, had continued the imperial policy of suppressing Pagan interests over those of the Christians. Not surprisingly, this policy had resulted in increasing tensions between the emperor and the Pagan senators.

When the Eastern Emperor Theodosius heard the news of Valentinian's death, Arbogastes, who was the magister militum and de facto ruler of Western Empire, informed him that the young emperor had committed suicide.

Tensions between the two halves of the empire were heightened further that summer. Arbogastes made several attempts to contact Theodosius, but apparently none got further than the ears of the Eastern praetorian prefect RufinusRufinus (Byzantine official)

. The responses that Arbogast received from Rufinus were unhelpful. Theodosius himself was slowly coming around to the belief Valentinian had been murdered, in no small part because his wife Galla was convinced her brother's death was caused by treachery.

For his part, Arbogast had few friends in the Eastern court, although his uncle RichomeresRichomeres

After his elevation to emperor, Eugenius appointed several important pagan senators to key positions in the Western government.

 and did little to endear him to Theodosius.

As a Christian, Theodosius was distressed by the pagan revival that was occurring under Eugenius's reign. In addition there was the issue of Valentinian's death, which had never been resolved to his satisfaction. Furthermore, Eugenius had removed all the high civil officers left by Theodosius when he had given the Western half of the empire to Valentinian, so that Theodosius had lost his control on the Western Roman Empire.

When a party of Western ambassadors arrived in Constantinople to request that Eugenius be acknowledged as the Western Augustus, Theodosius was noncommittal, even if he received them with presents and vague promises. Whether he had already decided on an offensive against Eugenius and Arbogast at this point is unclear. In the end, however, after declaring his two-years-old son HonoriusHonorius (emperor)

The battle

Theodosius attacked almost immediately, having undertaken little to no prior reconnaissance of the field of battle. He committed his Gothic allies to action first, perhaps hoping to thin their ranks through attrition and lessen their potential threat to the Empire. The Eastern army's headlong attack resulted in heavy casualties but little gain, and the Georgian general Bacurius was among the dead.

Day's end saw Eugenius celebrating his troops' successful defense of their position while Arbogast sent out detachments to close off the mountain passes behind Theodosius's forces.

After a sleepless night, Theodosius was cheered by the news that the men Arbogast had sent to bottle him up in the valley intended to desert to his side. Buoyed by this favorable development, Theodosius's men attacked once again. This time nature was on their side as a fierce tempest — apparently the BoraBora (wind)

...
, a regular occurrence in the region — blew along the valley from the east. The high winds blew clouds of dust into the faces of the Western troops (legend also says, that the fierce winds even blew the Western troops' own arrows back at them). Buffeted by the winds, Arbogast's lines broke and Theodosius gained the decisive victory that the Egyptian monk had prophesied.

In the aftermath, Eugenius was captured and brought before the emperor. His pleas for mercy went unanswered and he was beheaded. Arbogast escaped the defeat and fled into the mountains, but after a few days' wandering, he concluded escape was impossible and committed suicide.

Aftermath

It had been a costly but total victory for Theodosius, and a total loss for the pagans. The western provinces quickly submitted to Theodosius, who became the last emperor of a united empire.

Most significantly, the battle was the last attempt to contest the Christianization of the empire: its outcome decided the fate of Christianity in the western Empire. The battle is on a par with the Battle of the Milvian Bridge in importance, for it was seen not only as a victory in a civil war, but a vindication of the Christian God and the triumph of Christianity - within a generation the elite pagan families of Rome would give up any serious resistance to Christianity and re-invent themselves as the papal families of Late AntiquityLate Antiquity

.

Unfortunately, the battle also accelerated the collapse of the Roman army in the west. The legions were already losing their effectiveness, due to reorganizations and a decline in the quality of their training and discipline, and the losses at the Battle of the Frigidus weakened the western legions — whose task in defending the empire from the barbarian invaders was much harder than the eastern ones — still further. This downturn in the capabilities of the Roman soldiers meant an increasing reliance by the Western Empire on barbarian mercenaries employed as foederatiFoederati
