Before he had been in America long André, by reason of his courage and intelligence, rose to the position of aide-de-camp to Sir Henry Clinton, commander-in-chief of the British forces. It was at this juncture that Benedict Arnold, smarting under supposed wrongs, made a proposition to the British to betray to them the post at West Point, of which he was in command. It was regarded as the key to the American position and General Clinton designated Major André as the man to conduct the negotiations with the traitor Arnold. The importance of this position was equaled by its danger. The conspiracy between Arnold and André had been carried on by means of correspondence for quite a while. They wrote under fictitious names, and naturally the greatest secrecy was observed. But finally the time came when it was necessary to hold a personal meeting in order to bring the treason to a head. Major André at that time held the position of adjutant general in the British army, and it was at Arnold’s request that he was detailed to meet the traitorous general for the purpose of settling all the details. On the 20th of September, 1780, André went on board the British sloop of war _Vulture_ with Colonel Beverly Robinson, and proceeded up the Hudson with a view of holding an interview with Arnold. There is a strong feeling, or at least circumstantial evidence, which indicates that Robinson was partially responsible for bringing Arnold to the state of mind where he was willing to sacrifice his country in order to satisfy his own wounded vanity. At all events, they made the trip together and on the night of the 21st a boat was sent by Arnold to the _Vulture_ which brought André to the shore about six miles below Stony Point. In a secluded spot and after midnight the conspirators met and prepared the plans by which the American cause was to be betrayed. Daylight appeared and still the conference went on. It was suggested that it would be desirable to have breakfast, and at Arnold’s invitation André consented to accompany him to the house of Joshua Smith, which was about two miles below the meeting place. They sat there for a long time and presently the booming of cannon was heard and they saw that the _Vulture_ had weighed anchor and was proceeding down the river. This was due to the fact that Colonel Livingston of the American army thought that she was too near the American outposts, and with characteristic promptness he brought cannon to bear on the vessel and compelled her to descend the river.
