e. By this time the
clouds had lifted so that the enemy could see from his elevated position
all that was going on. The signal for advance was given by a booming of
cannon from Fort Wood and other points on the line. The rebel pickets
were soon driven back upon the main guards, which occupied minor and
detached heights between the main ridge and our lines. These too were
carried before halting, and before the enemy had time to reinforce their
advance guards. But it was not without loss on both sides. This
movement secured to us a line fully a mile in advance of the one we
occupied in the morning, and the one which the enemy had occupied up to
this time. The fortifications were rapidly turned to face the other
way. During the following night they were made strong. We lost in this
preliminary action about eleven hundred killed and wounded, while the
enemy probably lost quite as heavily, including the prisoners that were
captured. With the exception of the firing of artillery, kept up from
Missionary Ridge and Fort Wood until night closed in, this ended the
fighting for the first day.

The advantage was greatly on our side now, and if I could only have been
assured that Burnside could hold out ten days longer I should have
rested more easily. But we were doing the best we could for him and the
cause.

By the night of the 23d Sherman's command was in a position to move,
though one division (Osterhaus's) had not yet crossed the river at
Brown's Ferry. The continuous rise in the Tennessee had rendered it
impossible to keep the bridge at that point in condition for troops to
cross; but I was determined to move that night even without this
division. Orders were sent to Osterhaus accordingly to report to
Hooker, if he could not cross by eight o'clock on the morning of the
24th. Because of the break in the bridge, Hooker's orders were again
changed, but this time only back to those first given to him.

General W. F. Smith had been assigned to duty as Chief Engineer of the
Military Division. To him were given the general direction of moving
troops by the boats from North Chickamauga, laying the bridge after they
reached their position, and generally all the duties pertaining to his
office of chief engineer. During the night General Morgan L. Smith's
division was marched to the point where the pontoons were, and the
brigade of Giles A. Smith was selected for the delicate duty of manning
the boats and surprising the
