The officer commanding picket at Freeman's Ford reports all quiet. General warren is about 3 miles in my rear and left. It is my impression that at least one corps of Lee's army is in my front.

I am, sir, very respectfully, your obedient servant,

J. IRVIN GREGG,

Colonel, Commanding Brigade.

[P. S.]-A staff officer, just returned from Colonel Gregg's command, reports the picket line not yet established at Rappahannock Bridge. The enemy to-day advanced toward Bealeton, but were driven back.

HEADQUARTERS CAVALRY CORPS,
October 23, 1863.

Respectfully forwarded to General Humphreys, chief of staff.

General Gregg's indorsement that the enemy were driven back does not indicate a large force on this side of the river.

Major-General.

GENERAL: I found the enemy in force at Rappahannock Station last evening. Drove them behind the works at that place. This morning I found them still there, and disposed to fight.

I have directed my advance to fall back on Fayetteville in case the enemy push them. My own camp is about 1 mile from Fayetteville, on the Warrenton road.

Very respectfully, your obedient servant,

J. IRVIN GREGG,

Colonel, Commanding Brigade.

Major-General WARREN,

Commanding Second Army Corps.

I am all ready for anything at Turkey Run.
