The king, with a handful of cavaliers, galloped to a rising ground, exposed to the fire of the enemy, calling upon the flying troops and endeavoring in vain to rally them.

Setting upon the Moors, he and his cavaliers charged them so vigorously, that they put a squadron to flight, slaying many with their swords and lances and driving others into the river, where they were drowned.

The Moors, however, were soon reinforced, and returned in great numbers.

The king was in danger of being surrounded, and twice owed his safety to the valor of Don Juan de Ribera, senior of Montemayor.
The marques of Cadiz beheld from a distance the peril of his sovereign.
Summoning about seventy horsemen to follow him, he galloped to the spot, threw himself between the king and the enemy, and, hurling his lance, transpierced one of the most daring of the Moors.

For some time he remained with no other weapon than his sword; his horse was wounded by an arrow and many of his followers were slain; but he succeeded in beating off the Moors and rescuing the king from imminent jeopardy, whom he then prevailed upon to retire to less dangerous ground.
The marques continued throughout the day to expose himself to the repeated assaults of the enemy: he was ever found in the place of the greatest danger, and through his bravery a great part of the army and camp was preserved from destruction.* * Cura de los Palacios, c.
