The ablest of the Athenian generals at this time was Demosthenes, [Footnote: To be carefully distinguished from the great orator, born about forty years after the date reached in this chapter (425 B.C.).] who in the previous year had greatly distinguished himself by a brilliant campaign in Aetolia. In the following summer he obtained permission to take passage on board a fleet which was bound on a voyage to Corcyra and Sicily. He sailed in a private capacity, but he was authorized to use the ships against the coasts of Peloponnesus, if he saw any opening which might be utilized in the interests of Athens. On a rocky promontory, at the northern end of the spacious bay of Navarino, lies the little town of Pylos, generally believed to have been the home of the Homeric Nestor. Since the conquest of Messenia by the Spartans, the town had remained in ruins, and the country for some distance round was a desert. The natural advantages of the adjacent coast had already caught the keen eye of Demosthenes, and he had formed the plan of raising a fortified outpost on the spot, to be held by a picked troop of the banished Messenians, and thus planting a thorn in the side of Sparta. Fortune favoured his design. For on rounding the western headland of Peloponnesus, the fleet encountered a storm, and was compelled to seek shelter at Pylos. Demosthenes now urged the admirals to employ their enforced leisure in fortifying the place. But they repulsed him rudely, and treated his suggestion with contempt. He next tried to interest the inferior officers in his project, but meeting with no better success, he began to fear that this grand opportunity would be thrown away. The discussion, however, had reached the ears of the soldiers, and having nothing else to do, they agreed among themselves to pass the time by building a fort. Choosing a place of great natural strength, where the rocky coast descends abruptly to the open sea, they went to work with a will. As they had no tools for stone-cutting, they picked out the stones, and fitted them together according to their shape; and for want of hods they carried the mortar, wherever it was required, on their backs, stooping forward and clasping their hands together behind them, to prevent it from slipping off. They carried out their self-imposed task with great energy, and after six days of vigorous labour the fort was completed, for the natural defences of the site were so strong that in most places there was no need of a wall. As the weather was now favourable, the fleet proceeded on its voyage, leaving Demosthenes with five ships to garrison the fort.
