When Ramirus, King of Spain, had been fighting a long time against the Saracens, he retired with his soldiers to a mountain to implore the assistance of Almighty God. While he was at prayer, St. James the Apostle appeared to him and commanded him to make all his soldiers go to Confession and Communion the day following and then to lead them out against their enemies. After all had been done that the Saint commanded, they again had an engagement with the Saracens and gained a complete and brilliant victory.
