On July 2, 1863, the Battle of Hunterstown took place about five miles northeast of Gettysburg. Gen. Wade Hampton's cavalry brigade was sent to protect the Confederate left flank where they were met by Gen. George Custer's cavalry. Custer was unhorsed in the ensuing melee, pinned by his horse, and saved by Norvell Churchill, an orderly.
