After the War of 1812, Worth was the Commander of Cadets at West Point. During his time there, he was highly regarded by West Point that they put one of his most famous quotes in the Bugle Notes:
But an officer on duty knows no one -- to be partial is to dishonor both himself and the object of his ill-advised favor. What will be thought of him who exacts of his friends that which disgraces him? Look at him who winks at and overlooks offences in one, which he causes to be punished in another, and contrast him with the inflexible soldier who does his duty faithfully, notwithstanding it occasionally wars with his private feelings. The conduct of one will be venerated and emulated, the other detested as a satire upon soldiership and honor.A little after his time at West Point, he was promoted to the rank of Colonel and was sent to Florida to put an end to the Second Seminole War. After using his own tactics to squash the fighting, Worth was promoted to Brigadier Generally and even convinced the Secretary of State to allow the remaining Indians in the area to remain there. Much like before, Worth was also involved in the Mexican-American War in a number of battles that led to quite the fame he had become used to by now. Worth later died in 1849 due to cholera.
