Stilicho

Stilicho withdrew Roman legions from Britain to defend Italy against barbarian invasions. This withdrawal weakened Roman control over Britain and contributed to the eventual abandonment of the province by the Roman Empire.

Stilicho defeated the Visigoths under Alaric I at the Battle of Pollentia (modern Pollenzo). The victory forced Alaric to retreat from Italy, temporarily saving the Western Roman Empire from Gothic invasion.

Stilicho again defeated Alaric at the Battle of Verona, forcing the Visigoths to withdraw from Italy. Stilicho negotiated a treaty with Alaric, allowing the Visigoths to settle in Illyricum, a decision that later proved controversial.

Stilicho defeated a large invasion force of Goths under Radagaisus at Fiesole (modern Florence). Radagaisus was captured and executed, and his followers were enslaved or recruited into the Roman army.

Stilicho was executed on the orders of Emperor Honorius, following accusations of treason and conspiracy with the barbarians. His death removed the Western Empire's most capable general and led to a breakdown of Roman defenses.
