The soldiers did not know where they were going, except that it was into the North, and they began to discuss the nature of the country they would find there.

Harry took the message to the Invincibles to pack and march.
Colonel Talbot and Lieutenant-Colonel St.Hilaire reluctantly dropped their unfinished game, put up the chessmen, and in an hour the Invincibles--few, but trim and strong--were marching to a position farther up the river.
The corps of Longstreet was to lead the way, and it would march the next morning.

Harry now knew that the army would advance by way of the Shenandoah valley.

The Northern troops had been raiding in the great valley and again had retaken Winchester, the pleasant little city so beloved of Jackson.

Harry shared the anger at this news that Jackson would have felt had he been alive to hear it.
Harry was well aware, however, that the army could not slip away from its opponent.
