, and another division started to follow but was
recalled. The object of Bragg's letter, no doubt, was in some way to
detain me until Knoxville could be captured, and his troops there be
returned to Chattanooga.

During the night of the 21st the rest of the pontoon boats, completed,
one hundred and sixteen in all, were carried up to and placed in North
Chickamauga. The material for the roadway over these was deposited out
of view of the enemy within a few hundred yards of the bank of the
Tennessee, where the north end of the bridge was to rest.

Hearing nothing from Burnside, and hearing much of the distress in
Washington on his account, I could no longer defer operations for his
relief. I determined, therefore, to do on the 23d, with the Army of the
Cumberland, what had been intended to be done on the 24th.

The position occupied by the Army of the Cumberland had been made very
strong for defence during the months it had been besieged. The line was
about a mile from the town, and extended from Citico Creek, a small
stream running near the base of Missionary Ridge and emptying into the
Tennessee about two miles below the mouth of the South Chickamauga, on
the left, to Chattanooga Creek on the right. All commanding points on
the line were well fortified and well equipped with artillery. The
important elevations within the line had all been carefully fortified
and supplied with a proper armament. Among the elevations so fortified
was one to the east of the town, named Fort Wood. It owed its
importance chiefly to the fact that it lay between the town and
Missionary Ridge, where most of the strength of the enemy was. Fort
Wood had in it twenty-two pieces of artillery, most of which would reach
the nearer points of the enemy's line. On the morning of the 23d
Thomas, according to instructions, moved Granger's corps of two
divisions, Sheridan and T. J. Wood commanding, to the foot of Fort Wood,
and formed them into line as if going on parade, Sheridan on the right,
Wood to the left, extending to or near Citico Creek. Palmer, commanding
the 14th corps, held that part of our line facing south and southwest.
He supported Sheridan with one division (Baird's), while his other
division under Johnson remained in the trenches, under arms, ready to be
moved to any point. Howard's corps was moved in rear of the centre. The
picket lines were within a few hundred yards of each other. At two
o'clock in the afternoon all were
