1863 – (Civil War) Battle of Chickamauga, Georgia

The defeat at Chickamauga, Georgia, left Union troops pinned inside Chattanooga, Tennessee, and temporarily halted their advance into the heart of the Confederacy. Nine Wisconsin regiments participated. The chaplain of the 1st Wisconsin Infantry reported that 80 percent of its men were killed, wounded, or taken prisoner. The 15th Wisconsin Infantry, composed almost entirely of Norwegian immigrants, was led on the field by Colonel Hans C. Heg, who was killed in action.
