Throughout the Revolutionary War, David Glenn served as a hunter and soldier under General George Rogers Clark, accompanying him on his extraordinary expeditions to Kaskaskia and Vincennes during Clark's Illinois Campaigns in 1778-79. He was responsible for procuring supplies for Harrodsburg, maintaining a small cabin to store meat and provisions about 50 miles south of the fort on Russell Creek. This area eventually bore Glenn's name, originally called Glennsville and later known as Glens Fork, and it became a thriving town until suffering hard times and near-abandonment during the Civil War.
