Everything seemed to Harry's excited mind to stand out gigantic and magnified.

Black specks began to dance in myriads before his eyes.

He heard beside him the sharp, panting breath of his comrades, and the beat of many feet as they rushed on.
He saw the Northern officers on the earthwork disappear, dropping down behind, and the young Southern soldiers raised a great shout of triumph which, as it sank on its dying note, was merged into a tremendous crash.
The whole fort seemed to Harry to blaze with red fire, as the heavy guns were fired straight into the faces of the Invincibles.

The roar of the cannon was so near that Harry, for an instant, was deafened by the crash.

Then he heard groans and cries and saw men falling around him.
In another moment came the swish of rifle bullets, and the ranks of the Invincibles were cut and torn with lead.
