Ohio had the highest percentage of population enlisted in the military of any state. Sixty percent of all the men between the ages of 18 and 45 were in the service. Ohio mustered 230 regiments of infantry and cavalry, as well as 25 light artillery batteries and 5 independent companies of sharpshooters.
