On the following day, the two armies remained regarding each other with wary but menacing aspect. About noontide, King Roderick sent forth a chosen force of five hundred horse and two hundred foot, the best armed of his host, to skirmish with the enemy, that, by gaining some partial advantage, they might raise the spirits of the army. They were led on by Theodomir, the same Gothic noble who had signalised himself by first opposing the invasion of the Moslems. The Christian squadrons paraded with flying pennons in the valley which lay between the armies. The Arabs were not slow in answering their defiance. A large body of horsemen sallied forth to the encounter, together with three hundred of the followers of Count Julian. There was hot skirmishing about the field, and on the banks of the river; many gallant feats were displayed on either side, and many valiant warriors were slain. As the night closed in, the trumpets from either camp summoned the troops to retire from the combat. In this day's action the Christians suffered greatly in the loss of their distinguished cavaliers; for it is the noblest spirits who venture most, and lay themselves open to danger; and the Moslem soldiers had instructions to single out the leaders of the adverse host. All this is said to have been devised by the perfidious Bishop Oppas, who had secret communications with the enemy, while he influenced the councils of the king; and who trusted that by this skirmishing warfare the power of the Christian troops would be cut off, and the rest disheartened.
