To the Officer commanding the forces around Fairfax Court-House:

General Pope directs that you furnish one regiment of infantry as an escort for a wagon train from Fairfax Court-House to Fairfax Station. Lieutenant Devin, Ninth Infantry, will call for the escort as he proceeds through the town.

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

GEO. D. RUGGLES,

Numbers 98. HEADQUARTERS ARMY OF VIRGINIA, Centreville, September 1, 1862-11 a. m.

Major-General HALLECK,

Washington:

The enemy is deploying his forces on the Little River pike, and preparing to advance by that road on Fairfax Court-House. This movement turns Centreville and interposes between us and Washington, and will force me to attack his advance, which I shall do as soon as his movement is sufficiently developed. I have nothing like the force you undoubtedly suppose, and the fight will be necessarily desperate. I hope you will make all preparations to make a vigorous defense of the entrenchments around Washington.

JNO. POPE,

Major-General, Commanding.

Numbers 99. CENTREVILLE, September 1, 1862-12 m.

Major-General McDOWELL:

Jackson is reported advancing on Fairfax with 20,000 men. Move quickly.

JNO. POPE,

Major-General, Commanding.
