 Lacking strong-points in central Hispania, Metellus set about creating them, he also started to methodically secure the cities and tribes of Hispania [this was the same strategy his father had used in the Jugurthine War when he had to fight king Jugurtha of Numidia who also used guerrilla tactics – Metellus had served on his father's staff back then].Some of these forts are known today – Metellinum (Medellin), Castra Caecilia (Cáceres), Viccus Caecilius and Caecilina.This strategy might have worked on an inferior opponent, but Sertorius kept up a relentless campaign of hit-and-run attacks and ambuscades slowly wearing down Metellus who was soon forced to call for help.
