Franklin Steele formally takes possession of the Fort Snelling military reservation, which he had bought from the government for $90,000. Although Steele envisioned a city on the grounds of the fort, this idea failed and Steele was unable to keep up the payments. During the Civil War the government reasserted its claim to the fort, which would remain in government hands until after World War II.

Sergeant Louis Cukela, a Croatian-born Minneapolitan serving in France, performs a feat of heroism that earns him two Congressional Medals of Honor, one from the navy and one from the army. Cukela, a member of the Fifth Marine Regiment, was pinned down with his company by machine-gun fire. Cukela worked his way around the side of the emplacement and used his bayonet to kill or capture members of the crew. He then threw a grenade into another machine gun nest, capturing it as well. A number of Minnesotans have won the nation's highest honor for bravery, but only Cukela has won two.

Modifying the territorial seal, the design includes the slogan L'Etoile du Nord (Star of the North) and depicts a white man plowing eastward and looking over his shoulder at a Native American man on horseback riding toward the setting sun. Minor changes have been made to the seal since then, including the addition of Norway pines in the background and a shift of the Native man's route so that he rides toward the south.

While charting the Mississippi River for the US Army on the site of present-day St. Paul, Major Stephen H. Long comes across a cavern known to local Dakota people as Inyan Tipi (settler-colonists came to call it Fountain Cave).
