The foreigners used to start from Mycale every day and sail up to the Grecian fleet, hoping to induce them to accept the challenge and come forth to a battle; but during the night they used to moor their vessels near Mycale, which was an inconvenient station, because they were under the necessity of fetching water from the mouth of the river Maeander, a great way off.[159] Alexander guarded the harbour of Miletus with his ships, in order to prevent the foreigners from forcing an entrance; and at the same time he sent Philotas to Mycale in command of the cavalry and three regiments of infantry, with instructions to prevent the men in the ships from landing. Accordingly, they, being through the scarcity of fresh water and of the other necessaries of life as good as besieged in their ships, sailed away to Samos; where furnishing themselves with food, they sailed back again to Miletus. They then drew up most of their ships in front of the harbour on the deep sea, with the hope that they might in some way or other induce the Macedonians to come out into the open sea. Five of their ships sailed into the roadstead which lay between the island of Lade and the camp, expecting to surprise Alexander’s ships while empty of their crews; for they had ascertained that the sailors for the most part were dispersed from the ships, some to gather fuel, others to collect provisions, and others being arranged in foraging parties.[160] And indeed it happened that a number of the sailors were absent; but as soon as Alexander observed the five Persian ships sailing towards him, he manned ten ships with the sailors who happened to be at hand, and sent them with all speed against them with orders to attack prow to prow. No sooner did the men in the five Persian ships see the Macedonians bearing up against them, contrary to their expectation, than they immediately tacked about, though far off, and fled to the rest of their fleet. However, the ship of the Iassians,[161] not being a fast sailer, was captured in the flight, men and all; but the other four succeeded in escaping to their own triremes. After this the Persians sailed away from Miletus without effecting anything. CHAPTER XX. SIEGE OF HALICARNASSUS.—ABORTIVE ATTACK ON MYNDUS.
