While they remained there an envoy came from Antiochus proposing peace, on condition of his giving up all claim to the Grecian cities in Asia and paying one-half of the expenses of the war. The Scipios insisted on his paying all the expenses of the war, as he had been the cause of it, and evacuating Asia on this side of Mount Taurus. The envoy then applied privately to P. Scipio, telling him that the king would release without ransom his son, who had lately fallen into his hands, and give him a large quantity of gold and every honour he could bestow, if through his means he could obtain more equitable terms. Scipio expressed his gratitude, as a private person, to the king for the offer to release his son; and, as a friend, advised him to accept any terms he could get, as his case was hopeless. The envoy retired; the Romans advanced to Ilium, where the consul ascended and offered sacrifice to Minerva, to the great joy of the Ilienses, who asserted themselves to be the progenitors of the Romans. They thence advanced to the head of the river Caicus. Antiochus, who was at Thyatira, hearing that P. Scipio was lying sick at Elæa, sent his son to him, and received in return his thanks, and his advice not to engage till he had rejoined the army. As in case of defeat his only hopes lay in P. Scipio, he took his counsel, and retiring to the foot of Mount Sipylus formed a strong camp near Magnesia.
The consul advanced, and encamped about four miles off; and as the king seemed not inclined to fight, and the Roman soldiers were full of contempt for the enemy, and clamorous for action, it was resolved, if he did not accept the proffer of battle, to storm his camp. But Antiochus, fearing that the spirit of his men would sink if he declined fighting, led them out when he saw the Romans in array.
The Roman army, consisting of four legions, each of fifty-four hundred men, was drawn up in the usual manner, its left resting on a river; three thousand Achæan and Pergamenian foot were placed on the right, and beyond them the horse, about three thousand in number; sixteen African elephants were stationed in the rear. The army of Antiochus consisted of sixty-two thousand foot, twelve thousand horse, and fifty-four elephants. His phalanx of sixteen thousand men was drawn up in ten divisions, each of fifty men in rank and thirty-two in file, with two elephants in each of the intervals. On the left and right of the phalanx were placed the cavalry, the light troops and the remainder of the elephants, the scythed chariots, and Arab archers, mounted on dromedaries.
When the armies were arrayed, there came on a fog, with a slight kind of rain, which relaxed the bowstrings, slings, and dart thongs of the numerous light troops of the king, and the darkness caused confusion in his long and various line. Eumenes, also, by a proper use of the light troops, frightened the horses of the scythed chariots, and drove them off the field. The Roman horse then charged that of the enemy and put it to flight; the confusion of the left wing extended to the phalangites, who, by their own men rushing from the left among them, were prevented from using their long
All the cities of the coast sent in their submission to the consul, who advanced to Sardis. Antiochus was at this time at Apamea; and when he learned that P. Scipio, who had not been in the battle, was arrived, he sent envoys to treat of peace on any terms. The Romans had already arranged the conditions of peace, and P. Scipio announced them as follows: Antiochus should abstain from Europe, and give up all Asia this side of Taurus; pay fifteen thousand Euboic talents for the expenses of the war, five hundred down, fifteen hundred when the senate and people ratified the peace, the remainder in twelve years, at one thousand talents a year; give Eumenes four hundred talents and a quantity of corn; give twenty hostages; and, above all, deliver up Hannibal, Thoas the Ætolian, and three other Greeks. The king’s envoys went direct to Rome, whither also went Eumenes in person, and embassies from Rhodes and other places; the consul put his troops into winter quarters at Magnesia, Tralles, and Ephesus.
