On May 14, 1659, the king, repenting of his letter to Mgr. de Harlay, sent two _lettres de cachet_, one to Laval and the other to Governor d'Argenson, derogating the appointment of May 11th.
The king's letter to d'Argenson contained this: "The letter that I have accorded to the archbishop of Rouen, it is my intention that neither he nor the grands vicaires shall avail themselves of, until by the authority of the church it has been declared if this archbishop is in the right in his pretension that new France is in his diocese."
All these letters arrived by the St. André on September 8th, with the reinforcement brought back by Marguerite Bourgeoys and Jeanne Mance.
After the conflicting nature of their contents were mastered the position of de Queylus remained as after his submission.
Queylus returned to Montreal and later came back to Quebec, from which he departed on October 2d on the St. André on its return voyage.
The causes of his departure are shrouded in silence, and in guarded words d'Argenson writes: "I do not send you the reasons in writing for fear lest the letter shall fall into other hands."
Dollier de Casson says: "After the arrival of the reinforcement and of the Hospitalières at Ville Marie we witnessed the return of M. de Queylus to France, which afflicted this place very much," adding as a commentary: "Thus in this life are its sweets mixed with bitterness." Laval in his letter to the Propaganda laconically says: "In Galliam ipse transfretavit" (he sailed over to France).
This would look as if the voyage was of a voluntary nature. It was otherwise. Laval feared the opposition of de Queylus; he looked upon him as a rival, a disturber of the peace by his continued presence in the country, and had written to France shortly after his arrival, asking a _lettre de cachet_ for his removal. M. de Queylus was a powerful personality and had the support of an active minority. Already on his return to Montreal in the previous year the two other secular priests, chaplains of the convent, at Quebec, had left Canada on this account, and sixty persons had accompanied him on his journey back to Montreal on that occasion.
After his recent visit to Laval and while he was welcoming new recruits at Montreal, the _lettre de cachet_ arrived for his departure.
