The battle was fought on the 30th of August with great fury and obstinacy on both sides. The Portuguese had strewed, early in the morning, all the front of their line with gun-powder, to which, on the approach of the Turks, they set fire by trains, which burnt and disabled, a great many of them; and things bore a prosperous appearance, till the Moorish general ordered some artillery to be pointed against the Abyssinians, who, upon hearing the first explosion, and seeing the effect of some balls that had lighted among them, fled, and left the Portuguese to the number only of 400, who were immediately surrounded by the Moorish army. Nor did Gragnè pursue the fugitives, his affair being with the Portuguese, the smallness of whose number promised they would fall an easy and certain sacrifice. He therefore, attacked their camp upon every side with very little success, having lost most of his best officers, till, unfortunately, Don Christopher, fighting and exposing himself everywhere, was singled out by a Turkish soldier, and shot through the arm. Upon this all his men turned their thoughts from their own preservation to that of their general, who obstinately refused to fly, till he was by force put upon a litter, and sent off, together with the patriarch and queen.
Night now coming on, Don Christopher had got into a wood in which there was a cave. There he ordered himself to be set down to have his wounds dressed; which, being done, he was urged by the queen and patriarch to continue his flight. But he had formed his resolution, and, without deigning to give his reasons, he obstinately refused to retreat a step farther. In vain the queen, and those that knew the country, told him he was just in the tract of the Moorish horsemen, who would not fail soon to surround him. He repeated his resolution of staying there with such a degree of firmness, that the queen and patriarch, who had no great desire for martyrdom, left him to his fate, which presently overtook him.
In one of Don Christopher’s expeditions to the mountains, he had taken a very beautiful woman, wife to a Turkish officer, whom he had slain. This lady had made a shew of conversion to Christianity; lived with him afterwards, and was treated by him with the utmost tenderness. It was said, that, after he was wounded and began to fly, this woman had given him his route, and promised to overtake him with friends that would carry him to a place of safety. Accordingly, some servants left by the queen, hidden among the rocks, to watch what might befal him, and assist him if possible, saw a woman, in the dawn of the morning, come to the cave, and return into the wood immediately, whence there rushed out a body of Moorish horse, who went straight to the cave and found Don Christopher lying upon the ground sorely wounded. Upon the first question that was asked him, he declared his name, which so overjoyed the Moors, that they gave over further pursuit, and returned with the prisoner they had taken. Don Christopher was brought into the presence of the Moorish general, Gragnè, who loaded him with reproaches; to which he replied with such a share of invectives, that the Moor, in the violence of his passion, drew his sword and cut off his head with his own hand. His head was sent to Constantinople, and parts of his body to Zibid and other quarters of Arabia.
