Washington was at headquarters when Lafayette reached Philadelphia, but he was daily expected in the city. The introduction of the youthful stranger to the man on whom his career depended was therefore delayed a few days. It took place in a manner peculiarly marked with the circumspection of Washington, at a dinner party, where Lafayette was one among several guests of consideration. Washington was not uninformed of the circumstances connected with his arrival in the country. He knew what benefit it promised the cause if his character and talents were adapted to the cause he had so boldly struck out, and he knew also how much it was to be feared that the very qualities which had prompted him to embark in it, would make him a useless and even a dangerous auxiliary. We may well suppose that the piercing eye of the Father of his Country was not idle during the repast. But that searching glance, before which pretense or fraud never stood undetected, was completely satisfied. When they were about to separate, Washington took Lafayette aside, spoke to him with kindness, paid a just tribute to the noble spirit which he had shown, and the sacrifices he had made in the American cause, invited him to make the headquarters of the army his home, and to regard himself at all times as one of the family of the Commander-in-Chief. Such was the reception given to Lafayette by the most sagacious and observant of men, and the personal acquaintance thus commenced ripened into an intimacy, a confidence, and an affection without bounds, and never for one moment interrupted. If there lived a man whom Washington loved it was Lafayette. The proofs of this are not wanted by those who have read the history of the Revolution, but the private correspondence of these two great men, hitherto unpublished, discloses the full extent of the mutual regard and affection which united them. It not only shows that Washington entertained the highest opinion of the military talent, the personal probity, and the general prudence and energy of Lafayette, but that he regarded him with the tenderness of a father, and found in the affection which Lafayette bore to him in return one of the greatest comforts and blessings of his own life. Whenever the correspondence of Washington and Lafayette shall be published, the publication will do what perhaps nothing else can--raise them both in the esteem and admiration of mankind. Our readers will pardon this somewhat lengthened quotation respecting the bosom friend of Washington. We now return to our narrative of events. Late in the month of August (1777), Washington was relieved from his suspense in regard to the movements of Howe. He received intelligence that the British fleet had sailed up Chesapeake Bay, and that he was landing his army at the head of Elk river, now Elkton. It was at length clearly apparent that his object was the capture of Philadelphia.
