The bill establishes July 2 as "1st Minnesota Day" to honor the 262 men of the 1st Minnesota Regiment who fought valiantly during the Civil War on that date in 1863. The legislation highlights the significance of their charge, which resulted in the loss of 215 men but ultimately contributed to the Union's success in the battle. The bill mandates that the governor issue a proclamation each year to commemorate this observance and encourages schools to educate students about the regiment's role in the Civil War, emphasizing the stories of those who fought for freedom and democracy.

Additionally, the bill requires that on July 2 each year, the commissioner of administration, in collaboration with the Minnesota Historical Society, fly a replica of the 1st Minnesota Regimental flag on the North flag pole of the Minnesota State Capitol, replacing the POW/MIA flag for that day. This section of the bill will take effect the day after it is enacted.
