and spent much time with the cadets. Lee's oldest son, George Washington Custis Lee, attended West Point during his tenure. Custis Lee graduated in 1854, first in his class. Lee was enormously relieved to receive a long-awaited promotion as second-in-command of the 2nd Cavalry Regiment in Texas in 1855. It meant leaving the Engineering Corps and its sequence of staff jobs for the combat command he truly wanted. He served under Colonel Albert Sidney Johnston at Camp Cooper, Texas; their mission was to protect settlers from attacks by the Apache and the Comanche. Late 1850s: Arlington plantation and the Custis slaves In 1857, his father-in-law George Washington Parke Custis died, creating a serious crisis when Lee took on the burden of executing the will. Custis's will encompassed vast landholdings and hundreds of slaves balanced against massive debts, and required Custis's former slaves "to be emancipated by my executors in such manner as to my executors may seem most expedient and proper, the said emancipation to be accomplished in not exceeding five years from the time of my decease."

Lee tried to hire an overseer to handle the plantation in his absence, writing to his cousin, "I wish to get an energetic honest farmer, who while he will be considerate & kind to the negroes, will be firm & make them do their duty." But Lee failed to find a man for the job, and had to take a two-year leave of absence from the army in order to run the plantation himself. Lee's more strict expectations and harsher punishments of the slaves on Arlington plantation nearly led to a slave revolt, since many of the slaves had been given to understand that they were to be made free as soon as Custis died, and protested angrily at the delay.

Reuben, Parks & Edward, in the beginning of the previous week, rebelled against my authority—refused to obey my orders, & said they were as free as I was, etc., etc.—I succeeded in capturing them & lodging them in jail. They resisted till overpowered & called upon the other people to rescue them." Less than two months after they were sent to the Alexandria jail, Lee decided
