It was well understood, therefore, that the assembling of the fleet, and giving battle to the Persians where they now were, was a plan adopted mainly for the defense and benefit of the Athenians. The Athenians, accordingly, waived their claim to command, secretly resolving that, when the war was over, they would have their revenge for the insult and injury. A Spartan was accordingly appointed commander of the fleet. His name was Eurybiades. Things were in this state when the two fleets came in sight of each other in the strait between the northern end of Euboea and the main land. Fifteen of the Persian galleys, advancing incautiously some miles in front of the rest, came suddenly upon the Greek fleet, and were all captured. The crews were made prisoners and sent into Greece. The remainder of the fleet entered the strait, and anchored at the eastern extremity of it, sheltered by the promontory of Magnesia, which now lay to the north of them. The Greeks were amazed at the immense magnitude of the Persian fleet, and the first opinion of the commanders was, that it was wholly useless for them to attempt to engage them. A council was convened, and, after a long and anxious debate, they decided that it was best to retire to the southward. The inhabitants of Euboea, who had been already in a state of great excitement and terror at the near approach of so formidable an enemy, were thrown, by this decision of the allies, into a state of absolute dismay. It was abandoning them to irremediable and hopeless destruction. The government of the island immediately raised a very large sum of money, and went with it to Themistocles, one of the most influential of the Athenian leaders, and offered it to him if he would contrive any way to persuade the commanders of the fleet to remain and give the Persians battle where they were. Themistocles took the money, and agreed to the condition. He went with a small part of it--though this part was a very considerable sum--to Eurybiades, the commander-in-chief, and offered it to him if he would retain the fleet in its present position. There were some other similar offerings made to other influential men, judiciously selected. All this was done in a very private manner, and, of course, Themistocles took care to reserve to himself the lion's share of the Euboean contribution. The effect of this money in altering the opinions of the naval officers was marvelous. A new council was called, the former decision was annulled, and the Greeks determined to give their enemies battle where they were.
