The Battle of Johnsonville was fought November 4–5, 1864, in Benton County, Tennessee and Humphreys County, Tennessee, during the American Civil War. Confederate cavalry commander Major General Nathan Bedford Forrest culminated a 23-day raid through western Tennessee by attacking the Union supply base at Johnsonville. Forrest's attack destroyed numerous boats in the Tennessee River and millions of dollars of supplies, disrupting the logistical operations of Union Major General George H. Thomas in Nashville.
