It had been expected by Buell that he would fight the enemy on the 9th of October, but the Confederates disposed of that proposition by attacking us on the 8th, thus disarranging a tactical conception which, with our superior numbers, would doubtless have proved successful had it not been anticipated by an enterprising foe.  During the battle on the 8th the Second Corps, under General Thomas L. Crittenden, accompanied by General George H. Thomas, lay idle the whole day for want of orders, although it was near enough to the field to take an active part in the fight; and, moreover, a large part of Gilbert’s corps was unengaged during the pressure on McCook.  Had these troops been put in on the enemy’s left at any time after he assaulted McCook, success would have been beyond question; but there was no one on the ground authorized to take advantage of the situation, and the battle of Perryville remains in history an example of lost opportunities.  This was due in some measure probably to General Buell’s accident, but is mainly attributable to the fact that he did not clearly apprehend Bragg’s aim, which was to gain time to withdraw behind Dick’s River all the troops he had in Kentucky, for the Confederate general had no idea of risking the fate of his army on one general battle at a place or on a day to be chosen by the Union commander.

Considering the number of troops actually engaged, the losses to Buell were severe, amounting to something over five thousand in killed, wounded, and missing.  Among the killed were two brigade commanders of much promise—­General James S. Jackson and General William R. Terrill.  McCook’s corps lost twelve guns, some of which were recovered next day.  The enemy’s loss in killed and wounded we never learned, but it must have equalled ours; and about four thousand prisoners, consisting principally of sick and wounded, fell into our hands.  In the first report of the battle sent North to the newspapers I was reported among the killed; but I was pleased to notice, when the papers reached us a few days later, that the error had been corrected before my obituary could be written.

The enemy retired from our front the night of the 8th, falling back on Harrodsburg to form a junction with Kirby Smith, and by taking this line of retreat opened to us the road to Danville and the chance for a direct march against his depot of supplies at Bryantsville.  We did not take advantage of this opening, however, and late in the day —­on the 9th—­my division marched in pursuit, in the direction of Harrodsburg, which was the apex of a triangle having for its base a line from Perryville to Danville.  The pursuit was slow, very slow, consuming the evening of the 9th and all of the 10th and 11th.  By cutting across the triangle spoken of above, just south of the apex, I struck the Harrodsburg-Danville road, near Cave Springs, joining there Gilbert’s left division, which had preceded me and marched through Harrodsburg.  Here we again rested until the intention
