On Thursday, September 21, 1780, General Arnold met with André on the shores of the Hudson River and gave him documents and maps about the fortifications at West Point in anticipation of the British capture of that site. On Saturday, September 23, André was arrested as he rode towards British territory, the documents were discovered, and the plot was exposed. On Monday, September 25, Arnold received a note announcing André's capture and possession of treasonous papers and maps. That same morning, General George Washington was planning to meet Arnold at his home, two miles south of West Point. Arnold first dashed upstairs to Peggy, then fled, eventually reaching HMS "Vulture" on the Hudson River.
