One of the Tribune correspondents had not left the army since the Peninsular campaign, and, remaining constantly within the lines, his position had never been questioned. Another, who had a nominal appointment upon the staff of a major-general, wore a saber and passed for an officer. I had an old pass, without date, from General Burnside, authorizing the bearer to go to and fro from his head-quarters at all times, which enabled me to go by all guards with ease.

Marcy engaged lodgings at the house for McClellan; but an hour after, a message was received that the general thought it better to sleep upon the ground, near the bivouac-fires, as an example for the troops.

Shameful Surrender of Harper's Ferry.

Last night came intelligence of the surrender, to Stonewall Jackson, of Harper's Ferry, including the impregnable position of Maryland Hights and our army.

Colonel Miles, who commanded, atoned for his weakness with his life, being killed by a stray shot just after he had capitulated. Colonel Thomas H. Ford, ex-Lieutenant-Governor of Ohio, who was stationed on the Hights, professed to have a written order from Miles, his superior officer, to exercise his own discretion about evacuating; but he could not exhibit the paper, and stated that he had lost it. He gave up that key to the position without a struggle. It was like leaving the rim of a teacup, to go down to the bottom for a defensive point. He was afterward tried before a court-martial, but saved from punishment, and permitted to resign, through the clemency of President Lincoln. In any other country he would have been shot.

On September 16th, General McClellan established his head-quarters in a great shaded brick farm-house.

Under one of the old trees sat General Sumner, at sixty-four erect, agile, and soldierly, with snow-white hair. A few yards distant, in an open field, a party of officers were suddenly startled by two shells which dropped very near them. The group broke up and scattered with great alacrity.

"Why," remarked Sumner, with a peculiar smile, "the shells seem to excite a good deal of commotion among those young gentlemen!"

It appeared to amuse and surprise the old war-horse that anybody should be startled by bullets or shots.
