And now yet another invitation came to Kheyr-ed-din. Andrea Doria had defeated the Turks at Patras and in the Dardanelles. Like the policy of the corsairs, after each victory the Christian admiral employed the infidel captives to work at the oars of his galleys. Thus it was that the Sultan of Turkey—Solyman the Magnificent—realising that the Christian admiral was draining the best Turkish seafaring men, determined to invite Kheyr-ed-din to help him against Andrea Doria.
