On my arrival at St. Louis I felt somewhat forlorn and disheartened at the turn affairs had taken. I did not know where I should be assigned, nor what I should be required to do, but these uncertainties were dispelled in a few days by General Halleck, who, being much pressed by the Governors of some of the Western States to disburse money in their sections, sent me out into the Northwest with a sort of roving commission to purchase horses for the use of the army. I went to Madison and Racine, Wis., at which places I bought two hundred horses, which were shipped to St. Louis. At Chicago I bought two hundred more, and as the prices paid at the latter point showed that Illinois was the cheapest market—it at that time producing a surplus over home demands—I determined to make Chicago the centre of my operations.
While occupied in this way at Chicago the battle of Shiloh took place, and the desire for active service with troops became uppermost in my thoughts, so I returned to St. Louis to see if I could not get into the field. General Halleck having gone down to the Shiloh battle-field, I reported to his Assistant Adjutant-General, Colonel John C. Kelton, and told him of my anxiety to take a hand in active field-service, adding that I did not wish to join my regiment, which was still organizing and recruiting at Jefferson Barracks, for I felt confident I could be more useful elsewhere. Kelton knew that the purchasing duty was but temporary, and that on its completion, probably at no distant date, I should have to join my company at the barracks; so, realizing the inactivity to which that situation of affairs would subject me, he decided to assume the responsibility of sending me to report to General Halleck at Shiloh, and gave me an order to that effect.
This I consider the turning-point in my military career, and shall always feel grateful to Colonel Kelton for his kindly act which so greatly influenced my future. My desire to join the army at Shiloh had now taken possession of me, and I was bent on getting there by the first means available. Learning that a hospital-boat under charge of Dr. Hough was preparing to start for Pittsburg Landing, I obtained the Doctor's consent to take passage on it, and on the evening of April 15, I left St. Louis for the scene of military operations in northeastern Mississippi.
At Pittsburg Landing I reported to General Halleck, who, after some slight delay, assigned me to duty as an assistant to Colonel George Thom, of the topographical engineers. Colonel Thom put me at the work of getting the trains up from the landing, which involved the repair of roads for that purpose by corduroying the marshy places. This was rough, hard work, without much chance of reward, but it, was near the field of active operations, and I determined to do the best I could at it till opportunity for something better might arise.
General Halleck did not know much about taking care of himself in the field. His camp arrangements were wholly inadequate, and in consequence he and all the officers about him were subjected to much unnecessary discomfort and annoyance. Someone suggested to him to appoint me quartermaster for his headquarters, with a view to systematizing the establishment and remedying the defects complained of, and I was consequently assigned to this duty. Shortly after this assignment I had the satisfaction of knowing that General Halleck was delighted with the improvements made at headquarters, both in camp outfit and transportation, and in administration generally. My popularity grew as the improvements increased, but one trifling incident came near marring it. There was some hitch about getting fresh beef for General Halleck's mess, and as by this time everybody had come to look to me for anything and everything in the way of comfort, Colonel Joe McKibben brought an order from the General for me to get fresh beef for the headquarters mess. I was not caterer for this mess, nor did I belong to it even, so I refused point-blank. McKibben, disliking to report my disobedience, undertook persuasion, and brought Colonel Thom to see me to aid in his negotiations, but I would not give in, so McKibben in the kindness of his heart rode several miles in order to procure the beef himself, and thus save me from the dire results which be thought would follow should Halleck get wind of such downright insubordination. The next day I was made Commissary of Subsistence for the headquarters in addition to my other duties, and as this brought me into the line of fresh beef, General Halleck had no cause thereafter to complain of a scarcity of that article in his mess.
My stay at General Halleck's headquarters was exceedingly agreeable, and my personal intercourse with officers on duty there was not only pleasant and instructive, but offered opportunities for improvement and advancement for which hardly any other post could have afforded like chances. My special duties did not occupy all my time, and whenever possible I used to go over to General Sherman's division, which held the extreme right of our line in the advance on Corinth, to witness the little engagements occurring there continuously during the slow progress which the army was then making, the enemy being forced back but a short distance each day. I knew General Sherman very well. We came from near the same section of country in Ohio, and his wife and her family had known me from childhood. I was always kindly received by the General, and one day he asked me if I would be willing to accept the colonelcy of a certain Ohio regiment if he secured the appointment. I gladly told him yes, if General Halleck would let me go; but I was doomed to disappointment, for in about a week or so afterward General Sherman informed me that the Governor of Ohio would not consent, having already decided to appoint some one else.
A little later Governor Blair, of Michigan, who was with the army temporarily in the interest of the troops from his State, and who just at this time was looking around for a colonel for the Second Michigan Cavalry, and very anxious to get a regular officer, fixed upon me as the man. The regiment was then somewhat run down by losses from sickness, and considerably split into factions growing out of jealousies engendered by local differences previous to organization, and the Governor desired to bridge over all these troubles by giving the regiment a commander who knew nothing about them. I presume that some one said to the Governor about this time, "Why don't you get Sheridan?" This, however, is only conjecture. I really do not know how my name was proposed to him, but I have often been told since that General Gordon Granger, whom I knew slightly then, and who had been the former colonel of the regiment, first suggested the
