When the cavalry could not break the Union flank on its own, Early sent Maj. Gen. John B. Gordon's infantry division across the ford to assist in the attack. Gordon launched a three-pronged attack with three brigades against Ricketts's center and both flanks. Ricketts's right flank was pushed back, allowing the Confederates to enfilade the Union line. Pressure from Ramseur's attack on the Union center and Confederate artillery fire from across the river kept Wallace from reinforcing Ricketts's men. Unable to hold the Union line, Wallace ordered a retreat towards Baltimore, leaving Tyler's brigade holding the stone bridge with a small force of men. Clendenin's cavalry remained south on the Georgetown Pike as a rearguard. Rodes's Confederate troops made one final push to capture the stone bridge about 6 p.m., but most of the Union troops were already headed toward Baltimore. At the end of the day, the outnumbered Union forces had withstood five attacks before they were forced to retreat.
