The accounts which we continue to receive in regard to the operations of our army under
Gen. Lee are cheering.
There is no longer any doubt that the advance of our army has crossed the
Potomac, and a portion of it has even penetrated
Pennsylvania.
We learn from a gentleman, who left
Martinsburg a few days ago, that on Tuesday last we had one division of infantry at
Hagerstown and others in the neighborhood, and that the cavalry commands of imboden and
Jenkins reached
Chambersburg on Tuesday night. On Wednesday morning they commenced the destruction of the public property at that place, and removing the stores southward.
Harper's Ferry is said to be invested by a corps of our army.
Everything indicates a general forward movement northward.
