The Greek chiefs, nothing daunted by the words of Calchas, now set sail with their immense fleet. Though the war was to be a long one, they were encouraged by the prophecy that they were to be the conquerors.

Their first experience was not very fortunate. They safely crossed the Ægean Sea, but instead of steering for Troy, the pilots, through either ignorance or mistake, brought the vessels to the shore on the coast of Teu-thra'ni-a, a district in the kingdom of Mys'i-a, lying southeast of Troas. Here the Greeks landed, but they were at once attacked by Tel'e-phus, the king of that country, who came down upon them with a strong force, and drove them back to their ships after a battle in which many of them were killed. They would probably have fared much worse had it not been for the friendly aid of Bacʹchus, the god of wine. While Telephus was fighting at the head of his men he tripped and fell over a vine, which the god had caused to spring up suddenly from the earth at his feet. As he lay flat on the ground Achilles rushed forward and severely wounded him with a thrust of his spear.

The Greeks, however, were obliged to take to the sea, and soon afterward a great storm arose, which destroyed many of their vessels. Owing to this misfortune they had to return to Aulis, where they set about repairing their damaged ships and getting ready to start again. While the Greeks were thus engaged, they were surprised by the appearance of King Telephus, who came to their camp to beg Achilles to cure his wound, an oracle he had consulted having told him that he could be cured only by the person who had wounded him.

Achilles was at first unwilling to comply with the request of Telephus, but Ulysses advised him to do so. Telephus was one of the sons of Hercules, and it had been decreed that without the help of a son of that hero Troy could not be taken. Moreover, he was a son-in-law of Priam, and his country lay close to where the war was to be carried on. For these reasons Ulysses wished to make him friendly to the Greeks, and so he persuaded Achilles to cure the Teuthranian king. Achilles did this by dropping into the wound portions of the rust from the point of his spear. Telephus was so grateful that he joined the expedition against Troy, and undertook to pilot the Grecian fleet to the Trojan coast.

But another difficulty now stood in the way of the Greeks. Their fleet was once more ready for departure, but the winds were unfavorable. In ancient times they could not make a sea voyage when the winds were against them. Their ships were very small, and were moved only by oars and sails. Homer gives us a good idea of the ancient system of navigation, where he tells, in the Odyssey, about young Telemachus setting out on a voyage in search of his father, Ulysses:

Telemachus went up
The vessel's side, but Pallas first embarked,
And at the stern sat down, while next to her
Telemachus was seated. Then the crew
Cast loose the fastenings and went all on board,
And took their places on the rowers' seats,
While blue-eyed Pallas sent a favoring breeze,
A fresh wind from the west, that murmuring swept
The dark-blue main. Telemachus gave forth
The word to wield the tackle; they obeyed,
And raised the fir-tree mast, and, fitting it
Into its socket, bound it fast with cords,
And drew and spread with firmly twisted ropes
The shining sails on high. The steady wind
Swelled out the canvas in the midst; the ship
Moved on, the dark sea roaring round her keel,
As swiftly through the waves she cleft her way.

Bryant, Odyssey, Book II.

For many days the Greek chiefs at Aulis waited for favoring breezes, but none came.

"The troops
Collected and embodied, here we sit
Inactive, and from Aulis wish to sail
In vain."

Euripides (Potter's tr.).
