During the whole month of April the preparations for active war were going on with extreme vigor, and my letter-book shows an active correspondence with Generals Grant, Halleck, Thomas, McPherson, and Schofield on thousands of matters of detail and arrangement, most of which are embraced in my testimony before the Committee on the Conduct of the War, vol. i., Appendix.
When the time for action approached, viz., May 1,1864, the actual
armies prepared to move into Georgia resulted as follows, present
for battle:
Men.
Army of the Cumberland, Major-General THOMAS.
Infantry ………………….. 54,568
Artillery …………………. 2,377
Cavalry……………………. 3,828
Aggregate…………… 60,773
Number of field-guns, 130.
Army of the Tennessee, Major-General McPHERSON.
Infantry ………………….. 22,437
Artillery …………………. 1,404
Cavalry …………………… 624
Aggregate …………. 24,465
Guns, 96
Army of the Ohio, Major-General SCHOFIELD.
Infantry ………………….. 11,183
Artillery………………….. 679
Cavalry……………………. 1,697
Aggregate ………….. 13,559
Guns, 28.
Grand aggregate, 98,797 men and 254 guns
These figures do not embrace the cavalry divisions which were still incomplete, viz., of General Stoneman, at Lexington, Kentucky, and of General Garrard, at Columbia, Tennessee, who were then rapidly collecting horses, and joined us in the early stage of the campaign. General Stoneman, having a division of about four thousand men and horses, was attached to Schofield's Army of the Ohio. General Garrard's division, of about four thousand five hundred men and horses, was attached to General Thomas's command; and he had another irregular division of cavalry, commanded by Brigadier-General E. McCook. There was also a small brigade of cavalry, belonging to the Army of the Cumberland, attached temporarily to the Army of the Tennessee, which was commanded by Brigadier-General Judson Kilpatrick. These cavalry commands changed constantly in strength and numbers, and were generally used on the extreme flanks, or for some special detached service, as will be herein-after related. The Army of the Tennessee was still short by the two divisions detached with General Banks, up Red River, and two other divisions on furlough in Illinois, Indiana, and Ohio, but which were rendezvousing at Cairo, under Generals Leggett and Crocker, to form a part of the Seventeenth Corps, which corps was to be commanded by Major-General Frank P. Blair, then a member of Congress, in Washington. On the 2d of April I notified him by letter that I wanted him to join and to command these two divisions, which ought to be ready by the 1st of May. General Blair, with these two divisions, constituting the Seventeenth Army Corps, did not actually overtake us until we reached Acworth and Big Shanty, in Georgia, about the 9th of June, 1864.
In my letter of April 4th to General John A. Rawains, chief of staff to General Grant at Washington, I described at length all the preparations that were in progress for the active campaign thus contemplated, and therein estimated Schofield at twelve thousand, Thomas at forty-five thousand, and McPherson at thirty thousand. At first I intended to open the campaign about May 1st, by moving Schofield on Dalton from Cleveland, Thomas on the same objective from Chattanooga, and McPherson on Rome and Kingston from Gunter's Landing. My intention was merely to threaten Dalton in front, and to direct McPherson to act vigorously against the railroad below Resaca, far to the rear of the enemy. But by reason of his being short of his estimated strength by the four divisions before referred to, and thus being reduced to about twenty-four thousand men, I did not feel justified in placing him so far away from the support of the main body of the army, and therefore subsequently changed the plan of campaign, so far as to bring that army up to Chattanooga, and to direct it thence through Ship's Gap against the railroad to Johnston's rear, at or near Resaca, distant from Dalton only eighteen miles, and in full communication with the other armies by roads behind Rocky face Ridge, of about the same length.
On the 10th of April I received General Grant's letter of April 4th from Washington, which formed the basis of all the campaigns of the year 1864, and subsequently received another of April 19th, written from Culpepper, Virginia, both of which are now in my possession, in his own handwriting, and are here given entire. These letters embrace substantially all the orders he ever made on this particular subject, and these, it will be seen, devolved on me the details both as to the plan and execution of the campaign by the armies under my immediate command. These armies were to be directed against the rebel army commanded by General Joseph E. Johnston, then lying on the defensive, strongly intrenched at Dalton, Georgia; and I was required to follow it up closely and persistently, so that in no event could any part be detached to assist General Lee in Virginia; General Grant undertaking in like manner to keep Lee so busy that he could not respond to any calls of help by Johnston. Neither Atlanta, nor Augusta, nor Savannah, was the objective, but the "army of Jos. Johnston," go where it might.
