conceive how such an answer affected a man of the king's temper. He instantly sent his son with an army into Cappadocia. But once more he tried diplomacy. [Sidenote: Ultimatum of Mithridates.] Pelopidas, his envoy, came to Aquillius, and said that his master was willing to aid the Romans against the Italians if the Romans would forbid Nicomedes to attack him, their ally. If not, he wished the alliance to be formally dissolved. Or there was yet another alternative. Let the commissioners and himself appeal to the Senate to decide between them. The commissioners treated the message as an insult. Mithridates, they said, must not attack Nicomedes, and they intended to restore Ariobarzanes. Possibly the conduct of Aquillius was due to his having been heavily bribed by Nicomedes, who must have felt that when the Romans were gone he would be like a mouse awaiting the cat's spring; for it is difficult to imagine the foolhardiness which without some such tangible stimulus would at that moment have plunged him into war. [Sidenote: War begun. Energy of Mithridates.] But when once the die was cast, Mithridates threw himself into the war with the energy of long-suppressed rage. He sent to court the alliance of Egypt and the Cretan league, to whom he represented himself as the champion of Greece against her tyrant. He tried to stir up revolts in Thrace and Macedonia. He arranged with Tigranes that an Armenian army should co-operate with him, leaving him the land it occupied, but carrying off the plunder. He gave the word, and a swarm of pirate ships swept the Mediterranean under his colours. He summoned an army of 250,000 foot, 40,000 horse, and 130 scythed chariots, a fleet of 300 decked vessels, and 100 other ships called 'Dicrota' with a double bank of oars. He formed and armed in Roman fashion a foreign contingent, in which many Romans and Italians enlisted; and he placed able Greek generals, Archelaus and Neoptolemus, over his troops. [Sidenote: Forces of Rome.] To meet this formidable array the Romans had a fleet off Byzantium, the army of Nicomedes, which was still between Sinope and Amastris, and three corps, each of 40,000 men, but composed for the most part of hastily organized Asiatics; one under Cassius between Bithynia and Galatia, another under Aquillius between Bithynia and Pontus, and a third under Oppius in Cappadocia. The war was decided almost in a single battle. [Sidenote: Victory of Mithridates over Nicomedes.] Neoptolemus and Archelaus routed the Bithynian army on the river Amnias, and captured the camp and military chest. It was a fierce and for some time a doubtful fight, and seems to have been decided by the scythed chariots, which spread terror in the Bithynian ranks. [Sidenote: Victory over Aquillius.] Nicomedes fled to Aquillius, who was defeated by Archelaus near Mount Scorobas, and fled with the king across the Sangarius to Pergamus, whence he attempted to reach Rhodes. Cassius retreated to Phrygia, and tried to discipline
