And so it was.

San Severino and his brothers took their place in the ranks of the infantry, and Sforza took his among the baggage, clad in a monk's frock, with the hood pulled over his eyes.
The army marched off; but the Swiss, who had first trafficked in their blood, now trafficked in their honour.

The French were warned of the disguise of Sforza and his generals, and thus they were all four recognised, and Sforza was arrested by Trimouille himself.

It is said that the price paid for this treason was the town of Bellinzona; far it then belonged to the French, and when the Swiss returned to their mountains and took possession of it, Louis XII took no steps to get it back again.
When Ascanio Sforza, who, as we know, had stayed at Milan, learned the news of this cowardly desertion, he supposed that his cause was lost and that it would be the best plan for him to fly, before he found himself a prisoner in the hand's of his brother's old subjects: such a change of face on the people's part would be very natural, and they might propose perhaps to purchase their own pardon at the price of his liberty; so he fled by night with the chief nobles of the Ghibelline party, taking the road to Piacenza, an his way to the kingdom of Naples.

But when he arrived at Rivolta, he remembered that there was living in that town an old friend of his childhood, by name Conrad Lando, whom he had helped to much wealth in his days of power; and as Ascanio and his companions were extremely; tired, he resolved to beg his hospitality for a single night.
Conrad received them with every sign of joy, putting all his house and servants at their disposal.
