The partizans of John Visconti insinuated to the Genoese that they had no other remedy than to place themselves under the protection of the Prince of Milan.

Petrarch was not ignorant of the Visconti's views; and it has been, therefore, suspected that he kept back his exhortatory epistle from his apprehension, that if he had despatched it, John Visconti would have made it the last epistle of his life.

The morning after writing it, he found that Genoa had signed a treaty of almost abject submission; after which his exhortation would have been only an insult to the vanquished.
The Genoese were not long in deliberating on the measures which they were to take.

In a few days their deputies arrived at Milan, imploring the aid and protection of John Visconti, as well as offering him the republic of Genoa and all that belonged to it.

After some conferences, the articles of the treaty were signed; and the Lord of Milan accepted with pleasure the possession that was offered to him.
Petrarch, as a counsellor of Milan, attended these conferences, and condoled with the deputies from Genoa; though we cannot suppose that he approved, in his heart, of the desperate submission of the Genoese in thus throwing themselves into the arms of the tyrant of Italy, who had been so long anxious either to invade them in open quarrel, or to enter their States upon a more amicable pretext.
