The Stone Bridge over Bull Run was the left flank of the Confederate line. Col. "Shank" Evans and his two regiments were positioned above this bridge overlooking this crossing. A signal officer noticed the Federal column moving and sent word to Col. Evans "Look to your left, you are being turned!"

Col. Evans left two hundred troops to defend the Stone Bridge and moved with nine hundred troops to Matthews Hill to block the flanking column of Federal troops. The small force held for thirty minutes as soldiers from Burnside's and Porter's brigades entered the battle. Four regiments under General Bee and General Bartow reinforced Col. Evans and moved to Evan's right. The line of cannon indicates the position of the Federal line.

The Federal troops outnumbered the Confederate soldiers by ten thousand men and both Confederate flanks were being overlapped. The Confederates retreated to Henry Hill. This photograph was Evans right line on Matthews Hill. At the marker, Stovall of Georgia was killed while moving his wounded brother to safety.
