HEADQUARTERS ARMY OF TENNESSEE,
In the Field, Leet's Tan-yard, September 18, 1863-11 p.m.
Commanding Cavalry Corps:
GENERAL: The enemy have crossed at Owens' Ford in force. Place yourself across their line of march and retard their movement, covering General Hill, until the movement on our right flank is completed in the morning.
I am, general, very respectfully, your obedient servant,
HEADQUARTERS HILL'S CORPS,
Anderson's House, September 18, 1863-8.40 p.m.
Owens' Ford was lost to-day. Armstrong is now picketing with some 60 men from Childress' Ford to Glass' Mil, a distance of 2 1/2 miles.

I have the honor to be, general, your obedient servant,
HEADQUARTERS CAVALRY CORPS,
One Mile from Anderson's, September 18, 1863.
GENERAL: I have just seen General Bragg, and he directs that all my command should be used to guard the left flank of the army, and it will therefore be impossible for me to relieve General Armstrong's brigade. This will, I think, only be necessary until the position of the enemy is more fully developed.
Colonel Wheeler, who now commands General Armstrong's brigade is making arrangements to send more cavalry to your front. General Bragg states that General Hill will be up in time to prevent any gaps between your line and his.
Very respectfully, general, your obedient servant,
HEADQUARTERS MARTIN'S CAVALRY DIVISION,
Catlett's Gap, September 18, 1863-11.40 a.m.
The enemy is keeping up a heavy dust. I believe the force in the cove is moving toward the mouth of the cove in the direction of Chattanooga. Opposite and a little northwest of this gap there are
