rection an unobstructed view. I then saw General A. McD.
McCook's corps--the First-advancing toward Chaplin River by the
Mackville road, apparently unconscious that the Confederates were
present in force behind the stream. I tried by the use of signal
flags to get information of the situation to these troops, but my
efforts failed, and the leading regiments seemed to approach the
river indifferently prepared to meet the sudden attack that speedily
followed, delivered as it was from the chosen position of the enemy.
The fury of the Confederate assault soon halted this advance force,
and in a short time threw it into confusion, pushed it back a
considerable distance, and ultimately inflicted upon it such loss of
men and guns as to seriously cripple McCook's corps, and prevent for
the whole day further offensive movement on his part, though he
stoutly resisted the enemy's assaults until 4 o'clock in the
afternoon.

Seeing McCook so fiercely attacked, in order to aid him I advanced
Hescock's battery, supported by six regiments, to a very good
position in front of a belt of timber on my extreme left, where an
enfilading fire could be opened on that portion of the enemy
attacking the right of the First Corps, and also on his batteries
across Chaplin River. But at this juncture he placed two batteries
on my right and began to mass troops behind them, and General
Gilbert, fearing that my intrenched position on the heights might be
carried, directed me to withdraw Hescock and his supports and return
them to the pits. My recall was opportune, for I had no sooner got
back to my original line than the Confederates attacked me furiously,
advancing almost to my intrenchments, notwithstanding that a large
part of the ground over which they had to move was swept by a heavy
fire of canister from both my batteries. Before they had quite
reached us, however, our telling fire made them recoil, and as they
fell back, I directed an advance of my whole division, bringing up my
reserve regiments to occupy the crest of the hills; Colonel William
P. Carlin's brigade of Mitchell's division meanwhile moving forward
on my right to cover that flank. This advance pressed the enemy to
Perryville, but he retired in such good order that we gained nothing
but some favorable ground that enabled me to establish my batteries
in positions where they could again turn their attention to the
Confederates in front of McCook, whose critical condition was s
