General PATTERSON, ; Comdg. U. 8. Forces at or near Chambersburg, Pa. :

Whereas Lieutenant-General Scott has authorized me, by an accredited messenger, to make a requisition upon you for a detachment of troops, to be sent to Frederick City, if in my discretion I deem it necessary for the public welfare; and whereas the city of Frederick is at any moment liable to attack by the rebels at Harper’s Ferry and vicinity ; and whereas stores and provisions are daily sent from this city and vicinity to Virginia, in aid and comfort of the enemy, I having no means at my disposal of preventing said transportation of stores and provisions:

Now, therefore, I, Thomas H. Hicks, governor of Maryland, do, by this my requisition, call upon you for such detachment of the troops under your command as you, in your military knowledge, may deem sufficient for the purposes indicated, provided your response for this requisition will not interfere with the safety of the great interests confided to you.

I have the honor to be, with high respect, your obedient servant,
