Although Sulla was then appointed to deal with Mithridates, events moved very slowly. However, worse was to come later in 88 BC. the 'Asiatic (or 'Ephesian') Vespers', was the slaughter of tens of thousands of Romans and Italians ordered by Mithridates. Having cleansed Asia Minor of Romans, Mithridates looked further afield, his next victim that year being Rhodes, but it held out, and he moved on to the Aegean islands, taking Delos. A number of mainland Greek states welcomed the advance of the Pontian monarch, Sulla not having set out for Greece from Italy until 87 BC. Meanwhile, Mithridates had overcome the Roman army in Macedonia. When the two armies finally met, Sulla inflicted two defeats on the Pontic forces at the battles of Chaeronea (86 BC) and Orchomenus (85 BC) restoring Roman rule to Greece. Pontus sued for peace, faced with widespread revolts in Anatolia. Mithridates was to give up Asia and Paphlagonia, to hand back Bithynia to Nicomedes and Cappadocia to Ariobarzanes. In return he was allowed to continue ruling in Pontus as an ally of Rome, having abandoned all territories south and west of the Halys.
