Anglo-Saxon Chronicle. The Chronicle then records subsequent Saxon arrivals, including that of Cerdic, the founder of Wessex, in 495. According to the Anglo-Saxon Chronicle, Cerdic and his son Cynric landed in southern Hampshire in 495, but this account is not regarded by historians as reliable due to duplication of Chronicle entries and evidence that the area was first occupied by Jutes. Although the entry mentions Cynric as Cerdic's son, a different source lists him as the son of Cerdic's son, Creoda. The Chronicle continues, stating that "Port, and his two sons Bieda and Mægla", landed at Portsmouth in 501 and killed a high-ranking British nobleman. In 508, Cerdic and Cynric slew British king Natanleod along with five thousand of his men (though the historicity of Natanleod has been disputed), and Cerdic became the first king of Wessex in 519. The Saxons attacked Cerdicesford in 519, intending to cross the River Avon and block a road which connected Old Sarum and Badbury Rings, a British stronghold. The battle appears to have ended as a draw, and the expansion of Wessex ended for about thirty years. This is likely due to losses suffered during the battle and an apparent peace agreement with the Britons. The battle of Mons Badonicus is believed to have been fought around this time. Gildas states that the Saxons were completely defeated in the battle, in which King Arthur participated according to Nennius. This defeat is not recorded in the Chronicle. The thirty-year period of peace was temporarily interrupted when, according to the Chronicle, the Saxons conquered the Isle of Wight in 530 at a battle near Carisbrooke. Cynric became the ruler of Wessex after Cerdic died in 534, and reigned for twenty-six years. The sources do agree that Ceawlin, who succeeded Cynric in about 581, is the son of Cynric; he usually is named as the father of Cuthwine. Ceawlin's reign is thought to be more reliably documented than those of his predecessors, though the Chronicle'''s dates of 560 to 592 are different from the revised chronology. Ceawlin overcame pockets of resisting Britons to the northeast, in the Chilterns, Gloucestershire and Somerset. The capture of Cirencester, Gloucester and Bath in 577, after the pause caused by the battle of Mons Badonicus, opened the way to the southwest. Ceawlin is one of the seven kings named in Bede's Ecclesiastical History of the English People as holding "imperium" over
