do by purchasing
the small "bunch" of stock he owned on the mountain. To this I
readily assented, and he started on the delicate undertaking. He
penetrated the enemy's lines with little difficulty, but while
prosecuting his search for information was suspected, and at once
arrested and placed under guard. From this critical situation he
escaped; however, making his way through the enemy's picket-line in
the darkness by crawling on his belly and deceiving the sentinels by
imitating the grunts of the half-wild, sand-colored hogs with which
the country abounded. He succeeded in reaching Rosecrans's
headquarters finally, and there gave the definite information that
Bragg intended to fight, and that he expected to be reinforced by
Longstreet.

By this time it was clear that Bragg had abandoned Chattanooga with
the sole design of striking us in detail as we followed in pursuit;
and to prevent his achieving this purpose orders came at 12 o'clock,
midnight, for McCook to draw in toward Chattanooga. This could be
done only by recrossing Lookout Mountain, the enemy's army at
Lafayette now interposing between us and Thomas's corps. The
retrograde march began at once. I moved back over the mountain on
the 13th and 14th to Stevens's Mills, and on the 15th and 16th
recrossed through Stevens's Gap, in the Lookout range, and encamped
at its base in McLamore's cove. The march was made with all possible
celerity, for the situation was critical and demanded every exertion.
The ascent and descent of the mountains was extremely exhausting, the
steep grades often rendering it necessary to drag up and let down by
hand both the transportation and artillery. But at last we were in
conjunction with the main army, and my division breathed easier.

On the 17th I remained in line of battle all day and night in front
of McLamore's cove, the enemy making slight demonstrations against me
from the direction of Lafayette. The main body of the army having
bodily moved to the left meanwhile, I followed it on the 18th,
encamping at Pond Spring. On the 19th I resumed the march to the
left and went into line of battle at Crawfish Springs to cover our
right and rear. Immediately after forming this line, I again became
isolated by the general movement to the left, and in consequence was
directed to advance and hold the ford of Chickamauga Creek at Lee and
Gordon's Mills, thus coming into close communication with the balance
of our forces. I mov
