Colonel Carrington was ordered to proceed with this detachment to, Louisville, Ky., and there report to General Buell, who was then engaged in organizing the Army of the Ohio. Colonel Carrington accordingly left Camp Thomas December 2, 1861, the 1st Battalion under Major Underwood, the 2d under Major Townsend.
On the 16th of the same month, at Lebanon, Ky., Colonel Carrington turned over the command to Lieutenant-Colonel Shepherd, and returned to Camp Thomas to complete the organization of the regiment.
*Under the direction of Colonel H. M. Lazelle, 18th U. S. Infantry.
General Buell assigned the i8th Infantry to the 3d Brigade, 1st Division, Army of the Ohio, General George H. Thomas being the division commander. The history of the 18th Infantry during the four momentous years of the Rebellion is so intimately connected with that of General Thomas, that to follow it intelligently, one is compelled to make a study of his campaigns.
The 18th Infantry formed apart of the force under that general which, in December, 1861, and part of February, 1862, operated against the Confederate forces under Generals A. S. Johnston and George Crittenden, in southwestern Kentucky. Owing to the condition of the roads, the 18th Infantry did not reach the field in time to participate in the battle of Mill Springs, Ky., January 18, 1862.
A. S. Johnston having retired into Tennessee, General Thomas was ordered with his division to proceed by forced marches to Louisville, and thence to embark for Nashville, Tenn. The 18th Infantry reached Nashville March 3, 1862. On the 6th of March Major W. A. Stokes, 18th Infantry, with companies A, B and E, 3d Battalion, and G, 1st Battalion, joined the first detachment of the regiment, but Major Stokes' appointment was not confirmed by the Senate and the 3d Battalion was discontinued, the companies composing it being temporarily attached to the 1st and 2d Battalions.
The regiment, as a part of the 1st Division, Army of the Ohio marched from Nashville, March 20, to participate in the operations against the enemy's position at Corinth�Savannah on the Tennessee River, being the point to which its march was directed. During this march the officers and men suffered great hardships. The roads were knee-deep with mud, the weather was stormy, rations were short, shelter could not be obtained at night, and the wagon trains were delayed many days. The command did not reach Savannah until April 8, and was transferred the next day by steamboat to Pittsburg Landing.
On the 24th of April the regiment had its first engagement with the enemy. Having moved camp beyond Shiloh Creek, it was sent on reconnoissance, and drove back the enemy's outposts beyond Lick Creek and Pea Ridge, capturing some prisoners. The commanding general having determined upon the reduction of the enemy's position at Corinth, Miss., the combined Armies of the Ohio, Tennessee and Mississippi, were reorganized and the 18th Infantry passed from the 1st Division, Army of...
