After his graduation* [from West Point] he returned home, and occupied himself in the peaceful life of a farmer. When President Lincoln issued his call for seventy-five thousand men, A. H. Colemnn responded, and in forty-eight hours he raised Company D, Eleventh Ohio Volunteer Infantry, and went with them to Columbus, Ohio, where he was unanimously chosen captain of the company ..."(from Miami History)
He was enrolled 25 April 1861 in the 11th Ohio Infantry for 3 months service, and appointed Major on 29 April. He was discharged to accept appointment as Major of the 11th Infantry for 3 years service on 7 July 1861. He was promoted to Lieutenant Colonel on 9 January 1862. He was appointed Colonel on 23 April, but not mustered at that rank.
On the Campaign
"and I cannot refrain from paying the poor tribute of honorable mention to the memory of Lieutenant-Colonel Coleman, commanding Eleventh Regiment Ohio Volunteer Infantry. He had acted the part of a hero at the recent fight at Bull Run Bridge and at the battle of South Mountain. He met a hero's death in the battle of the 17th of September."
(from Col Scammon's report)

* This statement may not be completely true. The USMA Archives [formerly online, gone as of 2/2002] Official Register for 1849 (end of his second year) indicates he was 'deficient' and sent back to repeat the year. He repeated that year, and was successful. He then failed the next, his third year (ending June 1851), and is not found in the Register for 1852 - suggesting he did not continue at the Academy.
