Following its successive defeats at Cyzicus and Battle of Nicaea in 193, Niger's army successfully withdrew to the Taurus mountains, where it fiercely defended the Cilician pass. At this time, the commander of the Severan troops, Tiberius Claudius Candidus was replaced by Publius Cornelius Anullinus, perhaps due to the failure of the former to prevent the withdrawal of the rival army.
Eventually, Anullinus entered Syria, and the final battle took place in May 194, near Issus, the place where Alexander the Great had defeated the Persian King Darius III in 332 BC. Severus took advantage of the control he had on the lives of the children of the provincial governors, who were left at Rome, and of the rivalries of the cities in the region, thus encouraging governors to change sides, one legion to desert to him, and some cities to revolt.
Severan troops attacked first, while Niger's forces were hurling missiles onto them. According to Dio, Severan legionaries applied testudo, using their shields for protecting either themselves or their own missile shooters (however, it seems that it was not the real testudo that was used in sieges or against highly mobile attackers). At the same time, the Severan cavalry attacked from the rear. The fight was hard, but in the end, Severus won decisively and Niger fled back to Antioch. A sudden thunderstorm played some role in lowering the morale of Niger's troops, who were directly facing it, because they had attributed it to divine intervention.
A triumphal arch was set on site, commemorating the victory of Severus.
While this battle concluded hostilities on the field between the two rivals for control of the East (Niger was captured and killed, a few days later), the city of Byzantium withstood a siege by Severan troops until AD 196, possibly on the hope that a third rival to the principate, the governor of Britain Clodius Albinus, nominally allied with Niger, would defeat Severus in the West. The opposite occurred at the Battle of Lugdunum.
