Six ambassadors left Florence to visit the said Pope; namely: Lorenzo de' Medici, Messer Domenico Martegli, Messer Agnolo della Stuffa, Messer Bongianni Gianfigliazzi, Piero Minerbetti and Donato Acciaiuolo; and the said Pope made Piero Miberbetti a knight and he returned to Florence with this title.
We captured Pietrasanta, which capitulated to Lorenzo de' Medici, and on the 11th we took the fortress. Piero, son of Filippo Tornabuoni, was made warden, and Jacopo Acciauoli commissary; Jacopo Acciauoli being put in command of the walls. The news reached here at 14 at night (10 p.m.), and the next day the shops remained closed, and there were great rejoicings and bonfires. And the same day Messer Bongianni Gianfigliazzi, another commissary there, was brought back to Florence dead.
