This view is taken from about 3/4 of the way to the top of the Confederate high ground on the west side of the creek. From here, behind stone fences and along pre-battle trenches dug as a quarry operation, the Confederates dominated the field. After hurling back the 11th Connecticut and two waves of attacks from Nagle's Brigade, the Confederates ran low on ammunition when Ferrero's attack commenced. Ferrero's troops took up position along fences along the opposit side of the bridge; the slackening of Confederate fire eventually drew them onto and across the brigde itself. Once Union troops were across the bridge, the Confederates put up no resistance and fled the area. Now on the west side of the creek, McClellan had the opportunity to hit Lee's right flank hard. And, although there was some rough hilly terrain ahead, there was little in terms of Confederate troops to stop a Union drive toward Sharpsburg.
