oss Chattanooga Valley, using me
as a pivot for the purpose of crossing Missionary Ridge in the
neighborhood of Rossville. In the early part of the day I had driven
in the Confederate pickets in my front, so as to prolong my line of
battle on that of Wood, the necessity of continuing to refuse my
right having been obviated by the capture of Lookout Mountain and the
advance of Palmer.

About 2 o'clock orders came to carry the line at the foot of the
ridge, attacking at a signal of six guns. I had few changes or new
dispositions to make. Wagner's brigade, which was next to Wood's
division, was formed in double lines, and Harker's brigade took the
same formation on Wagner's right. Colonel F. T. Sherman's brigade
came on Harker's right, formed in a column of attack, with a front of
three regiments, he having nine. My whole front was covered with a
heavy line of skirmishers. These dispositions made, my right rested
a little distance south of Moore's road, my left joined Wood over
toward Orchard Knob, while my centre was opposite Thurman's house
--the headquarters of General Bragg--on Missionary Ridge. A small
stream of water ran parallel to my front, as far as which the ground
was covered by a thin patch of timber, and beyond the edge of the
timber was an open plain to the foot of Missionary Ridge, varying in
width from four to nine hundred yards. At the foot of the ridge was
the enemy's first line of rifle-pits; at a point midway up its face,
another line, incomplete; and on the crest was a third line, in which
Bragg had massed his artillery.

The enemy saw we were making dispositions for an attack, and in plain
view of my whole division he prepared himself for resistance,
marching regiments from his left flank with flying colors; and
filling up the spaces not already occupied in his intrenchments.
Seeing the enemy thus strengthening himself, it was plain that we
would have to act quickly if we expected to accomplish much, and I
already began to doubt the feasibility of our remaining in the first
line of rifle-pits when we should have carried them. I discussed the
order with Wagner, Harker, and Sherman, and they were similarly
impressed, so while anxiously awaiting the signal I sent Captain
Ransom of my staff to Granger, who was at Fort Wood, to ascertain if
we were to carry the first line or the ridge beyond. Shortly after
Ransom started the signal guns were fired, and I told my brigade
commanders to go for th
