But his greatest glory was acquired in naval war. His battles with the Moors and Turks gave him fame and wealth, and after the battle of Pianosa (1519), in which, with six vessels, he conquered thirteen of the enemy’s; capturing several with the famous corsair Gad Ali’ he became the terror of Saracen ships. When the Fregosi were driven from power and their places taken by the Adorni, Doria, disdaining to serve under this family, sold his services to France, and took with him six galleys belonging to the Republic, which he never restored. The motive of this appropriation of public property was his bitter animosity to Spain, whose party the Adorni and the Republic had embraced. This animosity was rendered more violent by the sack of Genoa in 1522 by the Spanish army, a pillage so horrible that when the authors of it, Pescara, Colonna and Sforza, presented themselves to Pope Hadrian humbly asking pardon, the pontiff indignantly repulsed them, crying,--“I cannot, I ought not, I will not forgive you.” Doria was so incensed that he condemned to chains and the galleys, without hope of redemption, all Spaniards who fell into his hands. In the year 1527, Pope Clement VIII. was allied with his most Christian Majesty, with the Venitians the Florentines and other governments against the power of Charles. To further the objects of the alliance Francis sent Lautrec into Italy at the head of forty thousand men, and Andrea Doria besieged Genoa with a large force. It is not within our scope to describe how the Republic, through the influence of Cæsar Fregosi and Doria, went over to the party of France. Francis, to gratify the wishes of Andrea, entrusted the government to Teodoro Trivulzio, Antoniotto Adorno, having gracefully retired from the office of Doge. Doria having been created admiral of France, with a salary of thirty-six thousand crowns, rose to great fame, on account of his victories and those of his lieutenants. Among these victories, that of Filippino Doria in the gulf of Salerno, deserves a brief mention, both because it was won by Italian arms, and because something should be added to the accounts given by other authors. Lautrec, while besieging Naples, desired to blockade the port, so as to prevent the supply of provisions to its defenders, and sent for the galleys of Doria, seven of which were then in Leghorn, under the command of Filippino Doria Count of Sassocorbario and Canosa and Andrea’s cousin.
