During the Civil War, the Tannehill Furnaces shipped 22 tons of pig iron daily to the Selma Arsenal and Gun Works. Sent by wagon to the railhead at Montevallo, then on the North & South RR to Selma, Tannehill iron went into various castings from naval plate to artillery shells. The iron works were attacked by three companies of the US Eighth Iowa Cavalry as part of Wilson's Raid in Alabama on March 31, 1865, when production ceased. Today, they are among the best preserved Civil War era iron blast furnaces in the US.
