a soldier on railroad duty still risked his life daily. For example, in mid-July, Company A skirmished with the Confederates near the Charriton railroad bridge. While guarding this bridge, a small group of soldiers discovered Confederate bridge burners. After engaging the rebels, who were estimated as numbered between 80 and 100 men, Company A managed to save the bridge, capture five horses, and kill 18 Confederate soldiers. After St. Joseph, the 2nd Iowa embarked on the journey across Missouri to Bird's Point, Missouri, and the surrounding area for similar duties. The regiment arrived at Bird's Point on August 2, 1861, and performed more guarding duties similar to those in St. Joseph. Soon after, the regiment marched to Jackson and Pilot Knob, Missouri, and Fort Jefferson, Kentucky, for more guarding duty until reporting back to Bird's Point on September 24, 1861. After arriving at Bird's Point for the second time, the 2nd Iowa remained there from the end of September to the end of October 1861. Colonel Curtis was promoted to brigadier general and Lt. Colonel Tuttle became the new leader of the regiment, receiving his promotion to colonel on September 6, 1861. While serving at Bird's Point and the surrounding area, the 2nd Iowa lived in poor conditions, which caused much illness. An estimated 400 of 1000 men were able to serve. Because of the poor state of health, the 2nd Iowa was ordered to the Benton Barracks in St. Louis, Missouri, in order to recuperate and recruit in order to replace the men who had died from disease. The 2nd Iowa arrived in St. Louis on October 29, and by December 26 the regiment's sick list numbered about 200. As the overall health of the regiment continued to improve, the 2nd Iowa was ordered to guard McDowell College. After the owner of the college joined the Confederate army, the U.S. War Department seized the school and converted it into a military prison. When the 2nd Iowa began guarding the prison, there were approximately 1,300 prisoners held at the college. Thanks to some reeducation and the resulting oaths of allegiance, the number was reduced to approximately 1,100 prisoners at the time of the 2nd Iowa's departure. Colonel Tuttle led the re-education of the prisoners, teaching the rebels “Uncle Samuel is not to be fooled with and that [the prisoners] have to submit or somebody will get hurt.” Shortly before the
