Anglo-Saxon Chronicle. 800. This year was the moon eclipsed, at eight in the evening, on the seventeenth day before the calends of February; and soon after died King Bertric and Alderman Worr. Egbert (age 27) succeeded to the West-Saxon kingdom; and the same day Ethelmund, alderman of the Wiccians, rode over the Thames at Kempsford; where he was met by Alderman Woxtan, with the men of Wiltshire, and a terrible conflict ensued, in which both the commanders were slain, but the men of Wiltshire obtained the victory.

Anglo-Saxon Chronicle. 823. This year a battle was fought between the Welsh in Cornwall and the people of Devonshire, at Camelford, Cornwall; and in the course of the same year Egbert, king of the West-Saxons (age 50), and Bernwulf, King of Mercia, fought a battle at Wilton, in which Egbert gained the victory, but there was great slaughter on both sides. Then sent he his son [his son] Ethelwulf into Kent, with a large detachment from the main body of the army, accompanied by his bishop, Elstan, and his alderman, Wulfherd; who drove Baldred, the king, northward over the Thames. Whereupon the men of Kent immediately submitted to him; as did also the inhabitants of Surrey, and Sussex, and Essex; who had been unlawfully kept from their allegiance by his relatives. The same year also, the king of the East-Angles, and his subjects besought King Egbert to give them peace and protection against the terror of the Mercians; whose king, Bernwulf, they slew in the course of the same year.

In Sep 825 Beornwulf King Mercia defeated Ecgberht, King of Wessex (age 52), at the Battle of Ellendun replacing Mercian with Wessex dominance over the Saxon Heptarchy. Sir Frank Stenton described it as 'one of the most decisive battles of English history'. The location of the battle is not known although a number of locations have been suggested: Wroughton, Wiltshire, Lydiard Park Swindon, Wiltshire and Wilton, Wiltshire [Map].

Anglo-Saxon Chronicle. 836. In this year, King Ecgbryht (age 63) fought against thirty-five shiploads [of Danes] at Charmouth, and there a great slaughter took place, and the Danes held the battlefield; and Hereferth and Wigthegn, two bishops, passed away, and Dudda and Osmund, two aldermen, passed away.

Anglo-Saxon Chronicle. 838. In this year, a great fleet came to West Wales, and they united together and fought against Ecgbryht (age 65), king of the West Saxons. When he heard of this, he marched with his army and fought against them at Hengestdun, and there he put to flight both the Welsh and the Danes.
