It was now necessary that Clinton should be certified of the identity of General Arnold and his hidden correspondent, in order that he might make himself secure against a counterplot. A personal conference was proposed, and Arnold insisted that the officer sent to confer with him should be Adjutant-general Major Andre. * Clinton, on his part, had already fixed upon Andre as the proper person to hold the conference. It must be borne in mind that Andre did not seek the service, though, when engaged in it, he used his best endeavors, as in duty bound, to carry out its objects.
As money was the grand lure that made Arnold a traitor, he felt it necessary to have an understanding respecting the reward which he was to obtain. Under date of August 1780 30th, he wrote to Andre in the feigned hand and style alluded to, and said, referring to himself in the third person, "He is still of opinion that his first proposal is by no means unreasonable, and makes no doubt, when he has a conference with you, that you will close with it. He expects, when you meet, that you will be fully authorized from your house; that the risks and profits of the copartnership may be fully understood. A speculation of this kind might be easily made with ready money." Clinton understood this hint, and Andre was authorized to negotiate on that point.
Arnold's first plan was to have the interview at his own quarters in the Highlands, Andre to be represented as a person devoted to the American interest, and possessing ample means for procuring intelligence from the enemy. This was a safe ground for Arnold to proceed upon, for the employment of secret agents to procure intelligence was well known. ** He dispatched a letter to André informing him of this arrangement, and assuring him that if he could make his way safely to the American outposts above White Plains, he would find no obstructions thereafter. Colonel Sheldon was then in command of a detachment of cavalry stationed on the east side of the Hudson. His head-quarters, with a part of the detachment, was at Salem, and those of his lieutenant (Colonel Jameson) and of Major Tallmadge, with the remainder of the corps, were at North Castle. Arnold gave Sheldon notice that he expected a person from New York, with whom he would have an interview at the colonel's quarters, to make important arrangements for receiving early intelligence from the enemy. He requested Sheldon, in the event of the stranger's arrival, to send information of the fact to his quarters at the Robinson House. Arnold's plan was not entirely agreeable to Andre, for he was not disposed to go within the American lines and assume the odious character of a spy. He accordingly wrote the following letter to Colonel Sheldon, signed John Anderson, which, he knew, would be placed in Arnold's hands. It proposed a meeting at Dobbs's Ferry, upon the Neutral Ground. "I am told that my name is made known to you, and that I may hope your indulgence in permitting me to meet a friend near your outposts. I will endeavor to obtain permission to go out with a flag, which will be sent to Dobbs's Ferry on Monday next, the 11th instant, at twelve o'clock, when I shall be happy to meet September, 1780
Mr. G————. Should I not be allowed to go, the officer who is to command the escort—between whom and myself no distinction need be made—can speak in the affair.

** In this connection it may be mentioned, that when Arnold was about to proceed to the Highlands, he went to La Fayette, and requested him to give him the names of spies which the marquis had in his employ in-New York, suggesting that intelligence from them might often reach him more expeditiously by the way of West Point. La Fayette objected, saying that he was in honor bound not to reveal the names of spies to any person. The object which Arnold had in view became subsequently obvious.
