HEADQUARTERS, Frederick, September 13, 1862–12 m.

(Received 2.35 a. m., September 14.)

To the PRESIDENT:

I have the whole rebel force in front of me, but am confident, and no time shall be lost. I have a difficult task to perform, but with God's blessing will accomplish it. I think Lee has made a gross mistake, and that he will be severely punished for it. The army is in motion as rapidly as possible. I hope for a great success if the plans of the rebels remain unchanged. We have possession of Catoctin. I have all the plans of the rebels, and will catch them in their own trap if my men are equal to the emergency. I now feel that I can count on them as of old. All forces of Pennsylvania should be placed to co-operate at Chambersburg. My respects to Mrs. Lincoln. Received most enthusiastically by the ladies. Will send you trophies. All well, and with God's blessing will accomplish it.

GEO. B. McCLELLAN.
