whole engagement. It is the more creditable, because the death of a commanding officer would naturally tend to weaken confidence and diminish courage.

Captain J. B. Weller was wounded at the time Lieutenant-Colonel Coleman was killed, which left his company without a commissioned officer. Companies A, E, and were without officers, and yet the men did their duty well.

I have the honor to be, your most obedient servant,

LYMAN J. JACKSON,

Major, Commanding Eleventh Regiment Ohio Volunteer Infantry.
