The engagement at Jackson occurred during
Confederate Brig. Gen. Nathan Bedford Forrest's
Expedition into West Tennessee, between December 11, 1862, and January 1, 1863. Forrest wished to interrupt the rail supply line to
Maj. Gen. Ulysses S. Grant's army, campaigning down the Mississippi Central Railroad. If he could destroy the Mobile & Ohio Railroad running south from
Columbus, Kentucky, through
Jackson, Tennessee, Grant would have to curtail or halt his operations. Forrest's 2,100-man cavalry brigade crossed the
Tennessee River from December 15 to December 17, heading west. Grant ordered a troop concentration at Jackson under Brig. Gen.
Jeremiah C. Sullivan and sent a cavalry force out under Col.
Robert G. Ingersoll, to confront Forrest. Forrest, however, smashed the Union cavalry
at Lexington on December 18. ==Battle==
