contemporary sources, Mithridates and a small contingent escaped the battle, outstripped their pursuers, and reached Colchis on the Black Sea. While there, he took control of the Cimmerian Bosporus from its Roman-backed ruler, his son Machares, who later committed suicide. Meanwhile, Pompey invaded Armenia supported by Tigranes the Younger, whose father quickly came to terms; in return for the restoration of Armenian territories taken by Lucullus, he paid a substantial cash indemnity and allowed Roman troops to be based on his territory. In 65 BC, Pompey set out to take Colchis, but to do so had first to subdue various local tribes and allies of Mithridrates. After winning a series of battles, he reached Phasis and linked up with Servilius, admiral of his Euxine fleet, before a fresh revolt in Caucasian Albania forced him to retrace his steps. Victory at the Abas enabled him to impose terms on the Albanians and agree truces with other tribes on the northern side of the Caucasus. Pompey then wintered in Armenia, settling minor border contests and raids between his allies Phraates and Tigranes. Relying on his naval blockade to wear down Mithridates, Pompey spent 64 BC annexing the independent and wealthy cities of Syria, which were incorporated into a new Roman province. In the process, he acquired large amounts of money and prestige, as well as criticism from his opponents in Rome, who argued doing so exceeded his authority. Meanwhile, an ageing Mithridates had been cornered in Panticapaeum by another of his sons, Pharnaces II of Pontus. An attempt to commit suicide by taking poison allegedly failed due to his habit of taking "precautionary antidotes", and he was killed by the rebels. Pharnaces sent his embalmed body to Pompey, in return for which he was granted the Bosporan Kingdom and made an ally of Rome. Re-organisation of the East The final collapse of the Seleucid Empire in 89 BC had allowed Pompey to annex Syria, but the instability it caused continued to affect the region, while Judea to the south was disrupted by the Hasmonean Civil War. In early 63 BC, he left Antioch and marched south, reducing coastal cities like Apamea which had used the power vacuum to achieve independence. He then crossed the Anti-Lebanon Mountains, captured Pella, Jordan and reached Damascus, completing the occupation of Syria. The two brothers involved in the Judean civil war, Aristobulus II and Hyrcanus II, both
