against General Adams with a brigade of troops at Rogersville, Ala.
At the same time Mitchel sent Colonel Lytle from Athens, Ala.,
to cooperate with Negley. On the 13th, the enemy learning of the
approach of the Federal forces, retreated across the Tennessee
River. This placed Mitchel in complete position of that portion
of Alabama north of that river. On May 29th, Mitchel concentrated
Negley's command from Columbia, Turchin's brigade from Huntsville,
and the Eighteenth Ohio under T. R. Stanley from Athens at Fayetteville
for an expedition against Chattanooga under the command of Negley.
These troops passed through Winchester, Cowen, and University Place
to Jasper. Advancing upon the latter place, the head of his column,
under Colonel Hambright, encountered a brigade of the enemy's troops
under General Adams. The enemy was driven from the place after a
sharp engagement, leaving his supply and ammunition trains. His
loss was 18 killed, 20 wounded, and 12 prisoners. Leaving Jasper,
Negley arrived on the north bank of the Tennessee, opposite
Chattanooga, on the 7th. Negley, on the evening of that day and the
morning of the next, bombarded Chattanooga, and made a demonstration
of crossing the river and attacking the town. General Duke says:
"The commandant of the place, General Leadbetter, had two or three
guns in battery and replied, when the gunners, who were the most

of the place was left entirely to the individual efforts of those
who chose to defend it, and nothing prevented its capture but the
fact that the enemy could not cross the river."

Negley then withdrew and encamped his command at Shelbyville.

General G. W. Morgan, under orders from Buell, assumed command of
the forces in Eastern Kentucky early in April. Acting under his
