A History of Sea Power

by William Oliver Stevens; Allan F. Westcott

The winning stroke in this campaign was the tremendous naval victory at the mouth of the Bosphorus, and this, even more emphatically than Constantine's victory in 677, deserves to be called another Salamis. Not only did it save the Christian empire but it checked the Caliphate at the summit of its power and started it on its decline. Not for thirty years afterwards was the Saracen able to put any considerable fleet upon the sea.

It was ten years after the Arab defeat at Constantinople that the armies of the west began the other part of Muza's project—the conquest of the Franks. By this time the Frankish power was united and able to present a powerful defense. In six bitterly contested battles between Tours and Poitiers in 732 Charles Martel defeated the Arabs in a campaign that may well be called the Marathon, or better, the Platæa, of the Middle Ages, for it completed the work done by the imperial navy at Constantinople. From this time forward the power of the Saracen began to ebb by land and sea.

As it ebbed, the new cities of Genoa, Pisa, and Venice began to capture the trade and hold the control of the sea that once had been Saracen, until the Christian control was so well established as to make possible the Crusades. Later, as we shall see, a second invasion of Mohammedans, the Turks, ably assisted by the descendants of the Arabs who conquered Spain, once more threatened to control the Mediterranean for the cause of Islam. But the Persian Gulf and the Indian Ocean, which fell into the hands of the Arabs as soon as they took to the water, remained in Arab hands down to the times of the Portuguese. In those waters, because they were cut off from the Mediterranean, the Saracen had no competitor. As early as the eighth century Ceylon was an Arab trading base, and when the Portuguese explorers arrived at the end of the 15th century they found the Arabs still dominating the water routes of India and Asia, holding as they had held for seven centuries a monopoly of the commerce of the east.

Of the Mediterranean during the struggle between Christian and Saracen a recent English writer makes the following suggestive comment:

"The function of the Mediterranean has thus undergone a change. In early times it had been a barrier; later, under the Phœnicians, it became a highway, and to the Greeks a defense. We find that the Romans made it a basis for sea power and subdued all the lands on its margin. With the weakening of Rome came a weakening of sea power. The Barbary states and Spain became Saracen only because the naval power of the eastern empire was not strong enough to hold the whole sea, but neither was the Saracen able to gain supreme control. Thus the conditions were the same as in the earlier days of the conflict between Rome and Carthage: the Mediterranean became a moat separating the rivals, though first one and then the other had somewhat more control. The islands became alternately Saracen and Christian. Crete and Sicily were held for centuries before they were regained by a Christian power."[1]

The victory of 718 saved Constantinople from any further peril from the Arabs, but it was again in grave peril, two centuries later, when a sudden invasion of Russians in great force threatened to accomplish at a stroke what the Saracens had failed to do in three great expeditions. The King of Kiev, one of the race of Vikings that had fought their way into southern Russia, collected a huge number of ships, variously estimated from one to ten thousand, and suddenly appeared in the Bosphorus. Probably there were not more than 1500 of these vessels all told and they must have been small compared with the Christian dromons; nevertheless they presented an appalling danger at that moment. The Christian fleet was watching Crete, the army was in the east winning back territory from the Arabs, and Constantinople lay almost defenseless. The great walls could be depended an to hold off a barbarian army, but a fleet was needed to hold the waterways; otherwise the city was doomed.

In the Horn lay a few antiquated dromons and a few others still on the stocks. To Theophanes the Patrician was given this nucleus of a squadron with which to beat back the Russians. Desperate and even hopeless as the situation appeared, he went to work with the greatest energy, patching up the old ships, and hurrying the completion of the new. Meanwhile the invaders sent raiding parties ashore that harried the unprotected country districts with every refinement of cruelty. In order to make each ship count as much as possible as an offensive unit, Theaphanes made an innovation by fitting out Greek fire tubes on the broadsides as well as in the bows. This may be noted as the first appearance of the broadside armament idea, which had to wait six hundred years more before it became finally established.

When the new ships had been completed and the old ones made serviceable, Theophanes had exactly fifteen men of war. With this handful of vessels, some hardly fit to take the sea, he set out from the Horn and boldly attacked the Russian fleet that blocked the entrance to the strait. Never was there a more forlorn hope. Certainly neither the citizens on the walls nor the men on the ships had any expectation of a return.

What followed would be incredible were it not a matter of history. These fifteen ships were immediately swallowed up by the huge fleet of the enemy, but under the superb leadership of Theophanes each one fought with the fury of desperation. They had one hope, the weapon that had twice before saved the city, Greek fire. The Russians swarmed alongside only to find their ships taking fire with a flame that water would not quench. Contempt of their feeble enemy changed soon to a wild terror. There was but one impulse, to get out of reach of the Christians, and the ships struggled to escape. Soon the whole Russian fleet was in wild flight with the gallant fifteen in hot pursuit. Some of these could make but slow headway because of their unseaworthiness, but when all was over the Russians are said to have lost two-thirds of their entire force. The invaders who had been left on shore were then swept into the sea by reënforcements that had arrived at Constantinople, and not a vestige was left of the Russian invasion. Once more Greek fire and the Christian navy had saved the empire; and for sheer audacity, crowned with a victory of such magnitude, the feat of Theophanes stands unrivaled in history.
