As early as 1825, the majority of the population were against slavery. By the time of the War, Jasper County was one of the few counties of Indiana that had a military organization under the law of 1855. The war greatly affected Jasper County when 935 soldiers were enlisted on behalf of the Union. This was considered an impressive amount at the time with the average population around 5,000. Although there were several companies from Indiana, the 9th Indiana Infantry Regiment produced Robert H. Milroy, the Gray Eagle of the Army. Milroy became famous for suppressing Confederate mountain rangers, which caused the Confederate Congress to declare a $100,000 bounty on his head. The 9th Indiana Infantry Regiment became known for its involvement in the Battle of Philippi, one of the earliest battles of the Civil War at Laurel Hill (now known as Laurel Mountain). In comparing the proportions of men able to fight, Indiana contributed more soldiers than any other state to the Union.
