Ironton - Fort Davidson State Historic Site

The valley was the scene of the Battle of Pilot Knob. Confederate Maj. Gen. Sterling Price invaded Missouri from Arkansas, leading an army of 12,000 men. On Sept. 26-27, 1864, while en route to the St. Louis area, Price attacked the weakly defended Union post of Fort Davidson at Pilot Knob.

Fort Davidson was defended by a garrison of 1,450 men led by Gen. Thomas Ewing Jr., the brother-in-law of Gen. William Tecumseh Sherman. The Confederates lost nearly 1,000 men in attacking the small earthen fort and its 11 cannons.
