The conduct of Napoleon among his companions was that of a studious and reserved youth, addicting himself deeply to the means of improvement, and rather avoiding than seeking the usual temptations to dissipation of time. He had few friends, and no intimates; yet at different times, when he chose to exert it, he exhibited considerable influence over his fellow-students, and when there was any joint plan to be carried into effect, he was frequently chosen dictator of the little republic. In the time of winter, Bonaparte, upon one occasion, engaged his companions in constructing a fortress out of the snow, regularly defended by ditches and bastions, according to the rules of fortification. It was considered as displaying the great powers of the juvenile engineer in the way of his profession, and was attacked and defended by the students, who divided into parties for the purpose, until the battle became so keen that their superiors thought it proper to proclaim a truce. The young Bonaparte gave another instance of address and enterprise upon the following occasion. There was a fair held annually in the neighbourhood of Brienne, where the pupils of the Military School used to find a day's amusement; but on account of a quarrel betwixt them and the country people upon a former occasion, or for some such cause, the masters of the institution had directed that the students should not on the fair-day be permitted to go beyond their own precincts, which were surrounded with a wall. Under the direction of the young Corsican, however, the scholars had already laid a plot for securing their usual day's diversion. They had undermined the wall which encompassed their exercising ground, with so much skill and secrecy, that their operations remained entirely unknown till the morning of the fair, when a part of the boundary unexpectedly fell, and gave a free passage to the imprisoned students, of which they immediately took the advantage, by hurrying to the prohibited scene of amusement. But although on these, and perhaps other occasions, Bonaparte displayed some of the frolic temper of youth, mixed with the inventive genius and the talent for commanding others by which he was distinguished in after time, his life at school was in general that of a recluse and severe student, acquiring by his judgment, and treasuring in his memory, that wonderful process of almost unlimited combination, by means of which he was afterwards able to simplify the most difficult and complicated undertakings. His mathematical teacher was proud of the young islander, as the boast of his school, and his other scientific instructors had the same reason to be satisfied.
