Fort Jefferson (Ballard County, Kentucky)

Ballard County · Kentucky · American Revolutionary War

Quick BriefFort Jefferson was a small 18th-century stockade built in 1780 by Clark's Illinois Battalion during the American Revolutionary War. Built by George Rogers Clark as part of a settlement plan conceived by Governor Patrick Henry of Virginia and later pursued by Governor Thomas Jefferson, the fort was to protect the U.S. claim to its western border and serve as a key trading post. Clark ignored the requirement to purchase land from the Chickasaw, and historians point to this disregard as the point at which the fortification project was doomed to failure.

History & Significance

The construction of Fort Jefferson was first proposed during a Council of War meeting between Clark and his junior officers at the Falls of the Ohio (Louisville) on November 16, 1779. Construction began with about 150 soldiers on April 11, 1780, with help from the Kaskaskia.

By January 1780, Clark had surveyed the confluence area of the Ohio and Mississippi rivers and selected a location for the fort and town five miles south of the confluence on the east side of the Mississippi River. The construction of Fort Jefferson and the civilian town of Clarksville was completed in June 1780.

In 1781, the Chickasaws, led by Colbert, besieged the fort for five days, aroused by use of their land without consent. General Clark arrived with reinforcements and supplies, and the Indians withdrew.

On June 8, 1781, Fort Jefferson was evacuated and the troops arrived at Falls on the Ohio on July 12, 1781. Fort Jefferson and its Town of Clarksville were the only Virginian settlements built in Kentucky sanctioned by the Commonwealth of Virginia. The fort was briefly reoccupied during the Civil War era.
