"The old general, whose boast it was that he never slept but with one eye, was already on the alert. A circumstance had given him proof positive that Sir Henry was in New York, and had aroused his military ire," writes Washington Irving. This paragraph refers to one of Clinton's spies, who was captured while gathering information in Putnam's camp at Peekskill. When Clinton heard of it he sent a war-vessel up the Hudson with a flag of truce, claiming the man as one of his officers. This was Old Put's reply:

Headquarters, 7th August, 1777.

Edmund Palmer, an officer in the enemy's service, was taken as a spy lurking within our lines. He has been tried as a spy, condemned as a spy, and shall be executed as a spy; and the flag is ordered to depart immediately.

I have the honor to be, etc., etc.,

Israel Putnam.

The last week in September, Washington drew upon the patient commander in the Highlands for more soldiers, so that he had only eleven hundred men left with which to meet and withstand the British invasion of his territory, which began on the 5th of October. Putnam was fully cognizant of the situation, for he wrote to Governor Clinton, his coadjutor in the defense of the Highlands, on the 29th of September: "I have received intelligence on which I can fully depend that the enemy received a reenforcement at New York last Thursday of about 3,000 British and foreign troops; that General Clinton has called in guides who belong about Croton River; has ordered hard bread to be baked; that the troops are called from Paulus Hook to Kingsbridge; and the whole are now under marching orders. I think it highly probable that the designs of the enemy are against the posts of the Highlands, or of some parts of the counties of Westchester or Duchess. P.S.—The ships are drawn up in the river, and I believe nothing prevents them paying us an immediate visit but a contrary wind!"

Within a week the enemy were in force on the river near Putnam's position, and within ten days they had completely outmaneuvered both Putnam and Clinton, and had taken forts Montgomery and Clinton, their chief defenses, with great loss to the Americans. Clinton had made a feint on Tarrytown and Peekskill, and after this diversion, under cover of the river mist, landed troops on the west shore of the Hudson, and marched rapidly through ravines and dense woods to the rear of the two forts, which were carried by the bayonet, the defenders being taken by surprise.

The British had twice the number of men that Putnam commanded in this attack, and also the advantage of ships of war in the river, but it is thought that results would have been different from what they were had a despatch for reenforcements from Governor Clinton reached him. It was sent by a messenger who proved a traitor and carried it within the enemy's lines. As it was, however, the British have the credit of consummate strategy on this occasion, and poorly as he was equipped, Old Put was greatly mortified over the defeat. He had good occasion for writing to Washington, as he wrote on the 8th of October: "I have repeatedly informed your Excellency of the enemy's design against this post, but from some motive or other you always differed from me in opinion. As this conjecture of mine has for once proved right, I can not omit informing you that my real and sincere opinion is that they mean to join General Burgoyne with the utmost despatch."

Further proof of British intentions was afforded by the capture of a spy, who, on being arrested, was seen to swallow a silver bullet which, being recovered, was found to contain a message written on very thin paper and dated October 8th—the day before. This message read: "Here we are, and nothing between us and Gates. I sincerely hope this little success of ours will facilitate your operations." It was from Sir Henry Clinton to General Burgoyne, and showed conclusively that the former had set out to join with the latter. But events had so shaped in the north that poor Burgoyne was then past all aid, General Gates then having him at bay. Within a few days was fought the decisive battle that brought about Burgoyne's surrender, and when the news reached Sir Henry Clinton he immediately set about returning to New York, there being no longer any incentive for action in the Highlands. Putnam and Clinton, after blowing up their two vessels in the river, had effected their retreat to Fishkill, where they entrenched; but on learning of the British retreat they moved down to their former positions.

The saying that "troubles never come singly" proved true for General Putnam that month of October, 1777, for on the 14th he lost by death his faithful wife, who had been with him at headquarters. Washington wrote him, on being informed of the bereavement: "I am extremely sorry for the death of Mrs. Putnam, and sympathize with you upon the occasion. Remembering that all must die, and that she had lived to an honorable age, I hope you will bear the misfortune with that fortitude and complacency of mind that become a man and a Christian."
