“The King gathered a mighty army together and went his way into the province of Cornwall and set fire to the cities and castles therein. When they met face to face in battle, Gorlois was amongst the first that were slain, and all his companies were scattered. The King was sore grieved at the death of Gorlois, yet could he not but be glad that Igerne was released from the bond of matrimony. Thereafter were they linked together in no little mutual love, and two children were born unto them, a son and a daughter, whereof the son was named Arthur and the daughter Anna.”
