By this time it was clear that Bragg intended to fall back behind the Tennessee River, and our only chance of accomplishing anything of importance was to smash up his rear-guard before it crossed the Cumberland Mountains, and in pursuance of this idea I was directed to attack such of his force as was holding on to Winchester. At 4 o’clock on the morning of July 2 I moved on that town, and when we got close to it directed my mounted troops to charge a small force of Confederate cavalry that was picketing their front. The Confederates resisted but little, and our men went with them in a disorderly chase through the village to Boiling Fork, a small stream about half a mile beyond. Here the fleeing pickets, rallying behind a stronger force, made a stand, and I was directed by McCook to delay till I ascertained if Davis’s division, which was to support me, had made the crossing of Elk River, and until I could open up communication with Brannan’s division, which was to come in on my left at Decherd. As soon as I learned that Davis was across I pushed on, but the delay had permitted the enemy to pull his rear-guard up on the mountain, and rendered nugatory all further efforts to hurt him materially, our only returns consisting in forcing him to relinquish a small amount of transportation and forage at the mouth of the pass just beyond Cowan, a station on the line of the Nashville and Chattanooga railroad.
At Cowan, Colonel Watkins, of the Sixth Kentucky Cavalry, reported to me with twelve hundred mounted men. Having heard during the night that the enemy had halted on the mountain near the University—an educational establishment on the summit—I directed Watkins to make a reconnoissance and find out the value of the information. He learned that Wharton’s brigade of cavalry was halted at the University to cover a moderately large force
