“Let us march immediately,” he cried with all of the passionate ardor of youth, “and let us never lay down our arms until we have obtained our independence.”

As a proof of both his consistency and his patriotism, Hale immediately enrolled himself as a volunteer. The following morning he bade good-by to his pupils and departed for Cambridge. Before long he had been formally enlisted as a lieutenant of a company in a regiment commanded by Colonel Charles Webb, and late in September of that year marched with his regiment to Cambridge and participated in the siege of Boston. Within three months he had been commissioned as a captain because of vigilance and bravery. The British were driven from Boston in the spring of the following year, and soon after that the Americans proceeded to New York. His earnestness in the cause was proven when he surrendered his own pay to his men in the endeavor to have them prolong their term of service, which had already expired.

Even at this early stage of his military career he covered himself with glory by performing what proved to be one of the most daring feats of the Revolution. A British sloop laden with provisions was anchored in the East River under the protection of the guns of a man-of-war called the Asia. Hale went to General Heath and obtained permission to attempt the capture of the supply vessel. With a few dozen picked men as resolute as himself, he embarked in a small boat at midnight and reached the side of the sloop unobserved by the sentinel. The young New Englander followed by his men sprang aboard the vessel, secured the sentinel, confined the crew below the hatches, raised the boat’s anchor and took her into the wharf just at the dawn of day. It was a dashing adventure and it was successful. He was the hero of the hour, especially among his fellow Americans, when the supplies were distributed among them. For many months after this he continued the routine work of a captain in the Revolutionary Army, and it was not until the 7th of September that he was called upon to take part in the thrilling exploit which was to end in such a disastrous and tragic manner. Washington had called a council of war to decide whether he should defend or abandon New York. He had already asked Congress this important question and he was answered by a resolution that in case he should find it necessary to quit New York he should have special care taken that no damage be done to the city. As a result of this he resolved to remain and defend the city.

General Washington had at this time made his headquarters at the house of Robert Murray. The position of his army was exceedingly perilous, ships of war having already passed up the East River. Scouts reported great activity among the British troops, but they were unable, after great efforts, to gain any intelligent idea of the intentions of the enemy. Yet Washington knew that it was most essential that he should have this information. He wrote to General Heath, then staying at Kings Bridge.

“As everything in a manner depends upon intelligence of the enemy’s motions, I do most earnestly entreat you and General Clinton to exert yourselves to accomplish this most desirable thing. Leave no stone unturned nor do not stick at expense to bring this to pass, as I was never more uneasy than on account of my want of knowledge on this score. Keep a constant lookout with good glasses on some commanding heights that look well on to the other shore.”

What Washington desired to know more than anything else was whether the British would make a direct attack upon the city, and if they did whether they intended to land upon the island above the city or Morrisania, beyond the Harlem River. The general in his perplexity called another council of war at Murray’s. At this conference it was resolved to send some courageous and competent person in disguise into the British camps on Long Island. The person needed was one skilled in military and scientific knowledge and a good draftsman—in short a man on whose judgment and fidelity they could absolutely depend. In this emergency Washington sent for Lieutenant Colonel Noulton and told him just what he wanted. In response Noulton summoned a number of officers to a conference at his quarters and in the name of the commander-in-chief called for volunteers. They were taken by surprise. There was a general reluctance to engage in the work of a spy. For a time it looked as if it would be impossible to obtain a man for the service, but at the last moment a young soldier who had been ill entered the room and learning the nature of the request called out:

“I will undertake the work.”

It was Captain Nathan Hale. Everybody was amazed, not the least among them being Lieutenant Colonel Noulton. Some of the others, who knew and loved Hale, privately endeavored to persuade him to reconsider his decision. They pointed out his hopes for the future and explained the ignominy and death to which he might be exposed. One of his dearest friends, William Hull, who was afterwards a general in the War of 1812, and who was a member of his company and had been his classmate at college, was especially fervid in trying to turn him from the perilous task, but Hale had made up his mind and would not change it. He said with great warmth:

“Gentlemen, I am satisfied that I owe to my country the accomplishment of an object so important and so much desired by the commander of her armies, and I know of no mode of obtaining the information except by assuming a disguise and passing into the enemy’s camp. I am fully sensible of the consequences of discovery and capture in such circumstances, but for a year I have been attached to the army and have not rendered any material service, while receiving a compensation for which I made no return. Yet I am not influenced by any expectation of promotion or pecuniary reward. I wish to be useful; and every kind of service necessary for the public good becomes honorable by being necessary. If the exigencies of my country demand a peculiar service its claims to the performance of that service are imperious.”

These words, thrilling with their patriotism, silenced the objections of his fellow soldiers. That very afternoon in company with Noulton he appeared before Washington and received instructions concerning his mission. He was provided with the necessary authority and also given a general order to the owners of all American vessels to convey him to any point on Long Island which he might designate.
