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.

From Kenesaw I ordered the Twenty-third Corps (General Cox) to march due west on the Burnt Hickory road, and to burn houses or piles of brush as it progressed, to indicate the head of column, hoping to interpose this corps between Hood’s main army at Dallas and the detachment then assailing Allatoona.  The rest of the army was directed straight for Allatoona, northwest, distant eighteen miles.  The signal-officer on Kenesaw reported that since daylight he had failed to obtain any answer to his call for Allatoona; but, while I was with him, he caught a faint glimpse of the tell-tale flag through an embrasure, and after much time he made out these letters-” C.,” “R.,” “S.,” “E.,” “H.,” “E.,” “R.,” and translated the message—­“Corse is here.”  It was a source of great relief, for it gave me the first assurance that General Corse had received his orders, and that the place was adequately garrisoned.

I watched with painful suspense the indications of the battle raging there, and was dreadfully impatient at the slow progress of the relieving column, whose advance was marked by the smokes which were made according to orders, but about 2 p.m.  I noticed with satisfaction that the smoke of battle about Allatoona grew less and less, and ceased altogether about 4 p.m.  For a time I attributed this result to the effect of General Cog’s march, but later in the afternoon the signal-flag announced the welcome tidings that the attack had been fairly repulsed, but that General Corse was wounded.  The next day my aide, Colonel Dayton, received this characteristic dispatch:
