After the outer works fell, General Wilson himself led the 4th U.S. Cavalry Regiment in a mounted charge down the Range Line Road toward the unfinished inner line of works. The retreating Confederate forces, upon reaching the inner works, all rallied and poured a devastating fire into the charging column. This broke up the charge and sent General Wilson sprawling to the ground when his favorite horse was wounded. He quickly remounted his stricken mount and ordered a dismounted assault by several regiments.
