WAR DEPARTMENT, Washington, September 15, 1863-4.30 p. m.

Major-General ROSECRANS,

Chattanooga, Tenn.:

From information received here to-day it is very probable that three divisions of Lee's army have been sent to re-enforce Bragg. All the available forces in the Departments of the Ohio and Cumberland should be brought to the front to meet the enemy. Sherman and Hurlbut will bring re-enforcements to the Tennessee River as rapidly as possible.

H. W. HALLECK,

General-in-Chief.

WAR DEPARTMENT, ADJUTANT-GENERAL'S OFFICE, Washington, D. C., September 15, 1863.

There being no draft in Indiana, officers and men who have been instructed to report at rendezvous at Indianapolis are ordered to return to their regiments.
