Alexander, pleased with the readiness of the reply, kept his oath; and of course the city was saved.

In his progress onward, Alexander found himself obliged to cross either Mount Ida, or a river which descended from its slopes, called the Granicus. As they neared the river, some of the Grecian scouts, or as they were called by the Greeks, prodromi, reported that the opposite side was lined with Persian troops, waiting to dispute the passage.

Parmenio counselled Alexander against an immediate crossing, but Alexander was unwilling to delay. Accordingly, the army advanced to the banks in order of battle. The centre portion of the Grecian troops was arranged in a peculiar manner, and was called a phalanx. The men composing it were heavily armed. They bore a shield upon the left arm, and they carried spears sixteen feet long and pointed with iron, which they clasped firmly with both hands, with the points projecting in front. These men were placed in line, one behind another, to the number of sixteen, all facing the enemy. So that a phalanx contained sixteen thousand men. The spears were so long, that when drawn up in close lines, the points of eight or ten of the ranks projected in front, forming a bristling wall of sharp points of steel. This wall no force could penetrate; men, horses, elephants, rushed upon it, only to meet inevitable destruction. If their enemies threw javelins from a distance, the shields upon their arms were held in such a manner as to form a mass of close scales of metal, upon which the javelins fell harmlessly. The troops upon the sides of the phalanx were called the wings, and were composed of cavalry and foot-soldiers, who were more lightly armed, and could therefore move with greater speed.

Alexander commanded one wing, and Parmenio the other. The Persians had assembled in vast numbers upon the opposite shore. The Grecian army, led by Alexander, descended into the stream, and moved on through the water. The Persians dashed down the farther banks, and strove to oppose their landing. A terrible battle ensued, the soldiers grappling with each other in the midst of the waves, and the Granicus ran red with the blood of the wounded. Alexander was fearless and irresistible, and his long white plume, waving from his shining helmet, was a conspicuous target for the arrows and javelins of the enemy. At one time, meeting the foe in close combat, a Persian horseman aimed a blow at his head with a sword. The weapon took off the white plume, and cut into the helmet of Alexander, who immediately stabbed his antagonist through the heart. Just as a second Persian had raised his sword to strike a fatal blow upon the exposed head of the Grecian hero, a Macedonian general cut the uplifted arm from the assailant’s body, and saved the life of Alexander the Great. The Persians were defeated, and Alexander landed his brave band of warriors upon the opposite bank, while the terrified Persians fled in dire confusion.

Darius himself had not commanded this Persian force, and he employed all of the following winter in preparing for a vigorous defence of his dominions from the encroaching foe.

Alexander, however, did not remain idle during the winter. He marched from province to province, meeting with many adventures. During this time Parmenio had remained in the western part of Asia Minor, with quite a large force. As the spring approached, Alexander ordered him to meet him at Gordium. One reason which influenced Alexander in this plan was the desire to attempt to untie the famous Gordian knot. The story of the Gordian knot was this:—

Gordius was a sort of mountain farmer. One day he was plowing, and an eagle flew down and alighted upon his yoke, and remained there until he had finished his plowing. This was an omen; but Gordius did not know what it meant. So he went to a neighboring town to consult the prophets and soothsayers. On his way he met a maiden who was going forth to draw water. Gordius fell into conversation with her, and related to her the occurrence which had just transpired. The maiden advised him to go back and offer a sacrifice to Jupiter. Finally she consented to go back with him and aid him. The affair ended in her becoming his wife, and they lived in peace and happiness for many years upon their farm. They had a son named Midas. The father and mother were accustomed to go out in their wagon drawn by oxen, with Midas as their driver. One day they were going into the town in this manner, at a time when it happened that there was an assembly convened, which was in a state of great perplexity, on account of civil dissensions in the country. They had just inquired of an oracle what they should do. The oracle said that “a cart would bring them a king who would terminate their eternal broils.” Just then Midas came up, driving the cart in which his father and mother were seated. The assembly thought at once that this must be the cart meant by the oracle, and they made Gordius king by acclamation. They took the cart and yoke to preserve as sacred relics, consecrating them to Jupiter, and Gordius tied the yoke to the pole of the cart by a thong of leather, making a knot so close and complicated that nobody could untie it again. It was called the Gordian knot. The oracle afterwards said that whoever should untie this knot should become monarch of all Asia. Thus far, nobody had succeeded.

Alexander was very desirous of examining this wonderful knot and trying his own fortune. He accordingly went into the temple where the sacred cart had been placed, and after looking at the knot, he became convinced that it could not be untied, whereupon he cut it to pieces with his sword.

From this story comes the old saying, when any one gets out of a difficulty by very violent means, “He has cut the Gordian knot.”
