Six years had passed since his release from prison, when, in the March of 1430, there was plotted by the Carmelites of Melun and certain burgesses of Paris that conspiracy which we mentioned on the occasion of Jeanne's departure for l'Île de France. It was not the first plot into which the Carmelites had entered; they had plotted that rising which had been on the point of breaking out on the Day of the Nativity, when the Maid was leading the attack near La Porte Saint-Honoré; but never before had so many burgesses and so many notables entered into a conspiracy. A clerk of the Treasury, Maître Jean de la Chapelle, two magistrates of the Châtelet, Maître Renaud Savin and Maître Pierre Morant, a very wealthy man, named Jean de Calais, burgesses, merchants, artisans, more than one hundred and fifty persons, held the threads of this vast web, and among them, Jaquet Guillaume, Seigneur de l'Ours.
The Carmelites of Melun directed the whole. Clad as artisans, they went from King to burgesses, from burgesses to King; they kept up the communications between those within and those without, and regulated all the details of the enterprise. One of them asked the conspirators for a written undertaking to bring the King's men into the city. Such a demand looks as if the majority of the conspirators were in the pay of the Royal Council.
In exchange for this undertaking these monks brought acts of oblivion signed by the King. For the people of Paris to be induced to receive the Prince, whom they still called Dauphin, they must needs be assured of a full and complete amnesty. For more than ten years, while the English and Burgundians had been holding the town, no one had felt altogether free from the reproach of their lawful sovereign and the men of his party. And all the more desirous were they for Charles of Valois to forget the past when they recalled the cruel vengeance taken by the Armagnacs after the suppression of the Butchers.
One of the conspirators, Jaquet Perdriel, advocated the sounding of a trumpet and the reading of the acts of oblivion on Sunday at the Porte Baudet.
"I have no doubt," he said, "but that we shall be joined by the craftsmen, who, in great numbers will flock to hear the reading."
He intended leading them to the Saint Antoine Gate and opening it to the King's men who were lying in ambush close by.
Some eighty or a hundred Scotchmen, dressed as Englishmen, wearing the Saint Andrew's cross, were then to enter the town, bringing in fish and cattle.
"They will enter boldly by the Saint-Denys Gate," said Perdriel, "and take possession of it. Whereupon the King's men will enter in force by the Porte Saint Antoine."
The plan was deemed good, except that it was considered better for the King's men to come in by the Saint-Denys Gate.
On Sunday, the 12th of March, the second Sunday in Lent, Maître Jean de la Chapelle invited the magistrate Renaud Savin to come to the tavern of La Pomme de Pin and meet divers other conspirators in order to arrive at an understanding touching what was best to be done. They decided that on a certain day, under pretext of going to see his vines at Chapelle-Saint-Denys, Jean de Calais should join the King's men outside the walls, make himself known to them by unfurling a white standard and bring them into the town. It was further determined that Maître Morant and a goodly company of citizens with him, should hold themselves in readiness in the taverns of the Rue Saint-Denys to support the French when they came in. In one of the taverns of this street must have been the Seigneur de l'Ours, who, dwelling near by, had undertaken to bring together divers folk of the neighbourhood.
