COMPLIMENTARY ORDERS.

ORDERS.] HDQRS. DEPARTMENT OF THE CUMBERLAND, Chattanooga, October 2, 1863.

ARMY OF THE CUMBERLAND:

You have made a grand and successful campaign. You have driven the rebels from Middle Tennessee.

You crossed a great mountain range, placed yourselves on the banks of a broad river, crossed it in the face of a powerful opposing army, and crossed two other great mountain ranges at the only practicable passes some 40 miles between extremes. you concentrated in the face of superior numbers, fought the combined armies of Bragg, which you drove from Shelbyville and Tullahoma; of Johnston's army from Mississippi, and the tried veterans of Longstreet's corps, and for two days held them at bay, giving them blow for blow with heavy interest. When the day closed you held the field, from which you withdrew in the face of overpowering numbers, to occupy the point for which you set out - Chattanooga.

You have accomplished the great work of the campaign. You hold the key of East Tennessee, of North Georgia, and of the enemy's mines of coal and niter.

Let these achievements console you for the regret you experience that arrivals of fresh hostile troops forbad your remaining on the field to renew the battle for the right of burying your gallant dead, and caring for your brave companions who lay wounded on the field. The losses you have sustained, though heavy, are slight considering the odds against you and the stake you have won. You hold in your hands the substantial fruits of a victory, and deserve and will receive the honor and plaudits of a grateful nation which asks nothing of even those who have been fighting us but obedience to the constitution and laws established for our common benefit.

The general commanding earnestly begs every officer and soldier of this army to unite with him in thanking Almighty God for his favor to us. He presents his hearty thanks and congratulations to all the officers soldiers of this command for their energy, patience, and perseverance, and the undaunted courage displayed by those who fought with such unflinching resolution.

Neither the history of this was nor probably the annals of any battle furnish a loftier example of obstinate bravery and enduring resistance to superior number, when troops, having exhausted their ammunition, resorted to the bayonet so many times to hold their position against such odds as did our left and center on the afternoon of the 20th of September, at the battle of Chickamauga.
