September 15, 1776: The Revolutionary War is in full throttle. 5,000 British troops -- including some Hessian mercenary soldiers -- are poised to invade Manhattan from warships massed along the East River opposite Kip's Bay. The British invasion begins. Far outnumbered, George Washington and his Continental Army are no match for this show of force, and flee north to Turtle Bay and west to what would later be 42nd Street. The American forces are eventually driven off the island in November, fleeing to New Jersey. The British win the battle, but ultimately lose the war.
Two stained-glass panels near the entrance of Tudor Tower commemorate this battle, stating
