Some months later, Cherry Valley in New York suffered a similar visitation from the Indians, who now learned for the first time that a power had grown up in this country which could not only punish, but could do so with unprecedented vigor. The red men were so troublesome that Congress saw it would not do to defer giving them a much-needed lesson. The guilty Indians were the Iroquois in central New York. In 1779, General Sullivan led an expedition against them. He showed no mercy to those that had denied mercy to the helpless. Hundreds were killed, their houses burned, their fields laid waste, and the whole country made such a desert that many perished from starvation. THE CONTINENTAL CURRENCY. One of the "sinews of war" is money. It is impossible for any nation to carry on a war long without funds. The Americans were poor, but they issued paper promises to pay, which were known as Continental money. As the war progressed, and more money was needed, it was issued. In 1778, it took eight paper dollars to equal one of gold or silver. More was necessary and more was issued. Besides this, the paper and printing were of such poor quality that the British in New York made a great many counterfeits that were exchanged with the farmers in the vicinity. The value of the currency decreased until the time came when it was absolutely worthless. [Illustration: (Continental Currency)] When Clinton occupied New York and Washington was encamped on the Hudson above, there were many forays against each other. The design of the British commander was to force his way to the Highlands, seize the passes and gain full command of the Hudson. He had already secured Stony Point, and Washington formed a plan for retaking it, which was intrusted to the brilliant Anthony Wayne. In the middle of July, Wayne took command of four regiments of infantry, which marched twelve miles through the insufferably hot night, when they reached a point about a mile from the fort. Wayne went forward while his men were resting and made a careful reconnaissance. Rejoining his troops, he divided them into two columns, and, to prevent any mistake as to their identity, a piece of white paper was pinned to each hat. All the superfluous clothing was flung aside. He impressed upon his men that the bayonet alone was to be used, and, to prevent the discharge of a gun by some nervous soldier, he ordered his officers to cut down the first man who took his musket from his shoulder without the order to do so. The two divisions approaching from opposite sides were to attack the fort at the same moment. Before it was reached, the pickets discovered them and opened fire. The garrison was aroused, and, hurrying to their posts, cried out tauntingly: "Come on, you rebels! we're waiting for you!"
