=173.= A fleet bound for Sicily, under Eurymedon and Sophocles, had been delayed for a time by a storm, near the harbor of Pylos. The commanders selected this place for a settlement of Messenians from Naupactus, who would thus be able to communicate with their Helot kinsmen, and harass the Spartans. Demosthenes was left with five ships and two hundred soldiers, who were increased, by a reinforcement of Messenians, to a thousand men. The wrath of the Spartans was only equaled by their alarm at this infringement of their territory. Their fleet was instantly ordered from Corcyra, while Agis, with his army, marched from Attica. The long and narrow island of Sphacte´ria, which covered the entrance to the Bay of Pylos, was occupied by Thrasymel´idas, the Spartan, while his ships were sheltered in the basin which it inclosed. Demosthenes, while awaiting reinforcements, had to meet a vastly superior number with his handful of men. The attack from the sea was led by Bras´idas, one of the greatest captains whom Sparta ever produced. He fought on the prow of the foremost vessel, urging his men forward by looks and words; but he was severely wounded, and the battle ended with no advantage to the Spartans. It was renewed the second day with no better success, and the Athenians erected a trophy, which they ornamented with the shield of Brasidas.
The arrival of the Athenian fleet was followed by a severe and still more decisive battle. The victorious Athenians proceeded to blockade Sphacteria, which contained the choicest Peloponnesian troops. So serious was the crisis, that the ephors saw no escape except to sue for peace. An armistice was agreed upon, and the better spirits on both sides began to hope for a termination of the war. But the foolish vanity of Cleon and his party demanded the most extravagant terms, and the voice of reason was drowned. Hostilities re-commenced, with equal vexation to both parties. Demosthenes, fearing that the storms of winter would interrupt his blockade, resolved to make an attack upon the island, and sent to Athens explaining his position and demanding reinforcements. The report was disheartening to the Assembly, which now began to accuse Cleon for having persuaded it to let slip the occasion for an honorable peace. Cleon retorted by accusing the officers of cowardice and incapacity, and declared that, if _he_ were general, he would take Sphacteria at once! At this boast of the tanner, the whole assembly broke out into laughter, and cries, “Why don’t you go, then?” were heard on all sides. The lively spirits of the Athenians recovered with a bound from their unusual depression, and the mere joke soon grew into a purpose. Cleon tried to draw back, but the Assembly insisted. At last he engaged, with a certain number of auxiliaries added to the troops already at Pylos, to take the island in twenty days, and either kill all the Spartans upon it, or bring them in chains to Athens.
