On September 14, the battle took place on three gaps. A few Confederate regiments guarded the two northern gaps, Turner's and Fox's and Crampton's Gap to the south. The Union army advanced from the east and attacked in two waves. The first wave attacked Fox's Gap at about 9 am. Early in the afternoon the second wave hit both Fox's and Turner's Gaps at the same time. Crampton's Gap was attacked in the late afternoon.
