The Romans, in order to avoid the war, drove Pope Eugenius from their
city: and he, having with difficulty escaped, came to Florence, where
seeing the imminent danger of his situation, being abandoned by the
princes (for they were unwilling again to take up arms in his cause,
after having been so anxious to lay them aside), he came to terms with
the count, and ceded to him the sovereignty of La Marca, although, to
the injury of having occupied it, he had added insult; for in signing
the place, from which he addressed letters to his agents, he said in
Latin, according to the Latin custom, _Ex Girfalco nostro Firmiano,
invito Petro et Paulo_. Neither was he satisfied with this concession,
but insisted upon being appointed Gonfalonier of the church, which was
also granted; so much more was Eugenius alarmed at the prospect of a
dangerous war than of an ignominious peace. The count, having been
thus been reconciled to the pontiff, attacked Niccolo Fortebraccio, and
during many months various encounters took place between them, from
all which greater injury resulted to the pope and his subjects, than to
either of the belligerents. At length, by the intervention of the duke
of Milan, an arrangement, by way of a truce, was made, by which both
became princes in the territories of the church.

The war thus extinguished at Rome was rekindled in Romagna by Batista
da Canneto, who at Bologna slew some of the family of the Grifoni, and
expelled from the city the governor who resided there for the pope,
along with others who were opposed to him. To enable himself to retain
the government, he applied for assistance to Filippo; and the pope,
to avenge himself for the injury, sought the aid of the Venetians and
Florentines. Both parties obtained assistance, so that very soon two
large armies were on foot in Romagna. Niccolo Piccinino commanded for
the duke, Gattamelata and Niccolo da Tolentino for the Venetians and
Florentines. They met near Imola, where a battle ensued, in which the
