The 3rd Wisconsin Infantry Regiment played a significant role in the American Civil War, earning a reputation for resilience and dedication. Mustered into service on June 29, 1861, the regiment was composed of volunteers from across Wisconsin, united by a shared sense of duty and patriotism. The 3rd Wisconsin first saw action in the Shenandoah Valley, where it participated in pivotal campaigns against Confederate forces under the command of Stonewall Jackson. The regiment’s discipline and courage were tested in numerous engagements, including the Battles of Antietam and Chancellorsville, where they faced fierce opposition but remained steadfast. Perhaps most notably, the 3rd Wisconsin Infantry fought valiantly at the Battle of Gettysburg, contributing to the Union victory that turned the tide of the war. At the start of 1864, a majority of the regiment re-enlisted, demonstrating their unwavering commitment to the cause. They subsequently served under General William Tecumseh Sherman during his famous “March to the Sea,” further solidifying their legacy as a formidable force in the Union Army. Their service extended beyond the battlefield, as they also played a critical role in guarding supply lines and maintaining order in occupied territories. By the end of their service in July 1865, the men of the 3rd Wisconsin Infantry had participated in over 30 battles and skirmishes. Their sacrifices and unwavering commitment to the Union cause left an enduring legacy, commemorated in Wisconsin’s history.
