Willard Sterne Randall, who visits today, writes of Alexander Hamilton's efforts to defend Manhattan against the British navy in the January 2003 issue of Smithsonian Magazine.
"On August 8, Hamilton tore open orders from Washington: his company was to be on round-the-clock alert against an imminent invasion of Manhattan. “The movements of the enemy and intelligence by deserters give the utmost reason to believe that the great struggle in which we are contending for everything dear to us and our posterity, is near at hand,” Washington wrote.
"But early on the morning of August 27, 1776, Hamilton watched, helpless, as the British ferried 22,000 troops from Staten Island, not to Manhattan at all, but to the village of Brooklyn, on Long Island. Marching quickly inland from a British beachhead that stretched from Flatbush to Gravesend, they met little resistance. Of the 10,000 American troops on Long Island, only 2,750 were in Brooklyn, in four makeshift forts spread over four miles. At Flatbush, on the American east flank, Lord Charles Cornwallis quickly captured a mounted patrol of five young militia officers, including Hamilton’s college roommate, Robert Troup, enabling 10,000 redcoats to march stealthily behind the Americans. Cut off by an 80-yard-wide swamp, 312 Americans died in the ensuing rout; another 1,100 were wounded or captured. By rowboat, barge, sloop, skiff and canoe in a howling northeaster, a regiment of New England fishermen transported the survivors across the East River to Manhattan. More.
