 Cemeteries throughout the South contain the remains of Iowa soldiers who fell during the war, with the largest concentration at Vicksburg National Cemetery.A number also died in Confederate prison camps, including Andersonville prison.Though the total number of Iowans who served in the military during the Civil War seems small compared to the more heavily populated eastern and southern states, no other state, north or south, had a higher percentage of its male population between the ages of 15 and 40 serve in the military during the course of the war.
