Indiana Civil War Camps
Indiana is a state that is usually over looked with its involvement in the Civil War. The Hoosier State was a major supplier of troops and it housed a large majority of Confederate prisoners of war. Civil War camps in Indiana were training camps, prison camps or both. When a camp was used solely as a training camp, it usually was only in operation for a few months while regiments were being trained there. Training camps were often turned into prison camps. Camp Morton is a good example of how camps evolved in the Union. Camp Morton started as a training camp and then it was converted into a prison camp. Camp Morton became the central hub for the other prison camps in the area. The prison camp made a major impact during the Civil War because of the amount of Confederate soldiers imprisoned there. The other prison camps in the area usually held prisoners only if Camp Morton was over filled; which was a very common occurrence because it was usually over crowded.
Camp Morton was a recruiting camp, prison camp for Confederate soldiers, and a place of detention for Union soldiers. Camp Morton was created when Governor Oliver Morton asked for 12,000 men to come forward to fight. The Governor needed somewhere for these troops to train. Camp Morton is located where the State Fair Grounds use to be until 1892; today this location is residential property. Camp Morton was originally intended solely to be a training camp but after the Battle of Shiloh, it became one of the Union's most important prison camps. The majority of Confederate troops captured in Kentucky and Tennessee went to Camp Morton. During Morgan's Raid, Morgan considered moving up toward Indianapolis to release the imprisoned Confederate soldiers but ultimately he decided to head toward Ohio. Ironically, all of Morgan's troops captured during the raid were taken to Camp Morton. Camp Morton was known for the poor living conditions of the inmates. It was said that the prisoners at Camp Morton were walking skeletons, who were lucky to eat once a day. They were poorly cared for. Inadequate clothes, terrible sanitary facilities and close personal contact contributed to the inmates' short life expectancy in the prison camp. Many inmates died from diseases they incurred in the camp.
