Когда я стану царь, поставлю…

Строго говоря, первый случай скорее всего является вымыслом, а то и подлогом. По крайней мере этот случай рассматривается в книге Some Lies and Errors of History by the Rev. Reuben Parsons, D.D.
Если кратко, то Карл IX вообще не отдавал упомянутого приказа губернаторам,
Вот как раз фрагмент посвященный виконту Д’Орт ( Viscount d’Orthez):

It was not intended that the massacre should extend beyond Paris. We learn from Tavannes that the popular fury rendered the massacre general, “to the great regret of its advisers, they having resolved on the death of only the leaders and the factious.” They who held that the orders to slaughter the Huguenots had been sent into the provinces, adduce in proof only two letters: one from the Viscount d’Orthez, governor of Bayonne, to Charles IX.; and one from Catherine to Strozzi, who was 272 watching for an opportunity to surprise La Rochelle, one of the four cities
accorded to the Calvinists. Now, there is very good reason for regarding both these letters as unauthentic, and no argument can be urged in their favor. The first letter, whatever some authors may say, is not found in De Thou, not even in the Geneva edition of 1620; and this writer’s Huguenot proclivities and his aversion to Charles IX. would not have allowed him to overlook it, had he deemed it authentic. It is given only by the malevolent D’Aubigné in these words: “I commence with Bayonne, where a courier arrived with orders to cut in pieces the men, women, and children of Dax who had sought refuge in the prison. The Viscount d’Orthez, governor of the frontier, thus replied to the king; “Sire, I have communicated the order of your Majesty to the inhabitants and soldiers of the garrison; and have found them to be good citizens and brave warriors, but not executioners. Therefore they and I supplicate your Majesty to employ them in any possible, even though hazardous, matters,’ ” etc. But the Calvinist martyrologist furnishes us with reasons for supposing that no such orders as the above were expedited, either to d’Orthez or to any other governors in the provinces. This author, whose work is 273 a veritable “Lives of the Saints” for the French Protestants, says nothing, save in one case,
of such instructions; and certainly he was interested in chronicling them, had he known of them. But, on the contrary, he tells us that the murderers “at Orleans resolved to put their hands to the work without any orders from the governor, D’Entragues;” that those of Bourges “sent Marueil in haste to the court, but he returned bearing no commands;” that Charles IX. wrote many letters to Bordeaux to the effect that he “had not intended that execution to extend beyond Paris.” The exception to which we have alluded is that of Rouen, the Governor of which city, says the martyrologist, received orders “to exterminate those of the religion;” but this assertion is contradicted, observes Barthélemy,8 by the inactivity of the governor, and by the date of the Rouen murders, which occurred nearly a month after those of Paris.
