King Nanteleod of Escavalon wins a small battle against the king of Brycheiniog and gains his vassalage. Resistance is only perfunctory, as if the king of Byrcheiniog had really wanted to aid Nanteleod. Then King Nanteleod, with the newly allied hill men, marches west and attacks the Irish in their own kingdom of Estregales. The King of Estregales is unprepared, but with his small household forces and local muster he fights a battle anyway, and is soundly defeated.
Now Estregales has sworn vassalage to Nanteleod of Escavalon.
