It was the same Union corps, the Eleventh, that had suffered so terribly at Chancellorsville under the hammer strokes of Jackson, and now it was routed again.
It practically dissolved for the time under the overwhelming rush on front and flank and became a mass of fugitives.
Harry heard for the first time that day the long, thrilling rebel yell of triumph, and both Howard and Doubleday, watching the battle intently, had become alarmed for their force.

Howard was already sending messages to Meade, telling him that the great battle had begun and begging him to hurry with the whole army.

Doubleday, seeing one flank crushed, was endeavoring to draw back the other, lest it be destroyed in its turn.
Harry and Dalton and all the Invincibles felt the thrill of triumph shooting through them.

They were advancing at last, making the first real progress of the day.
Harry felt that the days of Jackson had come back.

This was the way in which they had always driven the foe.
