Ohio and Michigan went to war over a strip of land, and nobody died

In 1835–36, Ohio and the Michigan Territory both claimed the 'Toledo Strip', each sending armed militia to enforce its own courts there. Musket volleys were fired, but the only reported casualty was a sheriff's deputy stabbed with a penknife. Congress settled it by giving Toledo to Ohio and compensating Michigan with the vast, then-worthless Upper Peninsula — later found to hold rich copper and iron deposits.
