Rome's last gasp began when the Visigoths revolted around 395 AD. Led by Alaric I, they attempted to seize Constantinople, but were rebuffed and instead plundered much of Thrace in northern Greece. In 402 AD they besieged Mediolanum, the capital of Roman Emperor Honorius, defended by Roman Gothic troops. The arrival of the Roman Stilicho and his army forced Alaric to lift his siege and move his army towards Hasta (modern Asti) in western Italy, where Stilicho attacked it at the Battle of Pollentia, capturing Alaric's camp. Stilicho offered to return the prisoners in exchange for the Visigoths returning to Illyricum but upon arriving at Verona, Alaric halted his retreat. Stilicho again attacked at the Battle of Verona and again defeated Alaric, forcing him to withdraw from Italy.
