The naval engagement of which Francesco Maria has given the preceding sketch was that of Lepanto or Curzolari, where Passeri states that he had with him a large body of his father's subjects, a fact which, although passed over in his own account of this his only military service, is confirmed by Armanni, who tells us that there were in the fleet above fifty from Gubbio alone, thirty of whom were officers, a circumstance on which the Prince was complimented by Don John. It is unnecessary here to add to the Prince's details. The general result of the engagement was most conclusive: the enemy's loss has been calculated at thirty thousand killed, ten thousand wounded, and fifteen thousand Christian slaves rescued from bondage, besides the destruction or capture of six hundred sail, and a vast booty. The Christian fleet consisted of above two hundred war-galleys, besides many other vessels of various sorts. "On bringing his wife from Ferrara to Pesaro [in January, 1572], they were magnificently received, and passed a gay carnival. In Lent he repaired to Rome, after visiting the holy house of Loreto, and was there entertained by his uncles, the Cardinals of Urbino and Farnese. Pius V. insisted upon very graciously admitting him to an audience, notwithstanding an illness of which he soon died....[81] Francesco Maria was also distinguished by his successor, Gregory XIII., but, on suddenly being recalled by his father, he at once, though reluctantly, obeyed. Soon afterwards, he was attacked by a severe illness, which lasted for three months, aggravated by a false rumour of another naval engagement."
