For several months, he continued to serve in this capacity. His zeal and services were early appreciated by Congress; and in July, 1777, he was created a Major-General. But he did not, at once, act under that commission. In the battle of Brandywine, in September of the same year, although he distinguished himself by his activity and undaunted bravery, it does not appear that he acted as Major-General. He received a wound in his leg, in this engagement, and his services were highly applauded. He remained in the field till the close of the battle, inspiring the men by his presence and active courage. The wound was severe and required attention; but before it was entirely healed, he joined the army again under WASHINGTON. In November, at the head of some Jersey militia, he attacked a body of 300 Hessians and defeated them. General GREENE was engaged in the same affair, a part of the time; and said of young LAFAYETTE, "that he seemed to search for danger." Soon after this period, he had command of a division in the Continental army; and frequently was appointed the chief officer in separate departments of great importance and responsibility. General WASHINGTON became greatly attached to him. He was an intelligent judge of character; and was never known to bestow his confidence upon those who were not worthy of it. He was so distinguished by the regard of the Commander in Chief, that it became usual to call him "his adopted son." WASHINGTON loved him for his goodness, and honored him for his bravery and military talents. In the early part of 1778, when it was proposed to make an attack upon Canada, and to endeavor to connect it with the thirteen United States, Gen. LAFAYETTE was appointed to command the troops collecting for that purpose at Albany. This plan originated in Congress, and was said to be much favored by the French Ambassador; but WASHINGTON ever doubted the propriety, or the feasibility of the scheme, and eventually gave his opinion decidedly against it; and it was not prosecuted. It was at this time, probably, that Brigadier General STARK took the oath of fidelity to the American Congress and of renunciation to the king and government of Great Britain, which had then been recently required, before General LAFAYETTE; and which was administered by the commanding officer in each separate Department. The original certificate of this oath is said now to be in existence. It is a singular fact, that a native American took this oath before a foreigner: or perhaps even then, General LAFAYETTE had been declared by Congress to be entitled to all the rights of a citizen of the United States.
