On this occasion the Greeks had a good cause, and were fighting to save their country and its liberties. Undaunted by the numbers of the opposing fleet, they bent to their long oars and came down in fine style. The Athenians became engaged first, then the Æginetans, and then the battle became general. The Greeks had the advantage of being in rapid motion when they struck the Persian fleet, most of which had not, at that critical moment, gathered way. The great effect of a mass in motion is exemplified in the act of a river steamboat running at speed into a wharf; the sharp, frail vessel is seldom much damaged, while cutting deep into a mass of timber, iron and stone. Many of the Persian vessels were sunk at once, and a great gap thereby made in their line. This was filled from their immense reserve, but not until after great panic and confusion, which contributed to the success of the Greeks. The Persian Admiral commanding the left wing, seeing that it was necessary to act promptly in order to effectually succor his people, bore down at full speed upon the flagship of Themistocles, intending to board her. A desperate hand-to-hand struggle ensued, and the vessel of Themistocles was soon in a terrible strait; but many Athenian galleys hastened to his rescue, and the large and magnificent Persian galley was sunk by repeated blows from the sharp beaks of the Greeks, while Ariamenes, the Admiral, was previously slain and thrown overboard. At this same moment the son of the great Darius, revered by all the Asiatics, fell, pierced by a javelin, at which sight the Persians set up a melancholy wailing cry, which the Greeks responded to with shouts of triumph and derision. Still, the Persians, strong in numbers, renewed and maintained the battle with great fury; but the Athenian fleet cut through the Phenician line, and then, pulling strong with starboard and backing port oars, turned short round and fell upon the Persian left flank and rear. A universal panic now seized the Asiatics; and in spite of numbers, they broke and fled in disorder--all, that is, except the Dorians, who, led by their brave queen in person, fought for their new ally with desperate valor, in the vain hope of restoring order where all order was lost. The Dorian queen, Artemisia, at last forced to the conviction that the fugitives were not to be rallied, and seeing the waters covered with wreck, and strewn with the floating corpses of her friends and allies, reluctantly gave the signal for retreat.
