When the students at the École had been about to publish an attack on Napoleon's ideas for the Grand Empire in 1804, Poisson had managed to stop them, not because he supported Napoleon's views but rather because he saw that the students would damage the École Polytechnique by their actions. Poisson's motives were not understood by Napoleon's administration, however, and they saw Poisson as a supporter which did his career no harm at all.
Kapag ang mga mag-aaral sa École had been tungkol sa na-publish ng isang atake sa Napoleon ng mga ideya para sa Grand Empire in 1804, Poisson had pinamamahalaang upang ihinto ang mga ito, dahil hindi siya suportado Napoleon's views kundi dahil siya nakita na ang mga mag-aaral ay École Polytechnique ang pinsala sa pamamagitan ng kanilang mga aksyon. Poisson's motives ay hindi naintindihan ni Napoleon ang pangangasiwa, gayunpaman, at sila ay nakakita ng Poisson bilang isang bata na kung saan ay kanyang karera walang pinsala sa lahat.
