As his school days drew to a close, it became necessary for Lee to determine his future calling. But the choice of a career, often so perplexing to young men, presented no difficulty to "Light Horse Harry's" son. He had apparently always intended to become a soldier and no other thought had seemingly ever occurred to any member of his family. Appointments to the United States Military Academy were far more a matter of favor than they are to-day, and young Lee, accompanied by Mrs. Lewis (better known as Nellie Custis, the belle of Mount Vernon and Washington's favorite grandchild), sought the assistance of General Andrew Jackson. Rough "Old Hickory" was not the easiest sort of person to approach with a request of any kind and, doubtless, his young visitor had grave misgivings as to the manner in which his application would be received. But Jackson, the hero of the battle of New Orleans in the War of 1812, only needed to be told that his caller was "Light Horse Harry's" son to proffer assistance; and in his nineteenth year, the boy left home for the first time in his life to enroll himself as a cadet at West Point. Very few young men enter that institution so well prepared for military life as was Lee, for he had been accustomed to responsibility and had thoroughly mastered the art of self-control many years before he stepped within its walls. He was neither a prig nor a "grind," but he regarded his cadetship as part of the life work which he had voluntarily chosen, and he had no inclination to let pleasure interfere with it. With his comrades he was companionable, entering into all their pastimes with zest and spirit, but he let it be understood, without much talk, that attention to duty was a principle with him and his serious purpose soon won respect. Rigid discipline was then, as it is to-day, strictly enforced at West Point, and demerits were freely inflicted upon cadets for even the slightest infraction of the rules. Indeed, the regulations were so severe that it was almost impossible for a cadet to avoid making at least a few slips at some time during his career. But Lee accomplished the impossible, for not once throughout his entire four years did he incur even a single demerit--a record that still remains practically unique in the history of West Point. This and his good scholarship won him high rank; first, as cadet officer of his class, and finally, as adjutant of the whole battalion, the most coveted honor of the Academy, from which he graduated in 1829, standing second in a class of forty-six.
