Civil War ravishes the nation.
Meigs County is on the borderline between the North and South. Morgan's Raiders are defeated by Meigs County militia, and Union forces led by Brigadier General Henry M. Judah, and Edward H. Hobson. At least two former U.S. Presidents participated in this battle, if not possibly three. They were Rutherford Hayes, William McKinley, and possibly James Garfield, interestingly enough all born in Ohio. Meigs County was also part of the Underground Railroad, that transported slaves to freedom.
