Arnold left him and went up the river in his own barge to head-quarters. Before he departed from Smith's House, he urged Smith to go back with André to the Vulture as soon as it should be dark; yet the matter seems to have been undecided, for he wrote and gave to Smith two passports (dating them "Head-Quarters"), one authorizing him to go by water, and the other by land. The former was in these words. "Joshua Smith has permission to pass with a boat and three hands and a flag to Dobbs's Ferry, on public business, and to return immediately." The latter said, "Joshua Smith has permission to pass the guards to the White Plains and to return, he being on public business by my direction." To this was added a third, as follows. "Permit Mr. John Anderson to pass the guards to the White Plains, or below if he chooses, he being on public business by my direction." This last was the paper presented by André to his captors when he was taken. All these passports were in the handwriting of Arnold and signed by him.

André passed the day in solitude, and as it drew near to a close, he was impatient to be ready for his departure. On consulting Smith, he found him obstinately determined not to return to the Vulture, and that he had neither spoken to the watermen nor made any other preparation.

The reason he gave afterwards for this refusal was, that his ague had attacked him severely, and the state of his health would not admit of an exposure in the boat. But the fact of his agreeing to accompany André on horseback, and to travel with him several hours in the night, was a proof that this was not the true ground of his objection. It was absurd to talk of being too ill to sit in a boat, and the next moment to mount a horse and ride a dozen miles. Smith's motives cannot now be ascertained, he never having explained them himself, either in the course of his trial, or in his Narrative; but he was probably alarmed at the firing upon the Vulture in the morning, and, as the vessel had resumed her original station, he was fearful it might be repeated, and thus endanger his personal safety, should he attempt to go on board. This is the only plausible way in which we can account for his resisting the strong solicitations of both Arnold and André, when he was sure of having the same protection as the night before. There is, after all, something mysterious in the affair; for, if this was the true and only cause of his reluctance, it was one, which might very properly have been urged, and would at least have relieved him from the subterfuge of the ague, which was too shallow to gain credit.

Any inquiry on this head would be fruitless. Indeed it is of little importance. It is enough to know, that, having no means of getting to the vessel, André was compelled to seek his way back by land. The safest route was supposed to be across the river and in the direction of White Plains. Smith agreed to attend him on the way, till he should be out of danger from the American posts. Thus far Arnold's passports would protect them.

All his entreaties being without avail, and having no other resort, André submitted to the necessity of his situation, and resolved to pursue the route by land. Arnold had prevailed upon him, in case he took this course, to exchange his military coat for a citizen's dress. It was feared, that, if he was discovered in the uniform of a British officer, he might be stopped, and perhaps meet with trouble. And here again Smith was made the dupe of Arnold's artifices. When he expressed surprise, that a man in a civil capacity, and on an errand of business, should come from New York in such a dress, Arnold told him that it was owing to the pride and vanity of Anderson, who wished to make a figure as a man of consequence, and had borrowed a coat from a military acquaintance. Upon this representation Smith gave one of his coats in exchange, which André put on, leaving his own behind. Thus clad, and covered as before with his dark greatcoat, which had a wide cape buttoned close in the neck, and the appearance of having been much worn, André was equipped for the journey.

A little before sunset he and Smith set off, accompanied by a negro servant belonging to the latter. They proceeded to King's Ferry, and crossed the river from Stony Point to Verplanck's Point. On their way to the Ferry, they met several persons who were known to Smith, and with whom he conversed, accosting them in a gay and jocular humor, and assuming an air of ease and unconcern. He even stopped at a sutler's tent near the Ferry, and contributed to the merriment of a party of loungers, by assisting them in drinking a bowl of punch. André said nothing, but walked his horse slowly along, and was waiting at the Ferry when his companion overtook him. Smith had tried, while on the road, to draw him into conversation about the taking of Stony Point the year before, and such other topics as he thought would interest him; but he was reserved and thoughtful, uttering brief replies, and showing no inclination to be interrogated, or to talk upon any subject.

It was in the dusk of the evening when they ascended from the Ferry, and passed through the works at Verplanck's Point. Smith rode up to Colonel Livingston's tent, at a short distance from the road, but André and the servant went along without stopping. Smith told Colonel Livingston, that he was going up the country, and took charge of two letters, one to General Arnold and the other to Governor Clinton, which he promised to deliver. He declined staying to supper, alleging as a reason that a gentleman had just rode along, who was waiting for him, and whose business was urgent. He then joined André on the way.

They met with no further interruption till between eight and nine o'clock at night, when they were hailed by the sentinel of a patrolling party. This was near Crompond, and about eight miles from Verplanck's Point. The sentinel ordered them to stop, and Smith dismounted, gave the bridle of his horse to his servant, walked forward, and inquired who commanded the party. He was answered "Captain Boyd," who, overhearing the conversation, immediately appeared. The captain was unusually inquisitive, and demanded of him who he was, where he belonged, and what was his business. Smith answered these questions promptly, adding that he had a pass from General Arnold, and desired not to be detained. The captain was not yet satisfied, but inquired how far he meant to go that night; to which he replied, as far as Major Strang's or Colonel Drake's; but this only increased the embarrassment, for the captain informed him, that Major Strang was not at home, and Colonel Drake had removed to another part of the country.

Captain Boyd then said, that he must see the passport, and, it being dark, they went to a house at a small distance to procure a light. André began to be a little alarmed, and advanced with reluctance towards the house, till he was encouraged by Smith, who assured him that Arnold's pass would certainly protect them. And so it proved; for the pass was expressed in positive terms, and there was no room to doubt its genuineness or its authority.

The captain was afterwards more bland in his manners, but the ardor of his curiosity was not diminished. He took Smith aside, and begged to be informed of the important business, which carried him down so near the enemy's lines, and induced him and his companion to travel so dangerous a road in the night. As an apology for this inquiry he manifested a good deal of concern for their safety, telling him that the Cow-boys had recently been out, and were believed then to be far up the country, and he advised him by all means not to proceed till morning. Smith prevaricated as well as he could, saying to Captain Boyd, that he and his fellow-traveller, whom he called Mr. Anderson, were employed by General Arnold to procure intelligence, that they expected to meet a person near White Plains for that purpose, and that it was necessary for them to go forward as expeditiously as possible.
