The Duke of Calabria confined within limits 18 knights and citizens of Siena. He also kept his soldiers in the city, so that he was master of the situation. And the Sienese did not consider it at all just that he should act in this way, but he chose to do so. He had the idea of acting in the same way with regard to us; but please God, by a great miracle, it happened that on the 6th August the Turkish army came to Otranto and began to besiege it; so it was necessary to leave our neighbourhood, at the king's command, and return to defend the kingdom. The Turks were encamped in three places, being at Rodi (Rhodes), and with the Hungarians, besides at Otranto.
A number of soldiers and militia were sent from here to Piancaldoli, men of the Romagnuoli and of the Mugello; so that by the 29th we took it. The commandant of the fortress, who was from Imola, capitulated; and he was given 4 thousand florins and a house, and the right of bearing arms for life, here in Florence, where he remained.
12th January (Monday). Soldiers were mustered for Pisa and sent there, and we hoped to win it back shortly.
