A History of Sea Power. Allan F. Westcott
Rome and taken the Pope captive. He then returned to Constantinople with 11,000 Christian captives.
Charles V was roused by this display of corsair power and barbarity to collect a force that should put an end to such raids. Barbarossa had recently added Tunis to his personal domains, and the great expedition of ships and soldiers which the emperor assembled was directed against that city. Despite the warning given by the King of France, Barbarossa was unable to oppose the Christian host with a force sufficiently strong to defend the city. The Christians captured it and the chieftain escaped only by a flight along the desert to the port of Bona where he had a few galleys in reserve. With these he made his way to Algiers before Andrea Doria could come up with him. The Christians celebrated the capture of Tunis by a massacre of some 30,000 inhabitants and returned home, thanking God that at last Barbarossa was done for. Indeed, with the loss of his fleet and his newly acquired province it seemed as if the great pirate was not likely to give much trouble, but the Christians had made the mistake of leaving the work only half done.
In 1537, two years after the fall of Tunis, the Sultan declared war on Venice. The Turkish fleet, although led by the Sultan Soliman himself, was defeated by the Venetians off Corfu. Doria, in the service of Charles V, caught and burned ten richly laden Turkish merchant ships and then defeated a Turkish squadron. The prestige of the Crescent on the sea was badly weakened by these events, but suddenly Barbarossa appeared and raided the islands of the Archipelago and the coasts of the Adriatic with a savagery and sweep unmatched by anything in his long career. He arrived in the Golden Horn laden with booty, and delivered to his master, the Sultan, 18,000 captives.
This exploit changed the complexion of affairs. During the winter of 1537–1538 the naval yards of Constantinople were busy with the preparations for a new fleet which should take the offensive against the Venetians and the Christians generally. In the spring Barbarossa got out into the Archipelago and, raiding at will, swept up another batch of prisoners to serve as galley slaves for the new ships. Meanwhile the Mediterranean states nerved themselves for a final effort. Venice contributed 81 galleys, the Pope sent 36, and Spain, 30. Later the Emperor sent 50 transports with 10,000 soldiers, and 49 galleys, together with a number of large sailing ships. Venice also added 14 sailing ships of war, or "nefs," and Doria 22; these formed a special squadron. The Venetian nefs were headed by Condalmiero in his flagship the Galleon of Venice, the most formidable warship in the Mediterranean, and the precursor of a revolution in naval architecture and naval tactics.

| 16TH CENTURY GALLEY |
Although the sailing ship was coming more and more into favor because of the discoveries across the Atlantic, the galley was the man of war of this period. The dromons of the Eastern empire, with their stout build and two banks of oars, had given way to a long, narrow vessel with a single bank of oars which had been developed by men who lived on the shores of the sheltered lagoons of the Adriatic. The prime characteristic of this type was its mobility. For the pirate whose business it was to lie in wait and dash out on a merchantman, this quality of mobility—independence of wind and speed of movement—was of chief importance. Similarly, in order to combat the pirate it was necessary to possess the same characteristic. Of course, as in all the days of rowed ships, this freedom of movement was limited by the physical exhaustion of the rowers. In the ships of Greek and Roman days these men had some protection from the weapons of the enemy and from the weather, but in the 16th century galley, whether Turkish or Christian, they were chained naked to their benches day and night, with practically nothing to shelter them from the weather or from the weapons of an enemy. So frightful were the hardships of the life that the rowers were almost always captives, or felons who worked out their sentences on the rowers' bench. An important difference between the galley of this period and the earlier types of rowed ship is the fact that in the galley there was but one row of oars on a side, but these oars were very long and manned by four or five men apiece.
A typical galley was about 180 feet over all with a beam of 19 feet and a depth of hold of about 7–½ feet. A single deck sloped from about the water line to a structure that ran fore and aft amidships, about six feet wide, which served as a gangway between forecastle and poop and gave access to the hold. The forecastle carried the main battery of guns, and was closed in below so as to provide quarters for the fighting men. The poop had a deck house and a smaller battery; this deck also was closed in, furnishing quarters for the officers. There were two or three masts, lateen rigged, adorned in peace or war with the greatest profusion of banners and streamers. Indeed huge sums of money were expended on the mere ornament of these war galleys, particularly in the elaborate carvings that adorned the stern and prow.
In the conflict of Christian and Moslem, when Constantinople was the capital of Christendom, Greek fire on two critical occasions routed the Saracens. This substance was never understood in western Europe, and for centuries the secret was carefully preserved in the eastern capital. In the thirteenth and fourteenth centuries, it was used by the Moslem against the Christian, but the discovery of gunpowder soon made the earlier substance obsolete. In the 16th century cannon had already reached considerable dimensions, but in a naval battle between galleys these weapons were not used after the first volley or so. The tactics were little different from those of the day of the trireme, consisting simply of ramming, and fighting at close quarters with arquebus, bows, pike, and sword.
Twenty feet from the bows of every galley projected her metal beak, and all her guns pointed forward; hence in the naval tactics of the period everything turned on a head-on attack. The battle line, therefore, was line abreast. For the same reasons a commander had to fear an attack on his flank, and he maneuvered usually to get at least one flank protected by the shore. The battle line in the days of the galley could be dressed as accurately as a file of soldiers, but the fighting was settled in a close mêlée in which all formation was lost from the moment of collision between the two fleets.
The Campaign of Prevesa
Such were the men of war and the tactics common to Christian and corsair during the 16th century. While the Christians were slowly collecting their armada, Barbarossa, with a force of 122 galleys, set out to catch his enemy in detail if he could. Pirate as he was, the old ruffian had a clear strategic grasp of what he might do with a force that was inferior to the fleet collecting against him. The Christians were to mobilize at Corfu. The Papal squadron had collected in the Gulf of Arta, and Barbarossa made for it. By sheer luck just before he arrived it had moved to the rendezvous. If he had followed it up immediately, he might have crushed both the Papal and Venetian contingents, because Doria and the Spanish fleet had not yet arrived; but apparently he felt uncertain as to just how far off these reënforcements were and therefore did not attempt the stroke. Instead, he took up a defensive position in the Gulf of Arta, exactly where Antony had collected his fleet before the battle of Actium.
In September (1538) the Christian fleet under Doria left Corfu and crossed to the Gulf. Barbarossa had drawn up his force in battle array inside the entrance, under the guns of the Turkish fortress at Prevesa. Since this entrance is obstructed by a bar with too little water for Doria's heavier ships, he lay outside. Thus the two fleets faced each other, each waiting for the other to make the next move. For the first time in their careers the greatest admiral on the Christian side was face to face with the greatest on the Moslem side. Both were old men, Doria over seventy and Barbarossa eighty-two. The stage was set for another decisive battle on the scene of Actium. The town of Prevesa stood on the site of Octavius's camp, and again East and West faced each other for the mastery of the sea. With the vastly greater strength of the Christian fleet, and the known skill of its leader, everything pointed to an overwhelming victory for the Cross. What followed is one of the most amazing stories in history.
Having the interior lines and the smooth anchorage, Barbarossa had only to watch his enemy go to pieces in the open roadstead in trying to maintain a blockade. His officers, however, scorned such a policy, and, being appointees of the Sultan and far from subordinate in spirit to their chief, they were finally able to force his hand and compel him to offer battle to the Christians by leaving the security of the gulf and the fortress and going out into the open,
