History of the Peloponnesian War

But before the fleet, gone into the Crisaean gulf and to Corinth, was dispersed, Cnemus and Brasidas and the rest of the commanders of the Peloponnesians in the beginning of winter instructed by the Megareans thought good to make an attempt upon Peiraeus, the haven of the Athenians. Now it was without guard or bar, and that upon very good cause, considering how much they exceeded others in the power of their navy.

And it was resolved that every mariner with his oar, his cushion, and one thong for his oar to turn in should take his way by land from Corinth to the other sea that lieth to Athens and, going with all speed to Megara, launch forty galleys out of Nisaea, the arsenal of the Megareans, which then were there, and sail presently into Peiraeus.

For at that time there neither stood any galleys for a watch before it, nor was there any imagination that the enemies would on such a sudden come upon them; for they durst not have attempted it openly, though with leisure; nor if they had had any such intention, could it but have been discovered.

As soon as it was resolved on, they set presently forward and, arriving by night, launched the said galleys of Nisaea and set sail, not now towards Peiraeus, as they intended, fearing the danger (and a wind was also said to have risen that hindered them), but toward a promontory of Salamis lying out towards Megara. Now there was in it a little fort, and underneath in the sea lay three galleys that kept watch to hinder the importation and exportation of anything to or from the Megareans. This fort they assaulted, and the galleys they towed empty away after them and, being come upon the Salaminians unawares, wasted also other parts of the island.

By this time the fires signifying the coming of enemies were lifted up towards Athens and affrighted them more than anything that had happened in all this war. For they in the city thought the enemies had been already in Peiraeus, and they in Peiraeus thought the city of the Salaminians had been already taken and that the enemy would instantly come into Peiraeus, which, had they not been afraid nor been hindered by the wind, they might also easily have done.

But the Athenians, as soon as it was day, came with the whole strength of the city into Peiraeus and launched their galleys and embarking in haste and tumult set sail toward Salamis, leaving for the guard of Peiraeus an army of foot.

The Peloponnesians upon notice of these succours, having now overrun most of Salamis and taken many prisoners and much other booty besides the three galleys from the fort of Budorus, went back in all haste to Nisaea. And somewhat they feared the more for that their galleys had lain long in the water and were subject to leaking. And when they came to Megara, they went thence to Corinth again by land.
