Beck’s Mill is a historic gristmill in Washington County, Indiana, near the city of Salem. The mill was originally built in 1808, and rebuilt in 1864. For a brief time during the Civil War it was threatened with destruction, along with the other mills in Washington County, by John Hunt Morgan, the commanding general of a group of confederate soldiers known as Morgan’s Raiders, that passed through Kentucky, Indiana and Ohio between June 11 to July 26, 1863.
