Xeres (Moslem Empire in Spain).
Fought July 19 to 26, 711, between 90,000 Spaniards, under Roderic, and 12,000 Moslems, with a numerous force of African auxiliaries, under Tarik. On the fourth day the Moslems suffered a severe repulse, leaving 16,000 dead on the field, but the defection of Count Julian, with a large part of the King's forces, revived their courage, and finally the Christians were routed and dispersed. Roderic fled from the field, but was drowned in crossing the Guadalquivir. This victory marks the fall of the Gothic monarchy, and the beginning of the Moorish domination in Spain.
