The 11th Indiana Infantry Regiment, also known as the Indiana Zouaves, under the command of Lew Wallace, was the first regiment organized in Indiana during the Civil War and the first one to march into battle. The 11th Indiana fought in the Battle of Fort Donelson, the Siege of Vicksburg, the second day of the Battle of Shiloh, and elsewhere. In 1861 the 9th Indiana Infantry Regiment became one of the first Hoosier regiments to see action in the war. The 9th Indiana fought in many major battles, including the Battle of Shiloh, the Battle of Stones River, the Atlanta Campaign, and the Battle of Nashville, among others.
