The Long and Storied History of Glenclyffe & The Garrison Institute 18th Century THE AMERICAN REVOLUTION Skirmishes for possession of West Point military academy (the building across the Hudson river) were fought on and around the land where the Garrison Institute now stands. Hessian mercenaries (of the British) were held in a prison camp on the grounds, and Sugar Loaf Mountain (directly across Route 9D to the east and formerly part of the estate) housed a military post armed with cannons. BENEDICT ARNOLD’S ESCAPE Below Sugar Loaf Mountain lays the Beverly Robinson House, Benedict Arnold’s headquarters while commander of West Point. While living there he conspired to commit treason against the Patriots by giving West Point defense plans to the British Major John Andre. General Washington had been coming to plan strategy with Benedict Arnold but before he arrived Patriot soldiers captured British Major John Andre. Benedict Arnold, knowing his treasonous deeds were about to be discovered mounted a horse and fled to the British ship, the HMS Vulture. Shortly after General Washington interviewed Major Andre in the Beverly Robinson house, Benedict Arnold’s treason was revealed, and Major Andre was executed.
19th Century THE FISH FAMILY 1861- Hamilton Fish (who had served as New York Governor and later US Senator and who would go on to be Secretary of State under President Grant), purchased a large plot of land in Garrison, New York and constructed a large imposing estate at a cost of $30,000 for him and his family. The home, (the abandoned mansion south of the Garrison Institute) which he named “Glenclyffe”, was considerably large for $30,000 and had 5 bedrooms, 6 bathrooms, 3 servant’s rooms, a library, drawing room, dining room, billiard room, den, morning room and a boudoir. The property had a large green house, stables, expansive gardens, gate house and spectacular views of the Hudson. Here Hamilton Fish entertained many foreign diplomats and U.S. notables. President Grant, himself, was a visitor and planted a tree that still stands in front of the Fish mansion. 1
