Twenty-four guns of the 3rd New York Artillery supported Gen. Wessells’ infantry as they advanced through the swamp toward the Confederate line. The overwhelming firepower of Union infantry and artillery eventually forced the Confederates to abandon the line and fall back to Jones Bridge. When Wessells gave the order to attack, two guns of Battery B came forward and opened fire. The battery’s remaining four guns soon joined them, all firing at the Confederate line near Harriet’s Chapel. Col. James H. Ledie, chief of the Union artillery, then brought batteries E, F and I—eighteen guns—into action. Lt. H.F. Scaife wrote that the battery they were supporting was ripping up the woods in fine style, at every discharge cracking off pine trees as if they had been pipe stems. As the battle progressed, Col. Ledie moved Battery F to the extreme right of the Union line in support of infantry near the Confederate earthworks. A South Carolina officer recalled that the firing in the front was incessant and that balls and shells from the Federal guns were falling about the bridge. The Confederates abandoned their position.
