Battle of Badon
（重定向自Badon）
The Battle of Badon (Latin: Bellum in monte Badonis or Mons Badonicus, Welsh:Cad Mynydd Baddon, all literally meaning "Battle of Mount Badon" or "Battle of Badon Hill") was a battle thought to have occurred between Britons and an Anglo-Saxons in the late 5th or early 6th century. It was credited as a major victory for the Britons, stopping the encroachment of the Anglo-Saxon kingdoms for a period. It is chiefly known today for the supposed involvement of King Arthur, a tradition that first clearly appeared in the 9th-century Historia Brittonum. Because of the limited number of sources, there is no certainty about the date, location, or details of the fighting.
