Lieutenant Colonel Baker was then promoted to colonel and continued to lead the 2nd Iowa Infantry. Noah W. Mills was promoted from captain of Company D to lieutenant colonel. James B. Weaver was third in command as major from Company G. During the fighting at Shiloh, the 2nd Iowa again proved themselves as brave and vital to the Federal forces, and seven of the men sacrificed their lives and an additional thirty seven were wounded. Iuka-Corinth Campaign The 2nd Iowa Infantry would remain at Pittsburg Landing until April 28, 1862. From there, the 2nd Iowa assisted in the advance on Corinth by General Halleck. The men constantly expected battle with Confederate General Beauregard and his army as the Federal forces under Halleck slowly made their way to Corinth, but Beauregard never confronted the Federal forces. After General Halleck created a line directly in front of Corinth, Beauregard and his army evacuated the city. The 2nd Iowa participated in the advance on Corinth for thirty days. On May 30, 1862, General Halleck's army marched into the evacuated Corinth uncontested. The 2nd Iowa participated in the unsuccessful chase after General Beauregard before reporting back to Camp Montgomery, located near Corinth, on June 15. The 2nd Iowa remained near Corinth for the remainder of the summer; remaining in General Grant's Army of the Tennessee. During the summer, the 2nd Iowa was assigned chiefly to camp and picket-duty. The majority of the Confederate forces were near Chattanooga, Tennessee, and the city of Corinth was in no immediate danger. The situation would not change until early September when Confederate General Sterling Price advanced his troops to the city of Iuka, just twenty miles east from Corinth. Federal Generals William Rosecrans and Edward Ord, each commanding two divisions, met General Price's force at Iuka. After a fierce fight which cost Price approximately 500 casualties, he turned away and regrouped with General Earl Van Dorn, creating a Confederate force of approximately 40,000 men ready to attack Corinth. The attack would come on October 3, and the 2nd Iowa Infantry would fight for two days in one of the most strategically important battles in the Civil War. During the early morning of October 3, the 2nd Iowa, being a part of the First Brigade of the Second Division of the Army of the Tennessee under Brigadier General Thomas A. Davies, moved their line of defense two miles ahead
