is much more gradual, and a good wagon road, zigzagging
up it, connects the town of Chattanooga with the summit.
Early on the morning of the 24th Hooker moved Geary's division,
supported by a brigade of Cruft's, up Lookout Creek, to effect a
crossing. The remainder of Cruft's division was to seize the bridge
over the creek, near the crossing of the railroad. Osterhaus was to move
up to the bridge and cross it. The bridge was seized by Gross's brigade
after a slight skirmish with the pickets guarding it. This attracted
the enemy so that Geary's movement farther up was not observed. A heavy
mist obscured him from the view of the troops on the top of the
mountain. He crossed the creek almost unobserved, and captured the
picket of over forty men on guard near by. He then commenced ascending
the mountain directly in his front. By this time the enemy was seen
coming down from their camps on the mountain slope, and filing into
their rifle-pits to contest the crossing of the bridge. By eleven
o'clock the bridge was complete. Osterhaus was up, and after some sharp
skirmishing the enemy was driven away with considerable loss in killed
and captured.
While the operations at the bridge were progressing, Geary was pushing
up the hill over great obstacles, resisted by the enemy directly in his
front, and in face of the guns on top of the mountain. The enemy,
seeing their left flank and rear menaced, gave way, and were followed by
Cruft and Osterhaus. Soon these were up abreast of Geary, and the whole
command pushed up the hill, driving the enemy in 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
momen
