American Civil War Military Units

During the American Civil War, essentially four basic types of military units fought in the conflict. These units consisted of cavalry units, infantry units, artillery units, and men on naval vessels. Ohioans served in all four types of units, providing the federal government with more than 260 different regiments of men among these four types of military units. During the war’s course, the federal government requested that the State of Ohio provide the Union military with 306,322 men to reunite the country. Ohio exceeded that number by 4,332 men, providing 310,654 men officially. In reality, Ohio provided even more men, as numerous men served in military units from other states, especially ones in West Virginia and Kentucky. In addition to these men, 5,092 Ohio African Americans enlisted in the United States Colored Troops or in units from other states, most notably in Massachusetts, where Ohio blacks principally joined the 54^th and 55^th Massachusetts Infantry Regiments. An additional 6,479 men paid a fine to be excluded from military service, making Ohio’s contribution to the Union war effort closer to 330,000 men.
