Ogier recognized the standard of his friend, and leaping upon Marchevallee, flew to aid his attack.  Charlemagne followed with his army; and the Saracen host, after an obstinate conflict, was forced to surrender unconditionally.

The interview of Ogier and Carahue was such as might be anticipated of two such attached friends and accomplished knights.  Charlemagne went to meet them, embraced them, and putting the King of Mauritania on his right and Ogier on his left, returned with triumph to Paris.  There the Empress Bertha and the ladies of her court crowned them with laurels, and the sage and gallant Eginhard, chamberlain and secretary of the Emperor, wrote all these great events in his history.

A few days after Guyon, King of Denmark, arrived in France with a chosen band of knights, and sent an ambassador to Charlemagne, to say that he came, not as an enemy, but to render homage to him as the best knight of the time and the head of the Christian world.  Charlemagne gave the ambassador a cordial reception, and mounting his horse, rode forward to meet the King of Denmark.

These great princes, being assembled at the court of Charles, held council together, and the ancient and sage barons were called to join it.

It was decided that the united Danish and Mauritanian armies should cross the sea and carry the war to the country of the Saracens, and that a thousand French knights should range themselves under the banner of Ogier, the Dane, who, though not a king, should have equal rank with the two others.

We have not space to record all the illustrious actions performed by Ogier and his allies in this war.  Suffice it to say, they subdued the Saracens of Ptolemais and Judaea, and, erecting those regions into a kingdom, placed the crown upon the head of Ogier.  Guyon and Carahue then left him, to return to their respective dominions.  Ogier adopted Walter, the son of Guyon of Denmark, to be his successor in his kingdom.  He superintended his education, and saw the young prince grow up worthy of his cares.  But Ogier, in spite of all the honors of his rank, often regretted the court of Charlemagne, the Duke Namo, and Salomon of Brittany, for whom he had the respect and attachment of a son.  At last, finding Walter old enough to sustain the weight of government, Ogier caused a vessel to be prepared secretly, and, attended only by one squire, left his palace by night, and embarked to return to France.

The vessel, driven by a fair wind, cut the sea with the swiftness of a bird; but on a sudden it deviated from its course, no longer obeyed the helm, and sped fast towards a black promontory which stretched into the sea.  This was a mountain of loadstone, and, its attractive power increasing as the distance diminished, the vessel at last flew with the swiftness of an arrow towards it, and was dashed to pieces on its rocky base.  Ogier alone saved himself, and reached the shore on a fragment of the wreck.
