Dr. Thatcher, in his 'Military Journal,' has given the closing particulars of this tragic scene. It follows:

"The principal guard-officer, who was constantly in the room with the prisoner, relates, that when the hour of his execution was announced to him in the morning, he received it without emotion; and while all present were affected with silent gloom, he retained a firm countenance, with calmness and composure of mind. Observing his servant enter the room in tears, he exclaimed, 'Leave me till you can show yourself more manly.' His breakfast being sent to him from the table of General Washington, which had been done every day of his confinement, he partook of it as usual; and having shaved and dressed himself, he placed his hat on the table, and cheerfully said to the guard-officers, 'I am ready at any moment, gentlemen, to wait on you.' The fatal hour having arrived, a large detachment of troops was paraded, and an immense concourse of people assembled; almost all our general and field officers, excepting his excellency and his staff, were present on horseback; melancholy and gloom pervaded all ranks; the scene was affecting and awful.

"I was so near during the solemn march to the fatal spot, as to observe every movement, and participate in every emotion which the melancholy scene was calculated to produce. Major Andre walked from the stone house, in which he had been confined, between two of our subaltern officers, arm in arm; the eyes of the immense multitude were fixed on him, who, rising superior to the fear of death, appeared as if conscious of the dignified deportment which he displayed. He betrayed no want of fortitude, but retained a complacent smile on his countenance, and politely bowed to several gentlemen whom he knew, which was respectfully returned. It was his earnest desire to be shot, as being the mode of death most conformable to the feelings of a military man, and he had indulged the hope that his request would be granted. At the moment, therefore, when suddenly he came in view of the gallows, he involuntarily started backward, and made a pause. 'Why this emotion, sir?' said an officer by his side. Instantly recovering his composure, he said, 'I am reconciled to my death, but I detest the mode.'

"While waiting, and standing near the gallows, I observed some degree of trepidation; placing his foot on a stone, and rolling it over, and choking in his throat, as if attempting to swallow. So soon, however, as he perceived that things were in readiness, he stepped quickly into the wagon, and at this moment he appeared to shrink; but instantly elevating his head with firmness, he said, 'It will be but a momentary pang;' and taking from his pocket two white handkerchiefs, the provost-marshal with one loosely pinioned his arms, and with the other, the victim, after taking off his hat and stock, bandaged his own eyes with perfect firmness, which melted the hearts, and moistened the cheeks, not only of his servant, but of the throng of spectators. The rope being appended to the gallows, he slipped the noose over his head, and adjusted it to his neck, without the assistance of the executioner. Colonel Scammell now informed him that he had opportunity to speak, if he desired it. He raised the handkerchief from his eyes, and said: 'I pray you to bear me witness, that I meet my fate like a brave man.' The wagon being now removed from under him, he was suspended, and instantly expired."

Thus was cut off in the morning of life a man full of promise and expectation—one to whose personal attractions were added accomplishments, rich, varied, and brilliant—destined, but for an untimely sacrifice of himself, under the impulse of a forbidden ambition, to have reached the goal of his wishes—honor and renown. His death at the hands of the Americans, according to the usage of war, was just; but to Arnold, the pioneer in the base transaction, the news of his execution must, it would seem, have been as the bitterness of death.

But no:—Arnold had no such feelings. Conscience was seared; the generous sympathies of our nature were extinct; even the honor of a soldier, dearer to him than life itself, had expired. The long-cherished, deep-rooted, sordid passion of his soul—avarice—alone lived; and now, while Andre, who might almost be said to be the victim of that nether spirit, was mouldering in an untimely and dishonored grave, he demanded his pay. What must Clinton—the friend and patron of the high-souled and magnanimous Andre—have felt when he told out to Arnold six thousand three hundred and fifteen pounds, as the reward of his treachery!

In addition to this pecuniary reward, Arnold received the commission of brigadier-general in the British army. But, after his infamous attack on New London, and his inhuman conduct to the brave Ledyard and his garrison in Fort Trumbull, finding himself neglected by the British officers, he obtained permission to retire to England, for which he sailed in 1781 with his family.

The life of Arnold was prolonged twenty years beyond this date. But although the king and a few others in office felt compelled to notice him for a time, yet they, at length, were willing to forget him, while others despised and shunned him. Colonel Gardiner says, that when a petition for a bill authorizing a negotiation of peace was presented to the king, Arnold was standing near the throne. Lauderdale is reported to have declared, on his return to the House of Commons, that, however gracious the language he had heard from the throne, his indignation could not but be highly excited at beholding, as he had done, his majesty supported by a traitor. And on another occasion, Lord Surrey, rising to speak in the House of Commons, and perceiving Arnold in the gallery, immediately sat down, exclaiming: "I will not speak while that man (pointing to him) is in the house."

Not long after the war, Arnold removed to St. John's, in New Brunswick, where he engaged for a time in the West India trade. Subsequently, he returned to England, where he resided to the time of his death, which occurred in London, June 14th, 1804.
