Executive Mansion, September 11, 1862. 6 Pm

MAJOR-GENERAL McCLELLAN:

This is explanatory. If Porter, Heintzelman, and Sigel were sent you, it would sweep everything from the other side of the river, because the new troops have been distributed among them, as I understand. Porter reports himself 21,000 strong, which can only be by the addition of new troops. He is ordered tonight to join you as quickly as possible. I am for sending you all that can be spared, and I hope others can follow Porter very soon,

A. LINCOLN.
