Battle of Pharos

The Battle of Pharos was a naval battle between the Greek colony Pharos allied with Dionysius the Elder of Syracuse and the the Illyrian Liburnians, which took place in 383/4 BC.The Illyrians of Zadar, the Iadasinoi, became allies of the natives of Hvar and the leaders of an eastern Adriatic coast coalition in the fight against the Greek colonizers. An expedition of 10,000 men in 300 ships sailed out from Zadar and laid siege to the Greek colony Pharos in the island of Hvar, but the Syracusan fleet of Dionysus was alerted and attacked the siege fleet. The naval victory went to the Greeks which allowed them relatively safer further colonization in the southern Adriatic.

Background
The fall of Liburnian domination in the Adriatic Sea and their final retreat to their ethnic region (Liburnia) were caused by the military and political activities of Dionysius the Elder of Syracuse. The imperial power base of this Syracusan tyrant stemmed from a huge naval fleet of 300 tetreras and penteras. After he ended Carthaginian authority in Sicily, he turned against the Etruscans. He made use of the Celtic invasion of Italy, and the Celts became his allies in the Italian peninsula (386 - 385 BC). This alliance was crucial for his politics, then focusing on the Adriatic Sea, where the Liburnians still dominated. In light of this strategy, he established a few Syracusan colonies on the coasts of the Adriatic Sea: Adria at the mouth of Po river and Ancona at the western Adriatic coast, Issa on the outermost island of the central Adriatic archipelago (island of Vis) and others. Meanwhile in 385-384 BC he helped colonists from the Greek island of Paros to establish Pharos (Starigrad) colony on the Liburnian island of Hvar, thus taking control of the important points and navigable routes in the southern, central and northern Adriatic.

Battle
This caused a simultaneous Liburnian resistance on both coasts, whether in their ethnic domain or on the western coast, where their possessions or interests were in danger. The naval battle of Pharos was recorded a year after the establishment of the colony, by a Greek inscription in Pharos (384 – 383 BC) and by the Greek historian Diodorus Siculus (80 – 29 BC); initiated by conflicts between the Greek colonists and the indigenous Hvar islanders, who asked their compatriots for support. 10,000 Liburnians sailed out from their capital Idassa (Zadar), led by the Iadasinoi (people of Zadar), and laid siege to Pharos. The Syracusan fleet positioned in Issa was informed in time, and Greek triremes attacked the siege fleet, taking victory in the end. According to Diodorus, the Greeks killed more than 5,000 and captured 2,000 prisoners, ran down or captured their ships, and burned their weapons in dedication to their god.

Diodorus (15.14) records the following:

''This year the Parians who had settled on Pharos allowed the previous barbarian inhabitants to remain unharmed in a well fortified place, while they themselves built their city by the sea and enclosed it with a wall. Later the earlier inhabitants took offence at the presence of the Greeks and called in the Illyrians dwelling on the mainland opposite. These crossed to Pharos in a large number of small boats and, more than en thousand strong, killed many Greeks and did much damage. However Dionysius' commander at Lissus sailed up with a large number of Triremes against the Illyrian light craft and, having sunk some and captured others, killed more than five thousand of the barbarians and took around two thousand prisoners. ''

Aftermath
This battle meant the loss of the most important strategic Liburnian positions in the centre of the Adriatic, resulting in their final retreat to their main ethnic region, Liburnia, and their complete departure from the Italic coast, apart from Truentum (nowadays on the border between Marche and Abruzzo). Greek colonization, however, did not extend into Liburnia, which remained strongly held, and Syracusan dominance suddenly diminished upon the death of Dionysius the Elder.
