The Tennessee Maneuver Area was a training area in Middle Tennessee, comprising the following counties: Bedford, Cannon, Clay, Coffee, Davidson, DeKalb, Franklin, Giles, Jackson, Lincoln, Macon, Marshall, Maury, Moore, Putnam, Robertson, Rutherford, Smith, Sumner, Trousdale, Warren, White, Williamson, and Wilson. The area was selected because the terrain resembled France, Belgium and Germany.
In June 1941, Major General George S. Patton conducted maneuvers with the 2nd Armored Division in the Manchester, Tennessee vicinity, where he soundly defeated the opposing forces, proving large-scale armored fighting based on Bedford Forrest’s cavalry doctrine. As a result of these maneuvers lead to the creation of the Tennessee Maneuver Area.
