As for Washington, the successful retreat had not in the least relieved him from care or anxiety. He had escaped one trap: it was of the utmost consequence now to see that he did not fall into another. What he feared most was a sudden move upon his rear in Westchester County, for in that case he would be hopelessly hemmed in on Manhattan Island. "The enemy," continued Trumbull on the 1st, "are drawing their men to the eastward on Long Island, as if they intended to throw a strong party over on this island, near Hell Gate, so as to get on the back of the city. We are preparing to meet them." Haslet wrote August 31st: "I expect every moment orders to march off to Kingsbridge to prevent the enemy crossing the East River and confining us on another nook.... If they can coop us up in N. York by intrenching from river to river, horrid will be the consequences from their command of the rivers." General Heath pressed the matter of watching the Westchester coast, and Washington, concurring with him "as to the probability of the enemy's endeavoring to land their forces at Hunt's Point," above Hell Gate, wrote him on the 31st: "In order to prevent such an attempt from being carried into execution I have sent up General Mifflin with the troops he brought from your quarters, strengthened by reinforcements. With this assistance I hope you will be able to defeat their intentions. I beg you will exert yourself to the utmost of your abilities on this momentous occasion." Several days passing without any demonstration by the enemy, Washington's suspense was only protracted, and on September 5th he wrote again to Heath as follows: "As everything in a manner depends upon obtaining intelligence of the enemy's motions, I do most earnestly entreat you and General Clinton to exert yourselves to accomplish this most desirable end. Leave no stone unturned, nor do not stick at expense to bring this to pass, as I never was more uneasy than on account of my want of knowledge on this score. "Keep, besides this precaution, constant lookouts (with good glasses) on some commanding heights that look well on to the other shore (and especially into the bays, where boats can be concealed), that they may observe, more particularly in the evening, if there be any uncommon movements. Much will depend upon early intelligence, and meeting the enemy before they can intrench. I should much approve of small harassing parties, stealing, as it were, over in the night, as they might keep the enemy alarmed, and more than probably bring off a prisoner, from whom some valuable intelligence may be obtained."[173] [Footnote 173: "The Heath Correspondence," Mass.
