the Battle of Pea Ridge, in which Dodge commanded a brigade, and the Fourth Regiment was under command of Lieutenant-Colonel Galligan, who was wounded in the battle and resigned, April 3d, when Adjutant J. A. Williamson was promoted to lieutenant-colonel, and Lieutenant R. A. Stitt became adjutant. The Fourth was in the thickest of the fight at Pea Ridge on both days, and did excellent service, losing nearly one-half of its entire number in killed, wounded and missing. Dodge and Williamson were among the wounded. In the first day’s battle, on the 7th of March, 1862, the Fourth Iowa, in the brigade commanded by Colonel Dodge, fought like veterans. Early in the day, General Carr’s Division, on the right wing of Curtis’ army, assailed by overwhelming numbers, made a most determined fight. For seven hours the Rebels pressed on his lines, and his division was forced back half a mile, while presenting an unbroken front to the enemy. The Fourth Iowa and Thirty-fifth Illinois, under Dodge, lying behind an old fence, were now attacked by a greatly superior force supported by artillery. The charge was met by a deadly fire and the enemy driven back in confusion. Again and again the Rebels rallied and renewed the attack and were each time repulsed with heavy loss. At one time the ammunition became exhausted and the Fourth made a gallant bayonet charge under the direction of General Curtis. The splendid fighting of the Fourth Iowa and Thirty-fifth Illinois challenged the admiration of General Van Dorn and other Confederate officers. For brilliant services in this battle, Colonel Dodge was made a Brigadier-General; Williamson was promoted to colonel; Captain Burton to lieutenant-colonel.
Having driven the Confederate army out of Missouri, General Curtis marched toward Little Rock. The continuous rains rendered the roads nearly impassable and after remaining at Batesville and Jacksonsport several months, and finding it impossible to subsist his army in the country, he marched to Helena.
