As ordered, the 2nd Iowa marched in silence, without firing a shot. The regiment marched in line over the open meadow, through a gully, over a rail fence, and up a hill cluttered with broken trees when suddenly the enemy came into sight and a steady rain of lead poured into the ranks of the brave men. The 2nd Iowa answered with a deafening roar and continued to advance toward the Confederates despite their losses. The march was challenging and costly as volley after volley leveled the men of the 2nd Iowa Infantry. Continuing to absorb the damage from the enemy, the 2nd Iowa marched across the difficult terrain. Colonel Tuttle and Lieutenant Colonel Baker were both injured in the charge, yet they remained on the field throughout the charge. Company captains Jonathon Slaymaker and Charles Cloutman were killed in the charge. When Captain Slaymaker fell and his men tried to help him, he yelled, “Go on! Go on! Don’t stop for me!” At least five members of the color guard were wounded or killed before Corporal Voltaire Twombly would take the flag and be hit in the chest by a spent ball. However, he would rise again and charge with the colors until the day was done. Twombly would be awarded the Medal of Honor for his actions. Acts of bravery like those mentioned were normal for the men of the 2nd Iowa during the charge. Despite running for 200 yards under enemy fire, the 2nd Iowa would successfully charge and cross into the enemies works without firing a single round from their muskets. Once inside the enemy breastworks, the men of the 2nd Iowa opened fire on the Confederate soldiers, most of whom fell back to the next trench. Those who refused to retreat were put down by the men's bayonet. The men of the 2nd Iowa continued their attack on the Confederate forces and followed them into the next line of trenches before the Confederates could regroup and counterattack. At this point in the battle, the rest of the brigade, which formed the right wing of attack, began occupying the first trench and firing upon the second entrenchment. Friendly fire from the 52nd Indiana Infantry caused more casualties for the 2nd Iowa. In the confusion, the 2nd Iowa fell back into the first entrenchment and regrouped with their comrades behind them. General Smith then ordered the regiment to take cover behind the walls of the first trench while the 25th Indiana unsuccessfully tried to take the second trench by bayonet.
