Maj.-Gen. MCCLELLAN,
Hdqrs. near Bolivar:

HARRISBURG, PA.,

September 15, 1862.

Your glorious message just received. Look out for Jackson's column from Harper's Ferry, where it has been fighting Miles for two days; also for Longstreet's column, which moved from Boonsborough last night to re-enforce Lee. It is thought that both will combine with Lee to give you another heavy battle. Gen. Reynolds has gone to Chambersburg, and will have the 10,000 militia there to-night; also 2,000 good cavalry. Part of them are from Harper's Ferry, under Col. Davis. They cut their way through last night, and report that Col. Miles would be obliged to surrender this morning, unless Jackson leaves to re-enforce Lee against your army.

A. G. CURTIN,
Governor of Pennsylvania.
