As the first Union regiment to volunteer for three years of service, the First Minnesota fought at the Battles of Bull Run, Antietam and Fredericksburg. It was, however, during the Battle of Gettysburg that the First Minnesota played a significant role in American military history. On the morning of July 2, 1863, the First Minnesota, along with the other units of the II Corps, took its position in the center of the Union line on Cemetery Ridge. Late in the day, the Union III Corps, under heavy attack by the Confederate I Corps, collapsed creating a dangerous gap in the Union line. The advancing Confederate brigades were in position to breakthrough and then envelope the Union forces. At that critical moment, the First Minnesota was ordered to attack. With leveled bayonets and at maximum forward speed, 262 Minnesotans attack Wilcox's 1,600 Alabamians on July 2, 1863, at Gettysburg. Original painting by Don Troiani.
