If you, Gentlemen, find any appearance of probability in my remark, and if you think it can interest the public, you are welcome to insert it in your Journal, &c.
The Baron de Heiss.
Formerly Captain of the Regiment of Alsace.
Phalsbourg,
June 28, 1770.
Letter on the subject of the Man in the Iron Mask, announced in the preceding one.
Gentlemen,
One of my friends tells me, that he has read in the “Histoire abrégée de l’Europe,” (Vol. ii. p. 33.), that it was said, that the Duke of Mantua had had the intention of selling his capital town; but that the author of this History did not believe it.
You are ill-informed; it is certain that this affair was negociated, and that it was much advanced towards a conclusion. The secretary of the Duke, who had much influence with his master, dissuaded him from this design; but the doing so cost him very dear, as you shall soon learn.
This faithful Minister made the Duke understand, that it was necessary for his interest and his honour to preserve his Duchy, and thus made him change his intention; he did still more, he obliged him to unite himself with the other Princes of Italy, in order to oppose the designs of France. It was he who negociated the interview of the different princes, which took place at Venice last winter, during the Carnival: this time was chosen in order the better to conceal the plans which were in agitation. You are without doubt aware, that it is not an extraordinary circumstance to see many princes and persons of condition at Venice during that period. This Secretary went afterwards to Rome, where he remained some time; he then visited almost all the Courts of Italy; he went to Venice and Genoa, and he succeeded every where so well, that he had almost entirely detached all those powers from the interests of France. Finally he went to Turin with the same intention. As he believed his negociations to be very secret he often visited the Marquis D’Arcy, the French Ambassador at the Court of Savoy; but what can escape the penetrating eyes of France? The minister of that crown had been informed of all the designs of the Secretary, before his arrival at Turin. He, however, paid him many civilities, asked him very often to dinner, and finally invited him to come and hunt with him, at some distance from Turin. The Secretary, who had no time to lose, and who thought the moment of the absence of the French ambassador very proper for his negociations, excused himself at first upon the plea of his having no horses; the Ambassador offered to lend them to him, and the Secretary dared no longer refuse, from fear lest some portion of the truth should be suspected. The day for the hunting being arrived, they set off together; but they were hardly at the distance of a league from the town, when the Secretary was surrounded by ten or twelve horsemen, who seized him, disguised him, masked him, and conducted him to Pignerol. Without doubt he was well aware who had played him this trick, but he had no means of resistance. At Pignerol he was thought to be too near Italy, and, though he was guarded very carefully, it was feared that the walls might tell tales; he was therefore removed from thence, and conducted to the Islands of Saint Margaret, where he at present is, under the care of M. de Saint-Mars, who is the Governor. This is a piece of news doubtless very surprising, but not on that account the less true.
I am, &c.
