It became necessary to turn the siege into a blockade. On the next day, vanquished by hunger, the scholars surrendered. They were promised a general amnesty. But, once in possession, the besiegers violated the treaty. "Then," adds Arnault, "I understood what politics was; I saw that it was not always in accord with the morality which we were so eloquently advised to respect as the equal of religion." And this was doubtless the reason why there were so many prefects of the Empire among the former pupils of Juilly! Father Petit was not the only Oratorist of whom Arnault handed down a good report. Father Viel, the translator of _Télémaque_ into Latin verse, showed so much justice and goodness in the college that the students always arranged to rebel while he was traveling, thus showing how much they respected him. Father Dotteville, the translator of Sallust and of Tacitus, built at Juilly a charming retreat where he cultivated literature and flowers. Father Prioleau, who taught philosophy, knew how to make all work lovable, even the study of Aristotle's Categories. Father Mandar, who later became superior of the college, was famous as a preacher--he was compared to Massillon--and as a poet--he was compared to Gresset. His lively muse, fertile in songs, rose even to descriptive poetry. Father Mandar wrote a poem called the Chartreuse; for he was sensitive to the beauties of nature and Jean Jacques had sought his company.... These remained, even to the end of their life, faithful to their vocation. Others failed in this, and owed their great celebrity neither to translations nor to the practice of oratorical virtues. Juilly was a nursery of Revolutionists and of Conventionals. One day--science was still honored in this Cartesian college--it was decided to give the pupils a scientific recreation. Under the direction of their professor of physics, they built a fire balloon of paper, upon which a prefect of studies who indulged in fugitive verse wrote this quatrain of his own composition: We have grown too old for soap bubbles; In changing balloons we change pleasures. If this carried our first homage to King Lotus, The winds would blow it to the goal of our desires. We do not know if the fire balloon came down in the park of Versailles. But we do know the names of the physicist and the poet of Juilly. The physicist was Father Fouché, and the poet was Father Billaud (Billaud-Varennes). Arnault remarks in this connection: "Ten years afterward, they showed themselves less gracious toward the monarch."
