important facts in ancient naval history. It is fair to say that storms did far more to destroy fleets and naval expeditions than battles during the entire age of the oar. The opposite extreme was reached in Nelson's day. His lumbering ships of the line made wretched speed and straggling formations, but they were able to weather a hurricane and to keep the sea for an indefinite length of time.

As a final word on the beginnings of navies, emphasis should be laid on the enormous importance of these early mariners, such as the Cretans and the Phœnicians, as builders of civilization. The venturesome explorer who brought his ship into some uncharted port not only opened up a new source of wealth but also established a reciprocal relation that quickened civilization at both ends of his route. The cargo ships that left the Nile delta distributed the arts of Egypt as well as its wheat, and the richest civilization of the ancient world, that of Greece, rose on foundation stones brought from Egypt, Assyria, and Phœnicia. It may be said of Phœnicia herself that she built-up her advanced culture on ideas borrowed almost wholly from her customers. But control of the seas for trade involved control of the seas for war, and behind the merchantman stood the trireme. It is significant and appropriate that a Phœnician coin that has come down to us bears the relief of a ship of war.

In contrast with these early sea explorers and sea fighters stand the peoples of China and India. Having reached a high state of culture at an early period, they nevertheless, sought no contact with the world outside and became stagnant for thousands of years. Indeed, among the Hindus the crossing of the sea was a crime to be expiated only by the most agonizing penance. Hence these peoples of Asia, the most numerous in the world, exercised no influence on the development of civilization compared with a mere handful of people in Crete or the island city of Tyre. And for the same reason China and India ceased to progress and became for centuries mere backwaters of history.

It is worth noting also that the Mediterranean, leading westwards from the early developed nations of Asia Minor and Egypt, opened a westward course to the advance of discovery and colonization, and this trend continued as the Pillars of Hercules led to the Atlantic and eventually to the new world. For every nation that bordered the Mediterranean illimitable highways opened out for expansion, provided it possessed the stamina and the skill to win them. And in those days they were practically the only highways. Frail as the early ships were and great as were the perils they had to face, communications by water were far centuries faster and safer than communications by land. Hence civilization followed the path of the sea. Even in these early beginnings it is easy to see that sea-borne commerce leads to the founding of colonies and the formation of an empire whose parts are linked together by trade routes, and finally, that the preservation of such an empire depends an the naval control of sea. This was as true of Crete and Phœnicia as it was later true of Venice, Holland, and England.

CHAPTER II

ATHENS AS A SEA POWER

1. THE PERSIAN WAR

In determining to crush the independence of the Greek cities of the west, Darius was influenced not only by the desire to destroy a dangerous rival on the sea and an obstacle to further advances by the Persian empire, but also to tighten his hold on the Greek colonies of Asia Minor. Helped by the Phœnician fleet and the treachery of the Lesbians and Samians, he had succeeded in putting down a formidable rebellion in 500 B.C. In this rebellion the Asiatic Greeks had received help from their Athenian brethren on the other side of the Ægean; indeed just so long as Greek independence flourished anywhere there would always be the threat of revolt in the Greek colonies of Persia. Darius perceived rightly that the prestige and the future power of his empire depended on his conquering Greece.

In 492 he dispatched Mardonius with an army of invasion to subdue Attica and Eretria, and at the same time sent forth a great fleet to conquer the independent island communities of the Ægean. Mardonius succeeded in overcoming the tribes of Thrace and Macedonia, but the fleet, after taking the island of Thasus, was struck by a storm that wrecked three hundred triremes with a loss of 20,000 lives. As the broken remnants of the fleet returned to Asia, leaving Mardonius with no sea communications, and harassed by increasing opposition, he was compelled to retreat also. In 490 Darius sent out another army under Mardonius, this time embarking it on a fleet of 600 triremes which succeeded in arriving safely at the coast of Attica in the bay of Marathon. While the army was disembarking it was attacked by Miltiades and utterly defeated. The second expedition, therefore, came to nothing. But Marathon can hardly be called a decisive battle because it merely postponed the invasion; it affected in no way the communications of the Persians and it did not weaken seriously their military resources.

The great savior of Greece at this crisis was the Athenian, Themistocles. He foresaw the renewed efforts of the Persian king to destroy Greece, and realized also that the most vital point in the coming conflict would be the control of the sea. Accordingly he urged upon the Athenians the necessity of building a powerful fleet. In this policy he was aided by one of those futile wars so characteristic of Greek history, a war between Athens and the island of Ægina. In order to overcome the Æginetans, who had a large fleet, the Athenians were compelled to build a larger one, and by the time this purpose was accomplished rumors came that the Persian king was getting ready another invasion of Greece.

Campaign of Salamis

The third attempt was undertaken ten years after the second, in the year 480, under Xerxes, the successor to Darius. This time the very immensity of the forces employed was to overcome all opposition and all misfortunes. An army, variously estimated at from one to five million men, crossed the Hellespont on a bridge of boats to invade the peninsula from the north, while a fleet of 1200 triremes was assembled to insure the command of the sea.

Against the unlimited resources of the Persian empire and the unity of plan represented by Xerxes and his generals, the Greeks had little to offer. They possessed the two advantages of the defensive, knowledge of the terrain and interior lines,[1] but their resources were small and their spirit divided.
