along the line of the railroad. The telegraph line is completed to these headquarters and awaits an operator. A scouting party from my command surprised a camp of guerrillas last night, numbering about 12 men. In the darkness they succeeded in escaping. We recaptured 1 man, 2 negroes, and 3 horses.

These guerrillas number about 50 men, including scouts, citizens, and soldiers. They have furnished accurate information of our movements to the enemy. One hundred men of my command are now in pursuit and must capture them. I shall arrest all citizens who assist these men or know of their whereabouts. I am compelled to do this to secure my telegraph line and communication. All is quiet along my line. The enemy's pickets and stragglers at Fredericksburg number upward of 1,000 men.

I forward four Richmond papers, of different dates, received from my pickets.

Very respectfully,

J. KILPATRICK,

Brigadier General of Vols., Commanding Third Division.
