After Don Alfonso had come forward from the rear and a troop had been formed, Don Alvar went from side to side giving everyone all possible encouragement and making them lose their fear. Then they rode forward, with everyone shouting in unison. 'St James!', and at times 'Castile!'. They began to pierce the Moorish ranks, shattering the first, then the second and third, and then all one after the other, killing and rolling back the enemy and causing great loss of life. Then they started to fight to each side, the Moors being unable to make any sort of stand. It was said - and the Moors themselves averred the same afterwards - that St James appeared there on a white horse with a white banner in one hand and a sword in the other, together with a regiment of knights dressed in white; also that angels were seen to fly through the air above them; and that it seemed as though these white knights were causing greater havoc than any other body of men. Many of the Christians saw this vision too. Then the Moors began to scatter and flee, turning their backs as quickly as they could and confessing defeat. The Christians started to pursue them, killing some and capturing others. The slaughter was so great, that the infantry in their pursuit could not go forward after a time because they found the piles of the dead an obstacle to their progress. Eventually the Christians forced the enemy back against the gates of Jerez, where the slaughter was also very great: the press of men was so tight in the gateway, and so few were able to enter compared with the huge mass that they formed that they were killing each other. What more can one say? Our men whittled them down as a carpenter whittles a beam of wood, and the Moors offered no kind of defence. The field was quickly cleared of them, some being dead, others prisoners, the rest fugitives. In the fray the leader of the Gazuls was killed, together with many other Moors of high rank. The text we are following says, in confirmation of what was stated by those present, that the new knight Garci Ferez de Vargas, whom Alvar Perez had knighted before battle was joined, did himself honour at the start of his career, for it was he who unhorsed and killed that leader of the Gazuls. He it was who had come up with the 700 Arab horsemen mentioned earlier; and even though our text calls them 'Arabs', they were earlier and still at that time called ‘Gazuls', and on account of that name the man was called 'leader of the Gazuls'. He had come from overseas as it were on pilgrimage, in Muhammad's service. When he arrived in al-Andalus, Ibn Hud gave him Alcala, the one now known as 'Alcala de los Gazules' [province of Cadiz]. Ibn Hud, not daring to stay in Jerez while the Christians were so strongly on the attack, made his way to the coast with as many men as he had, and set sail for a place of safety. Who could ever manage to tell how great was the booty taken that day, and the extent of the favours which God heaped upon the Christians? Our men began to search the battlefield, and found so much lying about that they wearied of picking it up. As for what they found in the tents, it was uncountable and beyond any man's reckoning. After they had searched the field they began on the Moorish tents, and found them so richly stocked that they had no need to send elsewhere for what they needed; and it is said that while they remained there they had all the wood they needed for their fires from the shafts of shattered lances. And the nooses and the gallows which had been prepared for them were filled with the bodies of the Moors who had made them. [. . . ]
