Surrender of Dimallum and Issa (219/218 BC)

Unlike Teuta in 229 BC, Demetrius was well prepared for the Roman invasion. He first placed a garrison in Dimallum, an Illyrian city-fortress from Apollonia. He eliminated his opponents in other places, those Illyrians who opposed his rule, and stationed 6,000 of his best forces on his home island of Pharos. As before, both consuls of the year accompanied the Roman expedition, but the leading role was played by Aemilius Paullus, who was to be killed in the great Roman disaster at Cannae three years later. The Adriatic took on particular importance in Rome's preparations for the Second Punic War from 218 to 201 BC. Anticipating a long and difficult war far away from Rome, the RomanThe Roman Republic was a form of government of Rome and the era of the classical Roman civilization when it was run through public representation of the Roman people. Beginning with the overthrow of the Roman Kingdom (traditionally dated to 509 BC) and ending in 27 BC with the establishment of the Roman Empire, Rome's control rapidly expanded during this period - from the city's immediate surroundings to hegemony over the entire Mediterranean world.Roman Senate decided first to set matters right in Illyria.

In 219 BC, having decided that Dimallum was crucial to Demetrius' power in the region, the consul prepared to besiege the city, but was able to take it by direct assault within seven days and went to Pharos. As a result, all the Illyrian towns and cities of the area submitted to Roman protection, each receiving the appropriate terms and conditions. Next, the Romans moved against Demetrius on the island of Pharos, who awaited the attack with good troops, ample provisions and war materials behind strong fortifications, that of the city of Issa at modern Stari Grad. To avoid a long siege, Aemilius decided to risk another frontal attack. The Roman army moved from the mainland to a wooded area of the island. Meanwhile, the next day, a small force of ships was sent out to tempt Demetrius from behind his fortifications. Demetrius marched down to the harbor to oppose the Roman landing. The strategy worked, and when the main Roman army appeared from another direction on the island, the Illyrian army was forced to give battle, as they were cut off from their city. Attacked on two sides, and cut off from the protection of the city walls, the battle was lost. In 218 BC, the Illyrian forces soon surrendered, while Demetrius deserted the island and fled to Macedonia, making his way to the court of Philip V of Macedon, who was now the Macedonian king following the death of Antigonus.

  Second Illyrian War (220-219 BC)

  The Second Illyrian War lasted from 220 BC to 219 BC. In 219 BC, the Roman Republic was at war with the Celts of Cisalpine Gaul, and the Second Punic War with Carthage was beginning. These distractions gave Demetrius the time he needed to build a new Illyrian war fleet. Leading this fleet of 90 ships, Demetrius sailed south of Lissus, violating his earlier treaty and starting the war. Demetrius' fleet first attacked Pylos, where he captured 50 ships after several attempts. View Historic Battle »
