Washington left New York City with John Jay, Alexander Hamilton (Secretary of Treasury), and Henry Knox (Secretary of War) as escorts, but it does not seem that every one of those companions made it all the way to Kingsbridge. “The house of one Hoyatt,” where Washington and “retinue” ate dinner, refers to Hyatt’s tavern on Marble Hill. Cole Thompson wrote about the tavern here. It appears on many Revolutionary era maps:
The tavern and outbuildings (stables, barn, etc.) are represented by the cluster of 5 dots just to the east of “Prince Charles’s Redoubt,” which was a small fort atop Marble Hill. Today that would be the area of Broadway between W. 225th and W. 228th Street. The hill was a peninsula in those days and that is the Spuyten Duyvil Creek snaking around it. The bridge on the north side (top) is the King’s Bridge and the bridge on the east side is the Free Bridge (aka Dyckman’s Bridge aka Farmer’s Bridge). On the return trip, Washington again stopped at Hyatt’s.
