Men of the highest rating at West Point may choose whatever arm of the service they prefer, and Lee, selecting the Engineer Corps, was appointed a second lieutenant and assigned to fortification work at Hampton Roads, in his twenty-second year. The work there was not hard but it was dull. There was absolutely no opportunity to distinguish oneself in any way, and time hung heavy on most of the officers' hands. But Lee was in his native state and not far from his home, where he spent most of his spare time until his mother died. Camp and garrison life had very little charm for him, but he was socially inclined and, renewing his acquaintance with his boyhood friends, he was soon in demand at all the dances and country houses at which the young people of the neighborhood assembled. Among the many homes that welcomed him at this time was that of Mr. George Washington Parke Custis (Washington's adopted grandson), whose beautiful estate known as "Arlington" lay within a short distance of Alexandria, where Lee had lived for many years. Here he had, during his school days, met the daughter of the house and, their boy-and-girl friendship culminating in an engagement shortly after his return from West Point, he and Mary Custis were married in his twenty-fifth year. Lee thus became related by marriage to Washington, and another link was formed in the strange chain of circumstances which unite their careers. A more ideal marriage than that of these two young people cannot be imagined. Simple in their tastes and of home-loving dispositions, they would have been well content to settle down quietly to country life in their beloved Virginia, surrounded by their family and friends. But the duties of an army officer did not admit of this, and after a few years' service as assistant to the chief engineer of the army in Washington, Lee was ordered to take charge of the improvements of the Mississippi River at St. Louis, where, in the face of violent opposition from the inhabitants, he performed such valuable service that in 1839 he was offered the position of instructor at West Point. This, however, he declined, and in 1842 he was entrusted with the task of improving the defenses of New York harbor and moved with his family to Fort Hamilton, where he remained for several years. Meanwhile, he had been successively promoted to a first lieutenancy and a captaincy, and in his thirty-eighth year he was appointed one of the visitors to West Point, whose duty it was to inspect the Academy and report at stated intervals on its condition. This appointment, insignificant in itself, is notable because it marks the point at which the trails of Grant and Lee first approach each other, for at the time that Captain Lee was serving as an official visitor, Ulysses Grant was attempting to secure an assistant professorship at West Point.
