These five corps were very much reduced in strength, by detachments and by discharges, so that for the purpose of fighting Hood I had only about sixty thousand infantry and artillery, with two small divisions of cavalry (Kilpatrick’s and Garrard’s).  General Elliott was the chief of cavalry to the Army of the Cumberland, and was the senior officer of that arm of service present for duty with me.

We had strong railroad guards at Marietta and Kenesaw, Allatoona, Etowah Bridge, Kingston, Rome, Resaca, Dalton, Ringgold, and Chattanooga.  All the important bridges were likewise protected by good block-houses, admirably constructed, and capable of a strong defense against cavalry or infantry; and at nearly all the regular railroad-stations we had smaller detachments intrenched.  I had little fear of the enemy’s cavalry damaging our roads seriously, for they rarely made a break which could not be repaired in a few days; but it was absolutely necessary to keep General Hood’s infantry off our main route of communication and supply.  Forrest had with him in Middle Tennessee about eight thousand cavalry, and Hood’s army was estimated at from thirty-five to forty thousand men, infantry and artillery, including Wheeler’s cavalry, then about three thousand strong.

We crossed the Chattahoochee River during the 3d and 4th of October, rendezvoused at the old battle-field of Smyrna Camp, and the next day reached Marietta and Kenesaw.  The telegraph-wires had been cut above Marietta, and learning that heavy masses of infantry, artillery, and cavalry, had been seen from Kenesaw (marching north), I inferred that Allatoona was their objective point; and on the 4th of October I signaled from Mining’s Station to Kenesaw, and from Kenesaw to Allatoona, over the heads of the enemy, a message for General Corse, at Rome, to hurry back to the assistance of the garrison at Allatoona.  Allatoona was held by, a small brigade, commanded by Lieutenant-Colonel Tourtellotte, my present aide-de-camp.  He had two small redoubts on either side of the railroad, overlooking the village of Allatoona, and the warehouses, in which were stored over a million rations of bread.

Reaching Kenesaw Mountain about 8 a.m. of October 5th (a beautiful day), I had a superb view of the vast panorama to the north and west.  To the southwest, about Dallas, could be seen the smoke of camp-fires, indicating the presence of a large force of the enemy, and the whole line of railroad from Big Shanty up to Allatoona (full fifteen miles) was marked by the fires of the burning railroad.  We could plainly see the smoke of battle about, Allatoona, and hear the faint reverberation of the cannon.
