Kips Bay and the Disappearance of History

So here we are in New York City, on the island of Manhattan, on Second Avenue looking across the intersection of 33rd and north towards 34th Street--as best as I can determine from my readings, the site of the actual landing of the British at Kip's Bay on September 15, 1776.  Landfill has moved Manhattan to the east; Kip's Farm itself was supposedly at 35th and Second, hence the name of the area.  If there is any signage of this momentous landing--the "D-Day" of 1776 with massive bombardment of the American forces and a well-coordinated amphibious landing by the British--I could not find any.  There are other such signs in New York at various Revolutionary spots; too bad that this, the actual physical invasion by a foreign force in New York, not seen again until September 11, 2001, is otherwise unmarked.  Following the rapid retreat of the overwhelmed American forces, Howe proceeded in leisurely pace up Manhattan, while the Americans re-established their position to the north.
