Around 3:00 p.m., Colonel Harrison arrived with Confederate reinforcements, and General Colquitt ordered the troops to advance. Colonel Barton's brigade on the north was soon subjected to concentrated fire in the area recently vacated by the 7th New Hampshire. The continuous roar of battle lasted another three hours without a pause as grape and canister swept through the fighting, shells tore through the ranks, and the 115th New York swept forward through reeds, over logs and fences, until the southern gray columns were plainly visible. Confederate forces advanced about two hundred yards before meeting stubborn resistance again.
