Not less remarkable during the long reign of Solyman than his conquests by his army were the exploits of his navy. It achieved victory in many hard-fought battles with Spain and Venice. There was no great disparity in naval force between the Turks and the Spaniards, but when the fleets of Venice and the Pope were combined with those of Spain, there was great superiority on their part in the number and size of vessels. In spite of this, in the two great battles where this combination was against them, the Turks were victorious, and generally, throughout Solyman’s reign, his fleets maintained a supremacy in the Mediterranean. This enabled him to add to his Empire the provinces of Algiers, Oran, and Tripoli, and numerous islands in the Ægean Sea, taken from Venice.
The Mussulman States of North Africa, at the commencement of Solyman’s reign, were in the hands of degenerate and incompetent Mahommedan rulers, who exercised little control over the Arabs of the hinterland. The cities on the coast were the haunts of pirates, who sometimes sailed under the flags of these States, but more often under no flag but their own. They preyed on the commerce of the Mediterranean, bringing their prizes into their ports and selling the captives as slaves, with the result that in Tunis alone there were twenty thousand Christian captives. These corsairs formed squadrons of ten or twenty galleys, under the command of admirals, chosen from the most daring and adventurous of them. They were called corsairs, but, in fact, they were mere pirates, knowing no law but their own, and that founded on robbery and murder. The sea-dogs in command of these pirates gained great experience in handling their ships and squadrons. They ravaged the coasts of Spain, Italy, and France, and even occasionally of England and Ireland, devastating the cities and villages and carrying away booty and captives.
It has been shown that Selim paid great attention to his navy, and increased his ships in number and size. Solyman followed the same course. But his admirals and captains did not compare in skill and daring with those of the pirate squadrons. When Solyman became aware of this, he most astutely invited the ablest and most experienced of these pirates to take service under the Ottoman flag, and to bring with them their ships and men. He gave high appointments to them, raised them to the rank of admirals and commanders-in-chief of his navy, over the heads of the officers of his regular service.
The first and most distinguished of these corsairs to take naval service under Solyman was Kheireddin, better known in history as Barbarossa. He was one of four brothers, of Greek descent, born in Mytilene, three of whom in early life took to piracy as a profession, under the pretence of legitimate commerce at sea. Two of them eventually lost their lives in the venture, but the third survived, prospered, and made money. He collected a squadron under his command and became the terror of the whole Mediterranean, capturing merchant vessels and devastating the coasts in all directions. Gathering strength in number of ships and men, he made war on his own account. He attacked Algiers and made himself master of that city and its surrounding district. But finding himself unequal to the task of maintaining an independent rule there, he recognized the supremacy of the Sultan of Turkey. He carried on his ships seventy thousand fugitive Moors from Andalusia, in Spain, and settled them at Algiers. Later, he was employed by Solyman in an attack on Tunis, which was then under the rule of Muley-Hasan, the twenty-second representative of the dynasty of Boni Hafss—a degenerate reprobate, who had murdered all but one of his forty-four brothers on his accession to the throne, and who spent his energies in recruiting a harem of four hundred good-looking lads. On the pretext of putting an end to this infamy, Barbarossa attacked the city of Tunis, and had no difficulty in getting possession of it and expelling the contemptible Sultan. He did not, however, remain many months in possession of it. Muley-Hasan appealed to the Emperor Charles for aid.
The Emperor, in personal command of a fleet of five hundred vessels and an army of thirty thousand men, attacked and defeated Barbarossa in a battle before the walls of Tunis, captured his vessels lying there, and drove him into the interior of the country. Although he had come there at the invitation of the Sultan of Tunis, and the inhabitants of the city had given no assistance to Barbarossa in defending it against the Spanish attack, the Emperor allowed his soldiers to sack it after the capture. A scene of almost incredible cruelty and destruction took place. Thirty thousand of the innocent inhabitants were massacred, and ten thousand were sold into captivity. The mosques and all the principal buildings were burnt and destroyed. No worse deed was ever perpetrated by any victorious Moslem army in that age. It resulted that Tunis, for a time, was rescued from Barbarossa and from Ottoman rule. Muley-Hasan was reinstated there on terms of close dependence on Spain. It was not till 1574 that Tunis finally fell into the hands of the Turks.
Barbarossa had made a splendid defence of the city. His force was quite inadequate for the purpose. Solyman was at the time engaged in war with Persia and could not give adequate support. Shortly after this, when war broke out between the Ottomans and Spain, the Sultan invited Barbarossa to Constantinople, and made him Grand Admiral of the Turkish fleet. In this capacity he fought in 1538 a great naval battle off Prevesa against the combined fleets of Spain, Venice, and the Pope, under Admiral Andrea Doria, in which he achieved victory, in spite of great inferiority of numbers and size of vessels. He appears to have been the first to adopt the manœuvre of breaking the line of the enemy’s fleet, for which three centuries later Nelson was so famous. The Turkish fleet numbered a hundred and thirty vessels, and that of the combined Christian Powers a hundred and sixty-seven. Six of the latter were captured and destroyed. The main body of the combined fleet drew off, under cover of the night. Later, Barbarossa accompanied Solyman in the attack on Corfu, which was heroically defended by the Venetians. The Sultan was compelled to withdraw from the island.
This failure at Corfu, and that before Vienna, were the only reverses which Solyman personally encountered in his numerous campaigns. Barbarossa, however, in the course of the war with the Venetians, succeeded in capturing from them all the many islands which they possessed in the Ægean Sea, with the exception of Crete and the few fortified places they held in the Morea. These were his last exploits. He died at Constantinople in 1546.
Others, however, of the same brood of corsairs or pirates succeeded Barbarossa in the Turkish navy, and maintained its reputation for successful daring. The most distinguished of them were Dragut (or Torghut) and Piale, both of them renegade subjects of Turkey who had taken to piracy as a profession. Dragut, a Croatian by birth, closely resembled Barbarossa in his career, in his prowess at sea, and in the terror which he created on the coasts of Italy and Spain. He had little respect for the allies of the Sultan, and captured their vessels as readily as those of his enemies. When called to account by the Porte for the destruction of some Venetian merchant ships, and summoned to Constantinople, he declined to go there, well knowing the fate in store for him. He betook himself, with his pirate squadron, to Morocco, which he made the base for piracy for some years. Later, Solyman, finding the need of such a daring spirit, invited him again to take service under the Ottoman flag, and promised to make him Governor of Tripoli, if he could capture it. Tripoli then belonged to the Knights of St. John at Malta. Dragut attacked and captured it, and annexed it to the Turkish Empire. Eventually Dragut was appointed Governor of Tripoli and, in this capacity, led a fleet in aid of the attack on Malta in 1565. He lost his life in an assault on the city.
Another such corsair was Piale, who, in his turn, after a long spell of piracy, was taken into the Ottoman naval service by Solyman, and rose to be commander-in-chief. He defeated the combined fleet of Spain, Venice, and the Pope, under command of Andrea Doria, sent to recapture Tripoli. He attacked and annexed for the Turks the province of Oran, on the African coast, westward of Algiers. He commanded the Turkish fleet in the attack on Malta in 1565, the last naval enterprise in Solyman’s reign.
