Down from the Phrygian plateau, through a land that glowed with the touch of autumn, marched the Macedonian host, with Alexander at its head. On a clear October night the army halted at the foot of the rugged and forbidding crags of the Taurus. Leonidas with his cavalry troop followed the young king in the attack upon the Cilician Gates, which scattered the guard stationed there and opened the way into the satrapy of Cilicia.
From one of the captives taken at the pass, Alexander learned that the satrap Arsames had planned to plunder the city of Tarsus and retreat into Syria with his spoil. While the main body of the troops was still filing through the pass, he gathered a chosen body of cavalry and light infantry and swooped like a falcon upon the town. The Spartan rode that day at the head of his squadron for fifty miles; and Arsames, abandoning all thought of plunder, deemed himself fortunate to escape with his garrison.
It was here that Alexander fell ill from bathing in the icy waters of the Cydnus, and the rumor spread through the army that his life was in danger. Grief and anxiety pervaded the camp. The toughest of the veterans, with tears in their eyes, gathered before the house in which he lay, demanding news of his condition. The physicians came and went with grave faces and in silence.
Although his fever ran high, Alexander insisted upon receiving his friends as usual and attending to his affairs. One day came a letter from Parmenio, who had been sent forward with a strong detachment to secure the southern pass into Syria through the Amanic range. The young king read it thoughtfully, and Leonidas noticed that he thrust it under his pillow without discussing its contents as his custom was.
A conference of the physicians was being held to consider the king's malady, for it was evident that some decisive measure must be taken if the fever was to be checked. In this consultation a dispute arose between Philip of Acarnania and the other physicians. Philip maintained that a strong remedy should be given, but when he named the potion that he proposed to administer, his colleagues declared that they would have no part in it, holding the opinion that the drugs would surely kill the patient.
Hearing the voices raised in controversy, Alexander demanded the reason. He called the doctors before him and listened to all they had to say.
"Will this draught of which you speak enable me to ride Bucephalus in three days?" he asked of Philip.
"I will answer for it," the Acarnanian replied.
"Compound it, then, for me," the young king said. "When it is ready, I will take it."
He turned his face away and the physicians left him. During the interval of waiting he talked with Clitus, Philotas, Leonidas, and others of his Companions concerning the Trojan war, but, noting their evident anxiety, he broke off to rally them upon it.
