 While riding with his infantry in a wide berth well south and west of the Federal line of battle, Jackson employed Maj. Gen. Fitzhugh Lee's cavalry to provide for better reconnaissance regarding the exact location of the Union right and rear.The results were far better than even Jackson could have hoped.Fitzhugh Lee found the entire right side of the Federal lines in the middle of open field, guarded merely by two guns that faced westward, as well as the supplies and rear encampments.
