Ulysses Grant reported to his first assignment at Jefferson Barracks, St. Louis in April 1843. Years later, he wrote:
It did seem to me, in my early army days, that too many of the older officers, when they came to command posts, made it a study to think what orders they could publish to annoy their subordinates and render them uncomfortable. I noticed, however, a few years later, when the Mexican war broke out, that most of this class of officers discovered they were possessed of disabilities which entirely incapacitated them for active field service. They had the moral courage to proclaim it, too. They were right; but they did not always give their disease the right name.
Some things never change.
