The roads being good, and the days as long as they are at present, a body of cavalry can go in less than thirty hours from Pignerol to Casale. There is no fortified place through which we should be obliged to pass, and I am not aware of any difficulty that we could find on the passage, provided we took the country by surprise in our march. I have thought it right to state this to you, Sir, because the possibility of using this degree of diligence may materially assist the measures you may wish to take. The Duke of Mantua has never been at Casale, which seems to me an obstacle to the finding good excuses for his going there, at a time when his conduct is so much watched and suspected. But we could do very well without him, if he is always well-intentioned, and if he is the master of a good part of his garrison. The Governor is of Mantua, and therefore his actual subject; which is perhaps a favourable circumstance. I am, &c. CATINAT.[268] [268] From the work of M. Roux (Fazillac). No. 78. CATINAT TO LOUVOIS. Rumours of Catinat’s being at Pignerol.--Civilities of Saint-Mars to him. April 15th, 1679. SIR, M. d’Herleville must have received some letters from Paris by the last post, which have given him the suspicion that I might be here; at least, he has put some leading questions on the subject to M. de Chanois: he is not a man without curiosity, and he thought by these means to gain certain intelligence. As I have been now a long while absent, and there has been no doubt at Paris of some design in agitation in these parts, on account of the troops which have been sent here, it is probable that some reasoner of the regiment of Guards, or some other person, may have given him this idea.
