H = Howitzer

N = Napoleons

WR = Wiard Rifles

PR = Parrott Rifles

RR = Rodman Rifles

Leader status listings, in red are used in the following way:

w = Wounded

w-mortally = Mortally wounded

k = Killed

c = Captured

d = Disabled

t = Temporarily commanding

Note:

On all of the OOB’s which I have seen dealing with the Army of the Ohio, the total manpower is listed as 17,918 men. I come up with a total of 20,397 men. Several of this Armies units did not make it to the battlefield on time, so the 17,918 manpower figure for men engaged is probably close.
