HEADQUARTERS OF THE ARMY, July 27, 1861

Washington, July 27, 1861.

Major-General Banks, U. S. A., Harper’s Ferry, Va.:

I have ordered Captain Newton back to you. I do not ask that you shall attempt to hold Harper’s Ferry at a great hazard even after being largely re-enforced. With less than 15,000 men, and a probability of being attacked by 20,000, it may be better to cross the Potomac and take up position on Maryland Heights and opposite to Leesburg. Give me your views.
