Minho River
After the victories of Wallia in the campaigns of 416 and 418, the defeated Alans and Silingi Vandals took refuge with the Hasdingi Vandals who were established in the coastal areas of Gallaecia, north of the Minho River. The Vandals, needing new territories to place their newly acquired populations, expanded to the south and blocked their neighbors, the Suebi at the Battle of the Nervasos Mountains of 419.
