger Confederate force. Confederate General John Hunt Morgan had just begun what would become an infamous raid that would take him into Kentucky and Indiana. Morgan expected an easy victory as his force of nearly 1000 men faced only two hundred Union defenders with no artillery. However, sharpshooters from the 25th Michigan decimated Morgan's artillery while the rest of the Union men fired behind well-fortified positions. Given his advantages, Morgan expected the 25th Michigan to surrender. Instead, Colonel Orlando Moore sent the following message back to Morgan: “Present my compliments to General Morgan, and say to him that, this being the fourth day of July, I cannot entertain his proposition.” In the ensuing battle, Morgan lost six times as many men as Moore.
Visitors to the area can view photographs, artifacts such as uniforms, and a diorama depicting the battle in the Atkinson-Griffin Log House which is at the Green River Lake Visitor Center a few miles to the east of the battlefield.
