A week ago I communicated to M. de Pomponne that I was to have a conference the next day with the Duke of Mantua. We met, as had been concerted, at midnight, in a small open place, which is at an equal distance from his house and mine. I was an entire hour with him, and not only did I tell him all that your Majesty had desired me to apprize him of, and which he had already learned from the Count Matthioli, but besides, I re-assured him, as much as I was able, upon the subject of the constant, and indeed well-grounded, alarms he is in with regard to the Spaniards. I did not explain myself to him with regard to the present your Majesty intends making to him in money, as soon as the treaty shall be concluded; but contented myself with promising that he should have reason to be content with it. He appeared to be much satisfied with our conversation; and, on my side, I have no less reason to be so; since he has confirmed to me all that the Count Matthioli told me from him. I have given so exact an account of these things to your Majesty in the letters I have had the honour to write to yourself and to M. de Pomponne, that it is useless for me to enlarge more upon this subject. When we were upon the point of separating, the Duke of Mantua represented to me the risk he is in of being overwhelmed by the Spaniards, whose bad intentions he cannot doubt of, after their late earnest persuasions to him, to admit the Germans into Casale, to withdraw his garrison from Guastalla, and to declare himself openly and without delay in their favour. He added, that I must be aware, that under the resolution he had taken of serving your Majesty, both with his person and his territories, he would do nothing prejudicial to your interests; but that, if the Spaniards did not give him more money than what they were accustomed to furnish him with, for the support of the garrison of Casale, as they had declared to him was their intention, he should not be able to support the expense of it himself, or to preserve that fortress; that the danger was so pressing, that no time was to be lost in placing him in a state of safety, and that affairs went on so slowly by means of despatches, that he found himself obliged to send the Count Matthioli to your Majesty, to expose to you the state to which he finds himself reduced, and to implore you to deliver him from it as quickly as may be possible.
