The result of this trifling pique between the two governments was great hindrance to commerce, but very often that which bears only upon the private interest of the people is lightly treated by the rulers.
I did not wish to be quarantined, and determined on evading it.

It was rather a delicate undertaking, for in Venice the sanitary laws are very strict, but in those days I delighted in doing, if not everything that was forbidden, at least everything which offered real difficulties.
I knew that between the state of Mantua and that of Venice the passage was free, and I knew likewise that there was no restriction in the communication between Mantua and Modena; if I could therefore penetrate into the state of Mantua by stating that I was coming from Modena, my success would be certain, because I could then cross the Po and go straight to Venice.

I got a carrier to drive me to Revero, a city situated on the river Po, and belonging to the state of Mantua.
The driver told me that, if he took the crossroads, he could go to Revero, and say that we came from Mantua, and that the only difficulty would be in the absence of the sanitary certificate which is delivered in Mantua, and which was certain to be asked for in Revero.

I suggested that the best way to manage would be for him to say that he had lost it, and a little money removed every objection on his part.
When we reached the gates of Revero, I represented myself as a Spanish officer going to Venice to meet the Duke of Modena (whom I knew to be there) on business of the greatest importance.

The sanitary certificate was not even demanded, military honours were duly paid to me, and I was most civilly treated.
