Early in the fifteenth century Abbot Jolivet surrounded the town with fortifications. The English, at this time invading France, besieged Mont Saint-Michel, but were repulsed by the brave d’Estouteville and his companions-in-arms, one hundred and twenty-nine in all, who successfully defended the post entrusted to them when the greater part of France had submitted to the conquerors. During the religious wars Mont St. Michel was several times attacked by the Protestants. On the Feast of St. Mary Magdalen, July 22, 1577, a number of them, habited as pilgrims and concealing their weapons, were admitted without suspicion into the church, where, after hearing several Masses with great show of devotion, they divided into small groups, and, with an air of calm indifference, occupied different parts of the buildings, until, secure of their position, they murdered such of the guards as did not escape by flight or concealment, and then fell not only upon the garrison but on the monks, even massacring the priests who had been saying Mass for them. This noble abbey had for more than a thousand years an existence worthy of its origin. Mingling in the religious and warlike history of France, it was simultaneously or by turns occupied by knights and monks; the abode of faith and courage; an advanced sentinel in the direction of England, and thus affording protection against the foes of this world and of the next, defending alike with the cross and with the sword, and held in veneration by the whole of Christendom. During the ages of faith pilgrims came hither by thousands, from all lands, braving the danger of these treacherous sands, to invoke in this his sanctuary the prince and leader of the armies of heaven. The sacrilegious impiety of modern times could no more spare St. Michael’s Mount than so many other holy and beautiful relics of the past which it has seen fit to mutilate or destroy. The First Republic suppressed the monastery, drove out the monks, demolished a portion of their church, changed the name of Mont Saint-Michel to that of _le Mont Libre_, or the Free Mount, and turned it into a prison!—doubtless in order to prove the suitability of its new appellation. The first prisoners there were the priests of Brittany and Normandy. Prayer was thus at least not yet banished from its ancient abode. In 1811 Napoleon made of it a _Maison de Réclusion_, which, in 1818, became a _Maison de Détention_, and it was at the same time also a state prison. Rarely has any place seen more sad and strange vicissitudes. The chosen dwelling-place of those called to serve God in a religious life became the sink of every crime pursued and punished by society, and the population of Mount St. Michael was now recruited not from men who had received a holy vocation, but from courts of assize.
