Gettysburg is considered the most famous Civil War battle and a crucial turning point for Union forces. On the morning of July 1, the 2nd Wisconsin Infantry was the first to engage with Confederate troops. It immediately lost nearly one-third of its men. Among them was Colonel Lucius Fairchild, whose left arm had to be amputated. The Iron Brigade (including the 2nd, 6th, 7th Wisconsin Infantry regiments), the 3rd, 5th, and 26th Wisconsin Infantry regiments, and the 1st U.S. Sharpshooters, Company G (Berdan’s Sharpshooters) fought at Gettysburg.
