Time at West Point
Beauregard proved his worthiness as a military leader early in his time being educated at West Point, which remains one of the most prestigious military academies. According to "Napoleon in Grey, he "stood among the five most distinguished cadets during his first three years, being fourth in 1835 and second in 1836 and 1837." Also noted in that book, was evidence of his famous charisma. It was stated that "when he spoke and when he acted, people thought of Paris and Napoleon and Austerlitz and French legions bursting from the St. Bernard Pass onto the plains of Italy." This type of charisma would be an advantage and an adversary in life.
Mexican-American War
Beauregard's time in the Mexican-American War was possibly the most revealing about his character. He inspired others with his willingness to speak out against superiors when he knew he was right, and with his dedication and long work schedule. As a Military Engineer, it was his job to locate viable places for gun batteries, and to assist in planning sieges. One of his biggest contributions was the sieging of Vera Cruz. Beauregard was tasked by General Winfield Scott to oversee the placement of the batteries which would bombard the city during the siege. However, Beauregard saw better locations for the gun placements. Going against direct orders, Beauregard delayed the construction of the batteries and requested that the locations he had chosen be used instead. Upon reviewing his objections, Scott agreed to let Beauregard move the batteries, which proved to be a massive success. This showed that not only was Beauregard a brilliant engineer, but he was not afraid to defy those in charge if he saw a better way to handle a situation. During the construction of these batteries, Beauregard's work schedule, "went on duty at 2 a.m, and off at 4 p.m, or started at 2 p.m. and quit at 4 a.m." This rigorous work schedule set the standard for others involved in the operation, pushing the other engineers to work just as hard.
