Was it strange that Washington's heart was heavy? During the last week of August, the Continental army had been defeated in the battle of Long Island. A fourth of the army were on the sick list; a third were without tents. Winter was close at hand, and the men, mostly new recruits, were short of clothing, shoes, and blankets. Only fourteen thousand men were fit for duty, and they were scattered all the way from the Battery to Kingsbridge, a distance of a dozen miles or more. The British army, numbering about twenty-five thousand, lay encamped along the shores of New York Bay and the East River. The soldiers were veterans, and {51} they were led by veterans. A large fleet of war ships, lying at anchor, was ready to assist the land forces at a moment's notice. Scores of guard ships sailed to and fro, watching every movement of the patriot troops. To give up the city to the British without battle seemed a great pity. The effect upon the patriot cause in all the colonies would be bad. Still, there was no help for it. What was the use of fighting against such odds? Why run the risk of almost certain defeat? Washington always looked beyond the present, and he did not intend now to be shut up on Manhattan Island, perhaps to lose his entire army; so, with the main body, he moved north to Harlem Heights. Here he was soon informed by scouts that the British were getting ready to move at once. Whither, nobody could tell. Such was the state of affairs that led Washington to call his chief officers to the Murray mansion, on that September afternoon. Of course they talked over the situation long and calmly. After all, the main question was, What shall be done? Among other things, it was thought best to find the right sort of man, and send him in disguise into the British camp on Long Island, to find out just where the enemy were planning to attack. "Upon this, gentlemen," said Washington, "depends at this time the fate of our army." The commander in chief sent for Colonel Knowlton, the hero of the rail fence at Bunker Hill. {52} "I want you to find for me in your regiment or in some other," he said, "some young officer to go at once into the British camp, to discover what is going on. The man must have a quick eye, a cool head, and nerves of steel. I wish him to make notes of the position of the enemy, draw plans of the forts, and listen to the talk of the officers. Can you find such a man for me this very afternoon?" "I will do my best, General Washington," said the colonel, as he took leave to go to his regiment. On arriving at his quarters that afternoon, Knowlton called together a number of officers. He briefly told them what Washington wanted, and asked for volunteers. There was a long pause, amid deep surprise. These soldiers were willing to serve their country; but to play the spy, the hated spy, was too much even for Washington to ask.
