The expedition to the Graeco-Illyrian peninsula was designed partly to reduce to subjection or at least to tame the barbarous tribes who ranged over the whole interior from the Black Sea to the Adriatic, and of whom the Bessi (in the great Balkan) especially were, as it was then said, notorious as robbers even among a race of robbers; partly to destroy the corsairs in their haunts, especially along the Dalmatian coast. As usual, the attack took place simultaneously from Dalmatia and from Macedonia, in which province an army of five legions was assembled for the purpose. In Dalmatia the former praetor Gaius Cosconius held the command, marched through the country in all directions, and took by storm the fortress of Salona after a two years' siege. In Macedonia the proconsul Appius Claudius (676-678) first attempted along the Macedono-Thracian frontier to make himself master of the mountain districts on the left bank of the Karasu. On both sides the war was conducted with savage ferocity; the Thracians destroyed the townships which they took and massacred their captives, and the Romans returned like for like. But no results of importance were attained; the toilsome marches and the constant conflicts with the numerous and brave inhabitants of the mountains decimated the army to no purpose; the general himself sickened and died. His successor, Gaius Scribonius Curio (679-681), was induced by various obstacles, and particularly by a not inconsiderable military revolt, to desist from the difficult expedition against the Thracians, and to turn himself instead to the northern frontier of Macedonia, where he subdued the weaker Dardani (in Servia) and reached as far as the Danube. The brave and able Marcus Lucullus (682, 683) was the first who again advanced eastward, defeated the Bessi in their mountains, took their capital Uscudama (Adrianople), and compelled them to submit to the Roman supremacy. Sadalas king of the Odrysians, and the Greek towns on the east coast to the north and south of the Balkan chain--Istropolis, Tomi, Callatis, Odessus (near Varna), Mesembria, and others--became dependent on the Romans. Thrace, of which the Romans had hitherto held little more than the Attalic possessions on the Chersonese, now became a portion--though far from obedient--of the province of Macedonia. Piracy
