Here André, being told that the papers found upon his person had been forwarded to Washington, addressed to him immediately the following lines: "I beg your Excellency will be persuaded that no alteration in the temper of my mind or apprehensions for my safety induces me to take the step of addressing you; but that it is to secure myself from the imputation of having assumed a mean character for treacherous purposes or self-interest.... It is to vindicate my fame that I speak, and not to solicit security. The person in your possession is Major John André, adjutant-general of the British army. The influence of one commander in the army of his adversary is an advantage taken in war. A correspondence for this purpose I held; as confidential (in the present instance) with his Excellency, Sir Henry Clinton. To favor it, I agreed to meet upon ground not within the posts of either army, a person who was to give me intelligence. I came up in the Vulture man-of-war for this effect, and was fetched from the shore to the beach. Being there, I was told that the approach of day would prevent my return, and that I must be concealed until the next night. I was in my regimentals, and had fairly risked my person. Against my stipulation, my intention, and without my knowledge beforehand, I was conducted within one of your posts. Thus was I betrayed into the vile condition of an enemy within your posts...."
This letter he submitted to the perusal of Major Tallmadge, who was surprised and agitated at finding the rank and importance of the prisoner he had in charge. The letter being despatched, and André's pride relieved on a sensitive point, he resumed his serenity, apparently unconscious of the awful responsibility of his situation.
On the very day that the treasonable conference between Arnold and André took place, on the banks of Haverstraw Bay, Washington had his interview with the French officers at Hartford. It led to no important result. Intelligence was received that the squadron of the Count de Guichen, on which they had relied to give them superiority by sea, had sailed for Europe. This disconcerted their plans, and Washington, in consequence, set out two or three days sooner than had been anticipated on his return to his head-quarters on the Hudson. He was accompanied by Lafayette and General Knox with their suites; also, part of the way, by Count Matthew Dumas, aide-de-camp to Rochambeau.
On approaching the Hudson, Washington took a more circuitous route than the one he had originally intended, striking the river at Fishkill, just above the Highlands, that he might visit West Point, and show the marquis the works which had been erected there during his absence in France. Circumstances detained them a night at Fishkill. Their baggage was sent on to Arnold's quarters in the Robinson House, with a message apprising the general that they would breakfast there the next day. In the morning (Sept. 24th) they were in the saddle before break of day, having a ride to make of eighteen miles through the mountains. When within a mile of the Robinson House, Washington turned down a cross road leading to the banks of the Hudson. Lafayette apprised him that he was going out of the way, and hinted that Mrs. Arnold must be waiting breakfast for him. "Ah, marquis!" replied he good-humoredly, "you young men are all in love with Mrs. Arnold. Go you and breakfast with her, and tell her not to wait for me. I must ride down and examine the redoubts on this side of the river, but will be with her shortly." The marquis and General Knox, however, turned off and accompanied him down to the redoubts, while Colonel Hamilton and Lafayette's aide-de-camp, Major James McHenry, continued along the main road to the Robinson House, bearing Washington's apology, and request that the breakfast might not be retarded.
The family with the two aides-de-camp sat down to breakfast. Mrs. Arnold had arrived but four or five days previously from Philadelphia, with her infant child, then about six months old. She was bright and amiable as usual. Arnold was silent and gloomy. It was an anxious moment with him. In the midst of the repast a horseman alighted at the gate. It was the messenger bearing Jameson's letter to Arnold, stating the capture of André, and that dangerous papers found on him had been forwarded to Washington. The mine had exploded beneath Arnold's feet. Controlling the dismay that must have smitten him to the heart, he beckoned Mrs. Arnold from the breakfast table, signifying a wish to speak with her in private. When alone with her in her room up-stairs, he announced in hurried words that he was a ruined man, and must instantly fly for his life! Overcome by the shock, she fell senseless on the floor. Without pausing to aid her, he hurried down stairs, informed his guests that he must haste to West Point to prepare for the reception of the commander-in-chief; and mounting the horse of the messenger, which stood saddled at the door, galloped down to the landing-place, where his six-oared barge was moored. Throwing himself into it, he ordered his men to pull out into the middle of the river, and then made down with all speed for Teller's Point.
Washington arrived at the Robinson House shortly after the flight of the traitor. Being informed that Mrs. Arnold was in her room, unwell, and that Arnold had gone to West Point to receive him, he took a hasty breakfast, and repaired to the fortress, leaving word that he and his suite would return to dinner.
He remained at the Point throughout the morning inspecting the fortifications. In the meantime, the messenger whom Jameson had despatched to Hartford with a letter covering the papers taken on André, arrived at the Robinson House. He had learnt, while on the way to Hartford, that Washington had left that place, whereupon he turned bridle to overtake him, but missed him in consequence of the general's change of route. Coming by the lower road, the messenger had passed through Salem, where André was confined, and brought with him the letter written by that unfortunate officer to the commander-in-chief, the purport of which has already been given. These letters being represented as of the utmost moment, were opened and read by Colonel Hamilton, as Washington's aide-de-camp and confidential officer. He maintained silence as to their contents; met Washington, as he and his companions were coming up from the river, on their return from West Point, spoke to him a few words in a low voice, and they retired together into the house. Whatever agitation Washington may have felt when these documents of deep-laid treachery were put before him, he wore his usual air of equanimity when he rejoined his companions. Taking Knox and Lafayette aside, he communicated to them the intelligence, and placed the papers in their hands.
His first idea was to arrest the traitor. Conjecturing the direction of his flight, he despatched Colonel Hamilton on horseback to spur with all speed to Verplanck's Point, with orders to the commander to intercept Arnold should he not already have passed that post. In the meantime, Arnold, panic-stricken, had sped his caitiff flight through the Highlands; infamy howling in his rear; arrest threatening him in the advance; a fugitive past the posts which he had recently commanded; shrinking at the sight of that flag which hitherto it had been his glory to defend!
He had passed through the Highlands in safety, but there were the batteries at Verplanck's Point yet to fear. Fortunately for him, Hamilton, with the order for his arrest had not arrived there. His barge was known by the garrison. A white handkerchief displayed gave it the sanction of a flag of truce: it was suffered to pass without question, and the traitor effected his escape to the Vulture sloop-of-war, anchored a few miles below. As if to consummate his degradation by a despicable act of treachery and meanness, he gave up to the commander his coxswain and six bargemen as prisoners of war. We are happy to add that this perfidy excited the scorn of the British officers; and, when it was found that the men had supposed they were acting under the protection of a flag, they were released by order of Sir Henry Clinton.
Colonel Hamilton returned to the Robinson House and reported the escape of the traitor. He brought two letters also to Washington, which had been sent on shore from the Vulture, under a flag of truce. One was from Arnold, in which he wrote: "I ask no favor for myself. I have too often experienced the ingratitude of my country to attempt it; but, from the known humanity of your Excellency, I am induced to ask your protection for Mrs. Arnold from every insult and injury that a mistaken vengeance of my country may expose her to.... I beg she may be permitted to return to her friends in Philadelphia, or to come to me as she may choose." The other letter was from Colonel Beverley Robinson, interceding for the release of André, on the plea that he was on shore under the sanction of a flag of truce, at the request of Arnold.
