the
supply and ammunition trains of the division all surplus
transportation, and restricting the personal baggage of officers to
the fewest effects possible.

My own staff also was somewhat reorganized and increased at Mill
Creek, and though it had been perfectly satisfactory before, yet, on
account of the changes of troops that had occurred in the command, I
found it necessary to replace valuable officers in some instances,
and secure additional ones in others. The gathering of information
about the enemy was also industriously pursued, and Card and his
brothers were used constantly on expeditions within the Confederate
lines, frequently visiting Murfreesboro', Sparta, Tullahoma,
Shelbyville, and other points. What they learned was reported to
army headquarters, often orally through me or personally communicated
by Card himself, but much was forwarded in official letters,
beginning with November 24, when I transmitted accurate information
of the concentration of Bragg's main force at Tullahoma. Indeed,
Card kept me so well posted as to every movement of the enemy, not
only with reference to the troops in my immediate front, but also
throughout his whole army, that General Rosecrans placed the most
unreserved reliance on all his statements, and many times used them
to check and correct the reports brought in by his own scouts.

Slight skirmishes took place frequently during this period, and now
and then heavy demonstrations were made in the neighborhood of
Nolensville by reconnoitring parties from both armies, but none of
these ever grew into a battle. These affairs sprung from the desire
of each side to feel his antagonist, and had little result beyond
emphasizing the fact that behind each line of pickets lay a massed
and powerful army busily preparing for the inevitable conflict and
eager for its opening. So it wore on till the evening of December
25, 1862; then came the order to move forward.

General Rosecrans, in the reorganization of the army, had assigned
Major-General A. McD. McCook to command the right wing, Major-General
George H. Thomas the centre, and Major-General T. L. Crittenden the
left wing. McCook's wing was made up of three divisions, commanded
in order of rank by Brigadier-General Jeff. C. Davis;
Brigadier-General R. W. Johnson, and Brigadier-General P. H. Sheridan.
Although the corps nomenclature established by General Buell was
dropped, the grand divisions into which he had organized the
