André went up the Hudson in the sloop-of-war Vulture. After the moon went down, and it was dark enough for such a deed, a boat came silently from the west shore near Haverstraw, and took back from the vessel a tall young man wrapped in a black cloak. Arnold met him on the bank and led him into a thicket of fir trees. There, like two ugly spirits of evil, they crouched in the darkness, and talked over the details of the dastardly deed.
Arnold, eager for British gold, haggled for a higher price. They plotted the utter ruin of the patriot cause, till, at the earliest streak of dawn, boom! boom! sounded some cannon! The traitor was frightened! One of our shore batteries was firing a few shots at the Vulture, so that she had to drop down stream a few miles. André therefore could not return directly to the Vulture, but was obliged to remain hidden all that day.
The plans had all been arranged. Clinton was to send up a fleet with soldiers to West Point, and Arnold was meanwhile to have removed most of his troops from the fort on some pretense, so that Clinton's force could easily capture it. Arnold gave André some papers to carry to Clinton, maps of the fort, with instructions how to approach and take it.
Sir Henry had warned André not to receive any papers from Arnold nor to put on any disguise. André for some reason did not obey these orders. He may have suspected that, after all, some trap was planned to deceive the British, and thought best to carry back papers in Arnold's own handwriting. At all events, it was a fatal mistake for poor André.
239. Capture of André.—- André wore long riding-boots. Between his stockings and the soles of his feet he put these papers. He took also a pass from Arnold to carry him through the guards. The Vulture having dropped down the river, André crossed over and set out on horseback to go back to New York on the east side.
All went well until he reached the vicinity of Tarrytown. At this time the region was infested with "cowboys" and "skinners," who under the pretense of keeping up a partisan warfare for their respective sides used to steal whatever they could find.
On this morning several men from the American army had been sent out to look after the "cowboys." As André rode along, three of this party sprang from the bushes, leveled their muskets at him, and ordered him to halt. They were young men, and their names were John Paulding, David Williams, and Isaac Van Wart. One of them happened to have on the coat of a Hessian soldier whom he had captured. This may have misled André and prompted him to make a blunder.
"Gentlemen," said André, "I hope you belong to our side."
"Which side?" asked Van Wart.
"The lower party," answered André. "I am a British officer on urgent duty, and hope you will not detain me."
