Richard S. Ewell
Kilpatrick's division, which was reinforced with cavalry stationed at Emmitsburg, Maryland, pursued Lee's retreating army. Late at night high in the mountains, near Monterey Pass, a dismounted advance guard company from Custer's 2nd Brigade confronted a small group of rebels guarding the pass. The rebels, using only one piece of artillery, prevented Custer's men from entering the pass while a wagon train belonging to Confederate General Richard S. Ewell moved from the north into the pass.
