. COLONEL: I am directed by the brigadier-general commanding to inform you that he received late last evening from the headquarters of

> SY dd a a uet. UM nr a E AST ae US = X S OF E : z s y the Army of the Potomac instructions for you to proceed to Fredericktown and Saint Leonard’s, and gain all the information possible regarding the designs and movements of the enemy, capturing such organized parties as you may meet with, and taking all the arms and munitions of war you may fall in with; but you will not allow your men to depredate upon citizens who attend to their own legitimate business and do not afford aid to the enemy, even if they are secessionists. When . this is executed, you Will return to Lower Marlborough and await further orders. — ;

The general is also informed that Colonel Dwight is ordered to Port Tobacco. The necessary supplies will be forwarded to you; but in order to do this it is necessary for you to report the strength of your command and the most direct route over which they should be forwarded to Lower Marlborough. This you can determine from your own observation.. Stores forwarded to you yesterday were dispatched in season to reach you at Lower Marlborough that day, and it was expected that on the receipt of this information you would have halted your command if on the march, if you did not return to that point. If, on inquiry, you should find that you have not on hand rations for your whole command for the time necessary for you to execute the foregoing instructions, you will divide it, and send forward as large a party as you are able to find. If the teamsters return in season, additional supplies will be sent from here to-morrow, and should be able to reach Lower Marlborough the same night.

It is presumed that you are senior officer to Colonel Dwight.

Very respectfully, your obedient servant,
