May 20 – Battle of Dun Nechtain: The Picts under King Bridei III revolt against their Northumbrian overlords. Cuthbert, bishop of Lindisfarne, advises King Ecgfrith of Northumbria (Bridei's cousin) not to invade Pictland (modern Scotland). Undeterred, Ecgfrith marches his army north to engage the enemy near Dunnichen. The Picts, possibly with Scottish and Strathclyde Briton help, defeat the Saxon guard, killing Ecgfrith, who has reigned for 15 years, routing his army and forcing the Anglo-Saxons to withdraw south of the River Forth.
King Centwine of Wessex dies after a 9-year reign and is succeeded by his distant cousin, Cædwalla, who manages to fully re-unite the sub-kingdoms of Wessex. He attacks Sussex with a large army, and kills King Æthelwealh in battle, in the South Downs (Hampshire).^[2] He is expelled by Æthelwealh's ealdormen, Berthun and Andhun, who jointly rule the South Saxons. Cædwalla invades Kent, lays it waste, and carries off an immense booty.^[3]
