Though Frontenac was not the author of this severe measure, duty required him to enforce it. Perrot was a friend and defender of the coureurs de bois, whom he used as employees in the collection of peltries. Under his regime Montreal formed their headquarters. The edict gave them no concern, since they knew that between them and trouble stood their patron and confederate. Thus Frontenac found an excellent occasion to put Perrot in the wrong and to hit him through his henchmen. The only difficulty was that Frontenac did not possess adequate means to enforce the law. Obviously it was undesirable that he should invade Perrot's bailiwick in person. He therefore instructed the judge at Montreal to arrest all the coureurs de bois who were there. A loyal attempt was made to execute this command, with the result that Perrot at once intervened and threatened to imprison the judge if he repeated his effort. Frontenac's counterblast was the dispatch of a lieutenant and three soldiers to arrest a retainer of Perrot named Carion, who had shown contempt of court by assisting the accused woodsmen to escape. Perrot then proclaimed that this constituted an unlawful attack on his rights as governor of Montreal, to defend which he promptly imprisoned Bizard, the lieutenant sent by Frontenac, together with Jacques Le Ber, the leading merchant of the settlement. Though Perrot released them shortly afterwards, his tone toward Frontenac remained impudent and the issue was squarely joined. But a hundred and eighty miles of wilderness separated the governor of Canada from the governor of Montreal. In short, before Perrot could be disciplined he must be seized, and this was a task which if attempted by frontal attack might provoke bloodshed in the colony, with heavy censure from the king. Frontenac therefore entered upon a correspondence, not only with Perrot, but with one of the leading Sulpicians in Montreal, the Abbe Fenelon. This procedure yielded quicker results than could have been expected. Frontenac's letter which summoned Perrot to Quebec for an explanation was free from threats and moderate in tone. It found Perrot somewhat alarmed at what he had done and ready to settle the matter without further trouble. At the same time Fenelon, acting on Frontenac's suggestion, urged Perrot to make peace. The consequence was that in January 1674 Perrot acceded and set out for Quebec with Fenelon as his companion. Whatever Perrot's hopes or expectations of leniency, they were quickly dispelled. The very first conference between him and Frontenac became a violent altercation (January 29, 1674). Perrot was forthwith committed to prison, where he remained ten months. Not content with this success, Frontenac proceeded vigorously against the coureurs de bois, one of whom as an example was hanged in front of Perrot's prison.
