On the fourth day Agesilaus led his troops against Peiraeum, but finding it strongly defended, he made a sudden retrograde march after the morning meal in the direction of the capital, as though he calculated on the betrayal of the city. The Corinthians, in apprehension of some such possible catastrophe, sent to summon Iphicrates with the larger portion of his light infantry. These passed by duly in the night, not unobserved, however, by Agesilaus, who at once turned round at break of day and advanced on Piraeum. He himself kept to the low ground by the hot springs, (4) sending a division to scale the top of the pass. That night he encamped at the hot springs, while the division bivouacked in the open, in possession of the pass. Here Agesilaus distinguished himself by an invention as seasonable as it was simple. Among those who carried provisions for the division not one had thought of bringing fire. The altitude was considerable; there had been a fall of rain and hail towards evening and the temperature was low; besides which, the scaling party were clad in thin garments suited to the summer season. There they sat shivering in the dark, with scarcely heart to attack their suppers, when Agesilaus sent up to them as many as ten porters carrying fire in earthen pots. One found his way up one way, one another, and presently there were many bonfires blazing--magnificently enough, since there was plenty of wood to hand; so that all fell to oiling themselves and many supped over again. The same night the sky was lit up by the blaze of the temple of Poseidon--set on fire no one knows how. (4) Near mod. Lutraki.
