advance. By noon Geary
had gained the open ground on the north slope of the mountain, with his
right close up to the base of the upper palisade, but there were strong
fortifications in his front. The rest of the command coming up, a line
was formed from the base of the upper palisade to the mouth of
Chattanooga Creek.

Thomas and I were on the top of Orchard Knob. Hooker's advance now made
our line a continuous one. It was in full view, extending from the
Tennessee River, where Sherman had crossed, up Chickamauga River to the
base of Mission Ridge, over the top of the north end of the ridge to
Chattanooga Valley, then along parallel to the ridge a mile or more,
across the valley to the mouth of Chattanooga Creek, thence up the slope
of Lookout Mountain to the foot of the upper palisade. The day was
hazy, so that Hooker's operations were not visible to us except at
moments when the clouds would rise. But the sound of his artillery and
musketry was heard incessantly. The enemy on his front was partially
fortified, but was soon driven out of his works. During the afternoon
the clouds, which had so obscured the top of Lookout all day as to hide
whatever was going on from the view of those below, settled down and
made it so dark where Hooker was as to stop operations for the time. At
four o'clock Hooker reported his position as impregnable. By a little
after five direct communication was established, and a brigade of troops
was sent from Chattanooga to reinforce him. These troops had to cross
Chattanooga Creek and met with some opposition, but soon overcame it,
and by night the commander, General Carlin, reported to Hooker and was
assigned to his left. I now telegraphed to Washington: "The fight
to-day progressed favorably. Sherman carried the end of Missionary
Ridge, and his right is now at the tunnel, and his left at Chickamauga
Creek. Troops from Lookout Valley carried the point of the mountain, and
now hold the eastern slope and a point high up. Hooker reports two
thousand prisoners taken, besides which a small number have fallen into
our hands from Missionary Ridge." The next day the President replied:
"Your dispatches as to fighting on Monday and Tuesday are here. Well
done. Many thanks to all. Remember Burnside." And Halleck also
telegraphed: "I congratulate you on the success thus far of your plans.
I fear that Burnside is hard pushed, and that any further delay may
prove fatal. I know you will do
