The revival period ended in the mid-16th century due to a series of military failures. The Imperial fleet was decisively defeated by the Ottomans at the Battle of Preveza in 1538, a Genoese fleet was damaged by a series of storms during the 1541 Algiers expedition, a Genoese-Spanish fleet was defeated at Ponza in 1552, and the navy failed to stop a French force from capturing Corsica in 1553. Genoa sent a contingent of her fleet to a Christian alliance that was defeated by the Ottomans at the Battle of Djerba in 1560. However, in 1571 the Genoese navy contributed 29 galleys (53 ships in total) to the Holy League fleet at the pivotal Battle of Lepanto, during which the Genoese admiral Giovanni Andrea Doria smashed the right flank of the Ottoman fleet. The decisive Christian victory ended Ottoman domination of the Mediterranean.
