It was now the great object of the British to get possession of New York. A powerful armament was daily expected. The tories had extensively entered into a conspiracy to unite with them. Extravagant reports were in circulation respecting their diabolical plans of assassination and plunder. The plot, infamous in all its aspects, was traced, by a committee of Congress, of which John Jay was chairman, distinctly to Governor Tryon, who, from his safe retreat on a British man-of-war, was acting through his agents. David Mathews, the tory mayor of the city, was deeply implicated in the plot. Mathews was residing at Flatbush. He was arrested, with many others. This threw the tories into the greatest dismay. Conscious of guilt, many fled into the woods. It was proved that Tryon had offered a bounty of five guineas to every one who would enlist in the service of the king, with the promise of one hundred acres of land for himself, one hundred for his wife, and fifty for each child.[124] On the 28th of June, four British ships-of-war appeared off the Hook. The next morning forty vessels were in sight. They came from Halifax, bringing about ten thousand troops. Most of them were soldiers who had been expelled from Boston. The alarm was great. The conspiracy had undefined limits. It was reported that it extended into the American camp; and that men were bribed to spike the guns of the batteries as soon as the ships approached. Soon other vessels arrived, swelling the number of ships-of-war and transports, in the harbor, to one hundred and thirty. They did not attempt to ascend the Hudson, but landed their troops on Staten Island. The heights were soon whitened with their tents. General Howe came to Staten Island in one of these ships. He wrote, to the British government: “There is great reason to expect a numerous body of the inhabitants to join the army from the province of York, the Jerseys, and Connecticut, who, in this time of universal oppression, only wait for opportunities to give proofs of their loyalty and zeal.” What is now called “The Park,” upon which the City Hall stands, was then a field, at some distance out of town. General Greene was crossing the field one day, when a company of American artillery were there on drill. Their commander was almost girlish, of fragile and graceful stature, but exercised wonderful powers of command and discipline. He seemed to be but about twenty years of age. It was Alexander Hamilton, whose renown subsequently filled the land, but whose heroic life was sullied with many a stain. He was a native of one of the West India Islands, and from his youth, was inspired with the intense desire to make for himself a name in the world.[125]
