[31] On Charles's expedition to Tunis, consult Marmol, Hājji Khalīfa, Robertson, Morgan, Von Hammer, and Broadley. In the last will be found some interesting photographs of Jan Cornelis Vermeyen's pictures, painted on the spot during the progress of the siege, by command of the Emperor, and now preserved at Windsor. All the accounts of the siege and capture show discrepancies which it seems hopeless to reconcile. [32] _Hist. of Algiers_, 286. IX. THE SEA-FIGHT OFF PREVESA. 1537. When Barbarossa returned to Constantinople Tunis was forgotten and Minorca alone called to mind: instead of the title of Beglerbeg of Algiers, the Sultan saluted him as Capudan Pasha or High Admiral of the Ottoman fleets. There was work to be done in the Adriatic, and none was fitter to do it than the great Corsair. Kheyr-ed-dīn had acquired an added influence at Stambol since the execution of the Grand Vezīr Ibrahīm,[33] and he used it in exactly the opposite direction. Ibrahīm, a Dalmatian by birth, had always striven to maintain friendly relations with Venice, his native state, and for more than thirty years there had been peace between the Republic and the Porte. Barbarossa, on the contrary, longed to pit his galleys against the most famous of the maritime nations of the Middle Ages, and to make the Crescent as supreme in the waters of the Adriatic as it was in the Aegean. Francis I. was careful to support this policy out of his jealousy of the Empire. The Venetians, anxious to keep on good terms with the Sultan, and to hold a neutral position between Francis and Charles V., found themselves gradually committed to a war, and by their own fault. Their commanders in the Adriatic and at Candia were unable to resist the temptation of chasing Ottoman merchantmen. Canale, the Proveditore of Candia, caught a noted Corsair, the "Young Moor of Alexander," as his victims called him, sunk or captured his galleys, killed his Janissaries, and severely wounded the young Moor himself;--and all this in Turkish waters, on Turkish subjects, and in time of peace. Of course when the too gallant Proveditore came to his senses and perceived his folly, he patched the young Moor's wounds and sent him tenderly back to Algiers: but the Sultan's ire was already roused, and when Venetian galleys actually gave chase to a ship that carried a Turkish ambassador, no apologies that the Signoria offered could wipe out the affront. War was inevitable, and Venice hastily made common cause with the Pope and the Emperor against the formidable host which now advanced upon the Adriatic.
