with Alamanni and Franks, even marching to the Rhine frontier, where he impressed and pacified the Germanic tribes by parading his army in front of them. After this display, he recruited Alamannic and Frankish units for his army. Fall After his election as emperor, Eugenius sent two embassies to Theodosius's court, asking for recognition of his election. Theodosius received them, but both embassies were given vague responses and returned without completing their missions. In January 393, Theodosius promoted his eight-year-old son Honorius to the rank of Augustus of the West, giving the indication of the illegality of Eugenius' elevation. Following the news of Honorius' elevation to Augustus, Eugenius and Arbogast marched their army, stripped from the Rhine frontier, into Italy in the spring of 393. Theodosius then moved from Constantinople with his army, and met Eugenius and Arbogast at the Battle of the Frigidus in the Vipava Valley, on 6 September 394. The bloody battle lasted two days, and was marked by unusually strong winds, but in the end Theodosius won. Eugenius was captured and then executed, his head afterward being displayed in Theodosius' camp. Arbogast committed suicide the next day.
