The war against the Jesuits in France was approaching its crisis, and the ordinance which deprived them of the liberty of teaching and shut up all their colleges was promulgated just about the time of Father de Ravignan's ordination. {115} Cut off from the privilege of secular instruction, the society resolved to devote itself more zealously than ever to the theological training of its own members. Father de Ravignan was assigned a chair of theology at Saint Acheul, near Amiens; for he was not only a thorough scholar, but he possessed a rare talent for teaching, and according to the testimony of his pupil, Father Rubillon, fully realized "the idea of a professor of theology such as is depicted by St. Ignatius." The poor fathers, however, were not to be left here in peace. In 1829, they received notice to suspend their classes; but Father de Ravignan hastened to Paris, saw the Minister of Public Instruction, and caused the order to be set aside. The next year came the revolution of July. Late in the evening of the 29th, a mob, led by an expelled pupil, attacked the college, burst in gates, and with cries for "The King and the Charter!" "The Emperor!" "Liberty!" and "Down with the priests!" and "Death to the Jesuits!" proceeded to sack the building. While some of the fathers took refuge in the chapel, and others, expecting death, were busy hearing one another's confessions, Father de Ravignan went upon a balcony, and tried to make himself heard by the rioters. He persisted until a stone struck him on the temple, and he was led away bleeding. To what lengths the fury of the mob would have gone it is impossible to say; but fortunately, in the course of their devastation they stumbled into the wine-cellar, and all got drunk. The arrival of a troop of cavalry dispersed the reeling crowd in the twinkling of an eye, and the Jesuits were left to mourn over the ruins. The next day it seemed certain that the attack would be renewed. The college was deserted, and its inmates scattered in different directions, Father de Ravignan being sent to Brigue in Switzerland to resume his courses of theological instruction. It was not until the close of 1834 that he came back to France. Then we find him once more at Saint Acheul, where, since classes were prohibited, a house had been opened for fathers in their third year of probation. Three years later, he was appointed superior of a new house at Bordeaux. There he remained until 1842.
