We next hear of Sarus in 410, apparently subsisting independently in the region of Picenum. Athaulf, who was coming to join his brother-in-law Alaric, decided to attack him in passing and Sarus, thinking his force of three hundred would be no match for the Gothic army, fled to Honorius. Later that year, when Alaric was conducting negotiations with Honorius near Ravenna, Sarus with his warband attacked him, seemingly on his own initiative. This prompted Alaric to finally give up on negotiations and sack Rome on August 24.
