How about this for un-P.C. This is the patron saint of Galicia, Spain, the land of my ancestors before their move to the New World.
Santiago Matamoro (Saint James the Moor-Killer)
The Muslim Moors conquered all of Spain in 711 A.D. except for the Northwest provinces of Galicia and Asturias. The Reconquista (Reconquest) lasted 781 years until 1492 but, as Keegan notes, perserverance is the Western way of war.
I'm curious: Isn't that where the Basques are concentrated. Then the Moors couldn;t handle them either?
