The following two instances will illustrate his success. He once gave a mission for the soldiers of the garrison at La Rochelle, and moved by his words, the men wept, and cried aloud for the forgiveness of their sins. In the procession which terminated this mission, an officer walked at the head, barefooted and carrying a banner, and the soldiers, also barefooted, followed, carrying in one hand a crucifix, in the other a rosary, and singing hymns.
Grignion's extraordinary influence was especially apparent in the matter of the calvary at Pontchateau. When he announced his determination of building a monumental calvary on a neighbouring hill, the idea was enthusiastically received by the inhabitants. For fifteen months between two and four hundred peasants worked daily without recompense, and the task had just been completed, when the king commanded that the whole should be demolished, and the land restored to its former condition. The Jansenists had convinced the Governor of Brittany that a fortress capable of affording aid to persons in revolt was being erected, and for several months five hundred peasants, watched by a company of soldiers, were compelled to carry out the work of destruction. Father de Montfort was not disturbed on receiving this humiliating news, exclaiming only: "Blessed be God!"
This was by no means the only trial to which Grignion was subjected. It often happened that the Jansenists, irritated by his success, secure by their intrigues his banishment form the district, in which he was giving a mission. At La Rochelle some wretches put poison into his cup of broth, and, despite the antidote which he swallowed, his health was always impaired. On another occasion, some malefactors hid in a narrow street with the intention of assassinating him, but he had a presentiment of danger and escaped by going by another street. A year before his death, Father de Montfort founded two congregations — the Sisters of Wisdom, who were to devote themselves to hospital work and the. instruction of poor girls, and the Company of Mary (popularly known today as Montfort Missionaries), devoting themselves to priestly ministry and preaching. He had long cherished these projects but circumstances had hindered their execution, and, humanly speaking, the work appeared to have failed at his death, since these congregations numbered respectively only four sisters and two priests with a few brothers. But the blessed founder, who had on several occasions shown himself possessed of the gift of prophecy, knew that the tree would grow.
