On the site of old Fort Hardy the Anglo-German army, October 17, grounded their arms at the command of their own officers, none of the American troops being present to witness this humiliation of the enemy. In the afternoon the captured troops crossed the Hudson, and, escorted by a company of light dragoons, were marched between the parallel lines of American soldiers, preceded by two officers, unfurling "the stars and stripes" just adopted by Congress. While this ceremony took place in the presence of Burgoyne and Gates, the former drew his sword and presented it to the latter, which being received was courteously returned, when both generals retired into Gates's tent.[728] While the prisoners, under guard of General Heath, were marching to Boston, Gates hurried to Albany to oppose any movement of Sir Henry Clinton; and Major Wilkinson was sent to Congress to communicate the joyful tidings of Burgoyne's surrender. Rejoicings were heard throughout the United States, and the successful general was so elated and his vanity so stimulated that he aspired to supplant Washington, as he had Schuyler. * * * * * A few criticisms upon the plan of the campaign of 1777, and the mode of conducting it, may be permitted. The British cabinet wisely decided upon the seizure of the Hudson as the most efficient way of breaking the power of the revolted colonies; but, in carrying out its design, it violated a fundamental maxim of war. No principle of strategy is better established than the superiority of _interior_ as against _exterior_ lines of operation of armies, as was so admirably illustrated in the "Seven Years' War." Frederic the Great, without any frontier barriers and open to attack on all sides, from his central position kept at bay France, Austria, Russia, Saxony, Sweden, and the Germanic body, whose united population was over twenty times as great as that of Prussia, including Silesia, a recently conquered province. In like manner, the Americans, in July, 1777, were within a great circle,—Schuyler on the upper Hudson, Putnam at the Highlands, and Washington in New Jersey, within supporting distance of each other; while the British armies were widely separated upon its vast circumference,—St. Leger moving to the upper Mohawk, Burgoyne from Canada, Clinton at New York, and Howe sailing to the Chesapeake. In the struggle for the Hudson, the two independent British armies—one in Canada and the other in New York—were expected to coöperate in order to attain a common object, while Burgoyne with the one was tied down by fixed orders, and Clinton with the other had no instructions as to the part he was expected to perform. Besides, their bases were separated by about four hundred miles of wild, hostile, and thinly populated country, rendering intercommunication so difficult that, of ten messengers sent out by different routes to Howe, not one returned to Burgoyne.
