The Yankees were not alone in destroying bridges.

HEADQUARTERS,
November 29, 1863.
General VAUGHN:
If the enemy is anywhere in your rear, start at once, to join me here. Have all of the public property hauled off with you. If your rear is exposed for want of cavalry, you can move up and join us, leaving what cavalry you have as picket guard at the river. Let your cavalry put itself in communication with Colonel Hart at Kingston, if you come on to join us. Let Colonel Hart give orders to this picket, and keep us advised of the enemy's movements. If your information of the enemy's movements in your rear is such as to warrant your coming up to us, destroy all public property, such as bridges, that you cannot bring off. Any surplus of provisions give to the citizens.
Respectfully,
J. LONGSTREET,
Lieutenant-General. (OR 31/3, 761)

Brig. Gen. JOHN C. VAUGHN,
Loudon:
If you are obliged to evacuate, destroy everything that might be useful to the enemy.
J. LONGSTREET,
Lieutenant-General.
Keep us advised of the enemy and his strength. (OR 31/3, 762)

HEADQUARTERS, December 2, 1863--7 p.m.
Brig. Gen. JOHN C. VAUGHN,
Commanding, &c., Loudon:
GENERAL: The commanding general directs that you retire from Loudon at once, with your infantry and artillery, and march to join us here. Bring with you all the stores and supplies that you can, and destroy all that you are obliged to leave. Leave your cavalry behind you to cover your movement; observe the enemy and destroy the bridge and other means of crossing the river.
Be sure that the bridge is effectually destroyed. Report frequently your progress and movements.
I am, general, very respectfully, your obedient servant,
G. M. SORREL,
Lieutenant-Colonel, Assistant Adjutant-General. (OR 31/3, 779)

On the 2d of December, the army moved rapidly north toward Loudon, 26 miles distant.
About 11 a.m. the cavalry passed to the head of the column and was ordered to push to Loudon, and, if possible, save a pontoon bridge across the Tennessee, held by a brigade of the enemy, commanded by General Vaughn. The cavalry moved with such rapidity as to capture every picket, but the brigade of Vaughn had artillery in position covered by earth-works, and displayed a force too respectable to be carried by a cavalry dash, and darkness closed in before General Howard's infantry got up. The enemy abandoned the place in the night, destroying the pontoons, running 3 locomotives and 48 cars into the Tennessee, and abandoning a large quantity of provisions, four guns, and other matériel, which General Howard took at daylight.
But the bridge was gone, and we were forced to turn east and trust to General Burnside's bridge at Knoxville. (OR 31/1?[2], 578, MGen. W. T. Sherman)
