calls his "considerable qualities [and] considerable luck" to survive. Theodosius was in his 40s, had been emperor for 11 years, had temporarily settled the Gothic wars, and won a civil war. As a Latin speaking Nicene western leader of the Greek largely Arian East, Boniface Ramsey says he had already left an indelible mark on history. McLynn asserts that the relationship between Theodosius and Ambrose transformed into myth within a generation of their deaths. He also observes that the documents revealing the relationship between these two formidable men do not show the personal friendship the legends portray. Instead, those documents read more as negotiations between the institutions the men represent: the Roman state and the Italian Church. Second civil war: 392–394 In 391, Theodosius left his trusted general Arbogast, who had served in the Balkans after Adrianople, to be magister militum for the Western emperor Valentinian II, while Theodosius attempted to rule the entire empire from Constantinople. On 15 May 392, Valentinian II died at Vienna in Gaul (Vienne), either by suicide or as part of a plot by Arbogast. Valentinian had quarrelled publicly with Arbogast, and was found hanged in his room. Arbogast announced that this had been a suicide. Stephen Williams asserts that Valentinian's death left Arbogast in "an untenable position". He had to carry on governing without the ability to issue edicts and rescripts from a legitimate acclaimed emperor. Arbogast was unable to assume the role of emperor himself because of his non-Roman background. Instead, on 22 August 392, Arbogast had Valentinian's master of correspondence, Eugenius, proclaimed emperor in the West at Lugdunum. At least two embassies went to Theodosius to explain events, one of them Christian in make-up, but they received ambivalent replies, and were sent home without achieving their goals. Theodosius raised his second son Honorius to emperor on 23 January 393, implying the illegality of Eugenius' rule. Williams and Friell say that by the spring of 393, the split was complete, and "in April Arbogast and Eugenius at last moved into Italy without resistance". Flavianus, the praetorian prefect of Italy whom Theodosius had appointed, defected to their side. Through early 394, both sides prepared for war. Theodosius gathered a large army, including the Goths whom he had settled in the eastern empire as foederati, and Caucasian and Saracen auxiliaries, and marched against Eugenius. The battle began on 5 September 394, with Theodosius' full frontal
