Historian A.D. Lee observes, "Alaric’s return to the north-west Balkans brought only temporary respite to Italy, for in 405 another substantial body of Goths and other barbarians, this time from outside the empire, crossed the middle Danube and advanced into northern Italy, where they plundered the countryside and besieged cities and towns" under their leader Radagaisus. Although the imperial government was struggling to muster enough troops to contain these barbarian invasions, Stilicho managed to stifle the threat posed by the tribes under Radagaisus, when the latter split his forces into three separate groups. Stilicho cornered Radagaisus near Florence and starved the invaders into submission. Meanwhile, Alaric—bestowed with codicils of "magister militum" by Stilicho and now supplied by the West—awaited for one side or the other to incite him to action as Stilicho faced further difficulties from more barbarians.
