WASHINGTON'S HEAD-QUARTERS. RICHMOND HILL HOUSE, 1776.

       Vol. II.

      A committee of the New York Congress traced the plot up to Governor Tryon, who, from his safe retreat on shipboard, acted through agents on shore. The most important of these was David Matthews, the tory mayor of the city. He was accused of disbursing money to enlist men, purchase arms, and corrupt the soldiery. Washington was authorized and requested by the committee to cause the mayor to be apprehended, and all his papers secured. Matthews was at that time residing at Flatbush on Long Island, at no great distance from General Greene's encampment. Washington transmitted the warrant of the committee to the general on the 21st, with directions that it should "be executed with precision, and exactly by one o'clock of the ensuing morning, by a careful officer." Precisely at the hour of one, a detachment from Greene's brigade surrounded the house of the mayor, and secured his person; but no papers were found, though diligent search was made.

      Numerous other arrests took place, and among the number, some of Washington's body-guard. A great dismay fell upon the tories. Some of those on Long Island who had proceeded to arm themselves, finding the plot discovered, sought refuge in woods and morasses. Washington directed that those arrested, who belonged to the army, should be tried by a court-martial, and the rest handed over to the secular power.

      According to statements made before the committee, five guineas bounty was offered by Governor Tryon to each man who should enter the king's service; with a promise of two hundred acres of land for himself, one hundred for his wife, and fifty for each child. The men thus recruited were to act on shore, in co-operation with the king's troops when they came. Corbie's tavern, near Washington's quarters, was a kind of rendezvous of the conspirators. From this house a correspondence was kept up with Governor Tryon on shipboard, through a mulatto. At this tavern it was supposed Washington's body-guards were tampered with. Thomas Hickey, one of the guards, was said not only to be enlisted, but to have aided in corrupting his comrades.

      Much of the evidence given was of a dubious kind. It was certain that persons had secretly been enlisted and sworn to hostile operations, but Washington did not think that any regular plan had been digested by the conspirators. According to the mayor's admission before the committee, he had been cognizant of attempts to enlist tories and corrupt Washington's guards, though he declared that he had discountenanced them. He, with a number of others, were detained in prison to await a trial. Thomas Hickey, the individual of Washington's guard, was tried before a court-martial. He was an Irishman, and had been a deserter from the British army. The court-martial found him guilty of mutiny and sedition, and treacherous correspondence with the enemy, and sentenced him to be hanged. The sentence was approved by Washington, and was carried promptly into effect June 28th.

      While the city was still brooding over this event, four ships-of-war, portentous visitants, appeared off the Hook, stood quietly in at the Narrows, and dropped anchor in the bay. On the 29th of June an express from the look-out on Staten Island, announced that forty sail were in sight. They were, in fact, ships from Halifax, bringing between nine and ten thousand of the troops recently expelled from Boston; together with six transports filled with Highland troops, which had joined the fleet at sea. At sight of this formidable armament standing into the harbor, Washington instantly sent notice of its arrival to Colonel James Clinton, who had command of the posts in the Highlands, and urged all possible preparations to give the enemy a warm reception should they push their frigates up the river. Other arrivals swelled the number of ships in the bay of New York to one hundred and thirty men-of-war and transports. They made no movement to ascend the Hudson, but anchored off Staten Island, where they landed their troops, and the hill sides were soon whitened with their tents.

      Washington beheld the gathering storm with an anxious eye, aware that General Howe only awaited the arrival of his brother, the admiral, to commence hostile operations. He wrote to the President of Congress, urging a call on the Massachusetts government for its quota of continental troops; and the formation of a flying camp of ten thousand men, to be stationed in the Jerseys as a central force, ready to act in any direction as circumstances might require. On the 2d of July he issued a general order, calling upon the troops to prepare for a momentous conflict which was to decide their liberties and fortunes. Those who should signalize themselves by acts of bravery would be noticed and rewarded; those who proved craven would be exposed and punished.

About this time, we have the first appearance in the military ranks of the Revolution of one destined to take an active and distinguished part in public affairs; and to leave the impress of his genius on the institutions of the country. As General Greene one day, on his way to Washington's head-quarters, was passing through a field—then on the outskirts of the city, now in the heart of its busiest quarter, and known as "the Park,"—he paused to notice a provincial company of artillery, and was struck with its able performances, and with the tact and talent of its commander. He was a mere youth, apparently about twenty years of age; small in person and stature, but remarkable for his alert and manly bearing. It was Alexander Hamilton.¹

      Greene was an able tactician, and quick to appreciate any display of military science; a little conversation sufficed to convince him that the youth before him had a mind of no ordinary grasp and quickness. He invited him to his quarters, and from that time cultivated his friendship. Further acquaintance heightened the general's opinion of his extraordinary merits, and he took an early occasion to introduce him to the commander-in-chief, by whom we shall soon find him properly appreciated.

      A valuable accession to the army, at this anxious time, was Washington's neighbor, and former companion in arms, Hugh Mercer. His military spirit was alert as ever; the talent he had shown in organizing the Virginia militia, and his zeal and efficiency as a member of the committee of safety, had been properly appreciated by Congress, and on the 5th of June he had received the commission of brigadier-general. He was greeted by Washington with the right hand of fellowship. The flying camp was about forming. Washington had the nomination of some continental officer to the command. He gave it to Mercer, and sent him over to Paulus Hook, in the Jerseys, to make arrangements for the militia as they should come in; recommending him to Brigadier-general William Livingston, as an officer on whose experience and judgment great confidence might be reposed. Livingston was a
