It was at this period that Hale planned an attack, made by members of his own company, to set fire to the frigate Phoenix. The frigate was saved, but one of her tenders and four cannons and six swivels were taken. The men received the thanks, praises, and rewards of Washington, and the frigate, with her companions, not caring to risk such attacks again, retired to the Narrows. Soon after this little brush with the enemy, Colonel Knowlton, of one of the Connecticut regiments, organized a special corps, which was known as Knowlton's Rangers. On the rolls of their own regiments the officers and men are spoken of as "detached on command." They received their orders direct from Washington and Putnam, and were kept close in front of the enemy, watching his movements from the American line in Harlem. It was in this service, on September 15th, that Knowlton's Rangers, with three Virginia companies, drove the English troops from their position in an open fight. It was a spirited action, which was a real victory for the attacking force. Knowlton and Leitch, the leaders, were both killed. In his general orders Washington spoke of Knowlton as a gallant and brave officer who would have been an honor to any country. But Hale, alas! was not fighting at Knowlton's side. He was indeed "detached for special service." Washington had been driven up the island of New York, and was holding his place with the utmost difficulty. On September 6th he wrote, "We have not been able to obtain the least information as to the enemy's plans." In sheer despair at the need of better information than the Tories of New York City would give him, the great commander consulted his council, and at their direction summoned Knowlton to ask for some volunteer of intelligence, who would find his way into the English lines, and bring back some tidings that could be relied upon. Knowlton summoned a number of officers, and stated to them the wishes of their great chief. The appeal was received with dead silence. It is said that Knowlton personally addressed a non-commissioned officer, a Frenchman, who was an old soldier. He did so only to receive the natural reply, "I am willing to be shot, but not to be hung." Knowlton felt that he must report his failure to Washington. But Nathan Hale, his youngest captain, broke the silence. "I will undertake it," he said. He had come late to the meeting. He was pale from recent sickness. But he saw an opportunity to serve, and he did the duty which came next his hand.
