Still Another Account.

Alexandria is taken, but at a heavy cost.

Col. Ellsworth is killed. He was shot dead while descending the stairs of the Marshall House with a secession flag which he had torn down from a staff on the roof.

The man who shot him was dispatched by Francis E. Brownell, of Troy, N.Y. a private of Company A, in Col. Ellsworth's Regiment. The retribution was instantaneous. The Col. was shot through the breast by one charge of a double barreled gun, the other charge entering a wainscoting near him.

He fell on his face only exclaiming “My God,” and the blood gushed from his wound with such profusion as to drench the entire passage.

A few seconds afterwards he uttered a low moan, but his eyes were instantly fixed, and he had ceased to breathe.

The house was in the utmost confusion. The lodgers darted from their rooms, but were held in control by the four or five Zouaves who accompanied the Colonel, and who at once established and maintained order.

It was a long time before a reinforcement arrived, and it was almost thought we might be hemmed in by the number of persons in the house, which was considerable. But the trepidation too great for any organization nothing of the sort was attempted, although I think that the Zouaves, mad with grief at the loss of their leader, would have been but little disappointed if it had been.

He was laid upon a bed in a room near at hand with the Rebel flag stained with his blood, and low a trophy to his glory, about his feet. The Surgeon, who soon arrived, satisfied us that he had expired at the moment of being shot.

The man who killed him was James W. Jackson, who proved to be the keeper of the house. He must have died as suddenly. He was shot through the bead, and afterward ran through the body by the saber bayonet of the same private.

His wife presently discovered the fatality, and approaching the body uttered the most agonizing cries, and although treated with the utmost consideration that could be offered her in her misery she remained for a long time in the wildest state of frenzy.

The 1st Michigan Regiment entered Alexandria at about 6 o'clock, an hour after the appearance of the Zouaves, and captured a body of cavalry who at first demanded time to consider their surrender, but were forced to yield their arms with, out delay. Other regiments are expected.

Col. Ellsworth was the only person of our side killed. Surgeon Gray made an examination, and discovered that the slugs from the gun entered between the third and fifth rib, shattering the fourth rib, and pushed into the left auricle of the heart, destroying all the integuments with which it came in contact. The Colonel was conveyed up to Washington in the steamer James Guy.

The persons who were around him at the moment of his fall returned to him. His remains will lie in the Navy Yard until proper solemnities are prepared by the authorities.

The occupation of Alexandria, so far as the action of the Zouaves was concerned, was a thorough success. They were the first regiment to arrive, They went by water from their encampment and reached Alexandria a little after dawn. The rebel sentries fired an alarm and fled. The town was entered without resistance, and but for the melancholy event which now seems to overshadow the success of the expedition, no gloom upon its brilliancy could be seen.
