Long trains of ambulances were bringing from the battle-field wounded men, who had been, since Saturday, exposed to the burning sun and the storm which had prevailed during Sunday night.

Temporary hospitals were established, and surgeons were actively employed in ministering to the relief of the unfortunate. Monday evening the battle of Glendale or Chantilly was fought, in the midst of a terrific thunder storm. The enemy, in attempting to turn our right, had been met by Hooker, Reno, McDowell and Kearney, and repulsed with heavy loss, from our entire front. But the victory was a costly one for us. The brave, earnest and accomplished soldier, Major-General Kearney, and the gallant Stevens, were both killed while leading their commands against the enemy.

The Sixth corps, on Monday evening, was marched back to Fairfax Court House; but early next morning returned within a mile of Centreville, when it took possession of the heights, and lay in line of battle until three o'clock P.M., when orders were received to march back to our old camp at Alexandria, which we reached at ten o'clock the same night; thus making in a single evening, a distance that had required two full days and a part of another, to march, in going out.

Thus ended General Pope's campaign in Virginia. Never was a campaign so misrepresented or so little understood; and never were the motives of men so falsely judged as were those of the generals connected with this campaign.

General Pope had fallen a victim to the foulest treachery of ambitious rivals, rather than to the strength of his open foes. Any one who will in candor trace the movements and the handling of that little army, when beset by an enemy now known to have been double its own strength, must concede that his plans were well conceived, and his generalship in this campaign fully equaled that which had won him so great renown in the west.

That the defeat of General Pope was brought about by the rivalry and jealousy of generals of the Union army cannot now be doubted. We know why Porter withheld the largest and freshest corps in the command from the fights, while its eleven thousand men were within sight of the battles; but why was the Sixth corps delayed? Some one was equally culpable with Porter. Was it worse to keep a corps out of the fight, when on the field, than to keep another corps off from the field altogether without any good reason? There can be but one question—who was responsible for the criminal neglect to send the Sixth corps to the assistance of Pope's army?

CHAPTER XIII.

THE MARYLAND CAMPAIGN.

General McClellan restored to command—March through Washington—Leisurely campaigning—Battle of Crampton Pass—Death of Mathison—Battle of South Mountain Pass—Death of Reno—Surrender of Harper's Ferry—March to Antietam.

General Pope, at his own request, was relieved from the command of the army, and General McClellan resumed the direction. Whatever might have been the real fitness of General Pope to command, his usefulness with the army just driven back upon the defenses of Washington, had departed. The return of General McClellan was hailed with joy by a large portion of the army.
