On this date in 1876, the infamous James-Younger outlaw gang attempted to rob the First National Bank of Northfield, MN. When some of the local citizens saw what was going on, they armed themselves and confronted the gang. A gun battle ensued, leaving two townsfolk and a couple gang members dead. The remainder of the gang fled, and several were captured several days after the attempted robbery. Frank and Jesse James managed to escape, but the Northfield raid was the last hurrah for the James-Younger gang.
Every year, the city of Northfield holds a celebration called The Defeat of Jesse James Days.
