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 ready to advance. 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 q
