64. Oswald son of Ethelfrid, reigned nine years; the same is Oswald
Llauiguin;(1) he slew Catgublaun (Cadwalla),(2) king of Guenedot,(3) in
the battle of Catscaul,(4) with much loss to his own army. Oswy, son of
Ethelfrid, reigned twenty-eight years and six months. During his reign,
there was a dreadful mortality among his subjects, when Catgualart
(Cadwallader) was king among the Britons, succeeding his father, and he
himself died amongst the rest.(5) He slew Penda in the field of Gai, and
now took place the slaughter of Gai Campi, and the kings of the Britons,
who went out with Penda on the expedition as far as the city of Judeu,
were slain.

(1) Llauiguin, means the "fair," or the "bounteous hand."

(2) This name has been variously written; Bede spells it
Caedualla (Cadwalla); Nennius, Catgublaun; the Saxon
Chronicle, Ceadwalla; and the Welsh writers, Cadwallon and
Kalwallawn: and though the identity of the person may be
clearly proved, it is necessary to observe these particulars
to distinguish him from Cadwaladr, and from another
Caedualla or Caedwalla, a king of the West Saxons; all of
whom, as they lived within a short time of each other, have
been frequently confounded together.--Rees's Welsh Saints.

(3) Gwynedd, North Wales.

(4) Bede says at Denis's brook.

(5) The British chronicles assert that Cadwallader died at
Rome, whilst Nennius would lead us to conclude that he
perished in the pestilence at home.
