ation in his front, to determine the truth or falsity of the
information that had been received. This task fell to the Fourth
Corps, and at 12 o'clock on the 23d I was notified that Wood's
division would make a reconnoissance to an elevated point in its
front called Orchard Knob, and that I was to support it with my
division and prevent Wood's right flank from being turned by an
advance of the enemy on Moore's road or from the direction of
Rossville. For this duty I marched my division out of the works
about 2 p.m., and took up a position on Bushy Knob. Shortly after we
reached this point Wood's division passed my left flank on its
reconnoissance, and my command, moving in support of it, drove in the
enemy's picket-line. Wood's took possession of Orchard Knob easily,
and mine was halted on a low ridge to the right of the Knob, where I
was directed by General Thomas to cover my front by a strong line of
rifle-pits, and to put in position two batteries of the Fourth
regular artillery that had joined me from the Eleventh Corps. After
dark Wood began to feel uneasy about his right flank, for a gap
existed between it and my left, so I moved in closer to him, taking
up a line where I remained inactive till the 25th, but suffering some
inconvenience from the enemy's shells.

On the 24th General Sherman made an attack for the purpose of
carrying the north end of Missionary Ridge. His success was not
complete, although at the time it was reported throughout the army to
be so. It had the effect of disconcerting Bragg, however, and caused
him to strengthen his right by withdrawing troops from his left,
which circumstance led Hooker to advance on the northerly face of
Lookout Mountain. At first, with good glasses, we could plainly see
Hooker's troops driving the Confederates up the face of the mountain.
All were soon lost to view in the dense timber, but emerged again on
the open ground, across which the Confederates retreated at a lively
pace, followed by the pursuing line, which was led by a color-bearer,
who, far in advance, was bravely waving on his comrades. The
gallantry of this man elicited much enthusiasm among us all, but as
he was a considerable distance ahead of his comrades I expected to
see his rashness punished at any moment by death or capture. He
finally got quite near the retreating Confederates, when suddenly
they made a dash at him, but he was fully alive to such a move, and
ran back, apparently uninju
