command of a large Roman army finally arrived, Archelaus and the Pontic army withdrew from Boeotia and pulled back to Athens. They fortified themselves in Piraeus and left Athens to Aristion the Athenian tyrant. Mithridates VI had sent his son Arcathius and a much larger Pontic army to Greece to assist Archelaus. As Arcathius was advancing through Northern Greece, Archelaus made several failed attempts to get supplies into Athens. On March 1, 86 BC, Sulla and his legions finally broke into Athens. By that time, Arcathius had died on his way to Athens. His army however was still intact and pursuing the remnants of the legions of Macedonia. Archelaus’ ally the Athenian tyrant Aristion had escaped into the Acropolis of Athens. Archelaus and his Athenian allies lost control of Piraeus and Athens; they were pushed back to the peninsula of Munichia. Archelaus took the Pontic army and joined the remaining forces in Thessaly, taking command at Thermopylae. Sulla moved to Boeotia to face Archelaus. Their two armies clashed at Battle of Chaeronea in 86 BC, where Archelaus was completely defeated. Archelaus escaped to Chalcis where he received 80,000 reinforcements from Mithridates VI. As Sulla lacked a Roman fleet, Archelaus carried out raids around the Greek coast, even destroying some of Sulla’s transports carrying the advance guard of Sulla’s replacement. Eventually Sulla faced Archelaus at Orchomenus in 86/85 BC. After a two-day battle, Archelaus was decisively defeated by the Romans. After the defeat, he was forced to hide two days in the swamps of Lake Copais, before once again managing to escape to Chalcis. When Mithridates VI heard the news of the disastrous defeats, he ordered Archelaus to make peace with Sulla. On the conclusion of the peace conference between Mithridates VI and Sulla in late 86 BC, Archelaus suggested that Sulla recognise the status quo in Asia and in return Mithridates VI would ally with him against his enemies in Rome. Sulla, who was adept at such negotiations, responded to Archelaus by inviting him to surrender his fleet and become an ally of Rome. The final terms of Sulla were that Mithridates VI should surrender part of the Pontic fleet and all conquered territory in Asia and pay an indemnity of 2,000 talents, in return for becoming a friend and ally of Rome. Archelaus remained with Sulla while these terms were sent to Mithridates VI. Archelaus was beginning to worry
