AFTER THE DEATH OF UTHER PENDRAGON, the leaders of the Britons gathered in the town of Silchester and there suggested to Dubricius, the archbishop of Caerleon, that he should crown Arthur, the son of Uther, as their king. Necessity urged them on, for as soon as the Saxons heard of the death of King Uther, they invited their own countrymen over from Germany, appointed Colgrin as their leader and began to do their utmost to exterminate the Britons. They had already overrun all the country which stretches from the river Humber to the sea named Caithness.

Dubricius lamented the sad state of his country. He called the other bishops to him and bestowed the crown of the kingdom upon Arthur. Arthur was a young man only fifteen years old; but he was of outstanding courage and generosity, and his inborn goodness gave him such grace that he was loved by almost all the people. Once he had been invested with the royal insignia, he observed the normal custom of giving gifts freely to everyone. Such a great crowd of soldiers flocked to him that he came to an end of what he had to distribute. However, the man to whom openhandedness and bravery both come naturally may indeed find himself momentarily in need, but poverty will never harass him for long. In Arthur courage was closely linked with generosity, and he made up his mind to harry the Saxons, so that with their wealth he might reward the retainers who served his own household. The justness of his cause encouraged him, for he had a claim by rightful inheritance to the kingship of the whole island. He therefore called together all the young men whom I have just mentioned and marched on York.

Arthur's wars Against the Saxons

As soon as Colgrin heard this, he assembled the Saxons, Scots and Picts, and came to meet Arthur with a vast multitude. Once contact was made between the two armies, beside the river Douglas, both sides stood in grave danger for their lives. Arthur, however, was victorious. Colgrin fled, and Arthur pursued him; then Colgrin entered York and Arthur besieged him there.

When Baldulf, the brother of Colgrin, heard of the latter's flight, he came to raise the siege with six thousand troops, in the hope of freeing the beleaguered man.
