It was but a few days, however, before he was ordered to headquarters and assigned to duty as Secretary to the Commander-in-Chief, an event which marked the permanent termination of his medical practice. The relations which henceforth existed between the stern and reserved Washington and his brilliant and tactful young aid were cordial in the extreme. This happy relationship continued until 1780, when he was relieved from duty with the Commander-in-Chief and assigned nominally as aide-decamp but really as guide, philosopher and friend to the youthful and enthusiastic [[Marquis de Lafayette]], who had been commissioned as a Major General in the American establishment. In May 1781, Dr. McHenry was commissioned as Major to date from the preceding October. | It was but a few days, however, before he was ordered to headquarters and assigned to duty as Secretary to the Commander-in-Chief, an event which marked the permanent termination of his medical practice.
