MEN said afterwards that the great dragon star which blazed at Ambrosius’ death and from which Uther took the royal name of Pendragon, was a baleful herald for the new reign. And indeed, at the start, everything seemed to be against Uther. It was as if the falling of Ambrosius’ star was the signal for his old enemies to rise again and crowd in from the darkened edges of the land to destroy his successor. Octa, Hengist’s son, and Eosa his kinsman, counting themselves freed by Ambrosius’ death from their promise to stay north of his borders, called together what force they could still muster for attack, and as soon as the call went out, every disaffected element rose to it. Warriors greedy for land and plunder crowded over afresh from Germany, the remnants of Pascentius’ Saxons joined with Gilloman’s fleeing Irish, and with whatever British thought themselves passed over by the new King. Within a few weeks of Ambrosius’ death Octa, with a large army, was scouring the north like a wolf, and before the new King could come up with him had destroyed cities and fortresses clear down from the Wall of Hadrian to York. At York, Ambrosius’ strong city, he found the walls in good repair, the gates shut, and men ready to defend themselves. He dragged up what siege engines he had, and settled down to wait.
