In the process of time King Ramiro died, and was succeeded by his son Ordoño III., the same who had married Urraca, the daughter of Count Fernan. He was surnamed the Fierce, either from his savage temper or savage aspect. He had a step-brother named Don Sancho, nephew, by the mother’s side, of King Garcia of Navarre, surnamed the Trembler. This Don Sancho rose in arms against Ordoño at the very outset of his reign, seeking to deprive him of his crown. He applied for assistance to his uncle Garcia and to Count Fernan Gonzalez, and it is said both favored his pretensions. Nay, the count soon appeared in the field in company with King Garcia the Trembler, in support of Prince Sancho. It may seem strange that he should take up arms against his own son-in-law; and so it certainly appeared to Ordoño III., for he was so incensed against the count that he repudiated his wife Urraca and sent her back to her father, telling him that since he would not acknowledge him as king, he should not have him for son-in-law. The kingdom now became a prey to civil wars; the restless part of the subjects of King Ordoño rose in rebellion, and everything was in confusion. King Ordoño succeeded, however, in quelling the rebellion, and defended himself so ably against King Garcia and Count Fernan Gonzalez, that they returned home without effecting their object. About this time, say the records of Compostella, the sinful dissensions of the Christians brought on them a visible and awful scourge from Heaven. A great flame, or, as it were, a cloud of fire, passed throughout the land, burning towns, destroying men and beasts, and spreading horror and devastation even over the sea. It passed over Zamora, consuming a great part of the place; it scorched Castro Xerez likewise, and Brebiesco and Pan Corvo in its progress, and in Burgos one hundred houses were consumed. “These,” says the worthy Agapida, “were fiery tokens of the displeasure of Heaven at the sinful conduct of the Christians in warring upon each other, instead of joining their arms like brethren in the righteous endeavor to extirpate the vile sect of Mahomet.” While the Christians were thus fighting among themselves, the Moors, taking advantage of their discord, came with a great army, and made an incursion into Castile as far as Burgos. King Ordoño and Count Fernan Gonzalez, alarmed at the common danger, came to a reconciliation, and took arms together against the Moors; though it does not appear that the king received again his repudiated wife Urraca. These confederate princes gave the Moors a great battle near to San Estevan. “This battle,” says Fray Antonio Agapida, “is chiefly memorable for a miracle which occurred there,” and which is recorded by the good friar with an unction and perfect credence worthy of a monkish chronicler.
