​History: Fire, Iron, and the Battle of Fort Davidson

​The iron furnaces of Pilot Knob were established around 1848 and became a vital industrial hub for the Union during the Civil War. The iron produced here was transported via the Iron Mountain Railroad to St. Louis to bolster the war effort.

​The furnaces were at the heart of one of the bloodiest encounters in Missouri: the Battle of Pilot Knob on September 27, 1864. Confederate Major General Sterling Price led a massive assault on the Union\'s Fort Davidson. During the retreat and subsequent raids, the original furnace was destroyed. It was rebuilt in 1865, and mining operations continued to shape the region for over 130 years, eventually transitioning from surface to deep underground mining before concluding in the late 20th century.
