Battle of Mount Badon

Type of action: Ground battle in defense of Britain

Date: between 495 and 516

Location: probably Bath, England

Combatants: Celts vs. Saxons

Principal commanders:Celtic, Arthur (c. 475-c. 537); Saxon, Aelle (fl. 500)

Result: Significant defeat of the Saxons

Although the historical evidence for the Battle of Mount Badon is thin, there is little reason to doubt it. It is referred to by Gildas in his De Excidio Britanniæ (The Ruin of Britain), written sometime in the late 540’s. He dates it to the year of his birth, forty-three years earlier. This would place the battle around 503. However the Annales Cambriæ (Welsh Annals) date it at 516, and a later date has much in its favor. It was the last of twelve battles by Arthur, the Celtic king. These ran the length and breadth of Britain against Saxons and other aggressors, including the Picts and Irish. The likeliest location for Badon is in southwest Britain, probably Bath, although many other sites have been suggested as far afield as Wales, Scotland, and Northern Ireland. The battle lasted for three days. A possible scenario is that Arthur drew his cavalry onto a hilltop, probably Soulsbury Hill outside Bath, and was there besieged by Saxon infantry, under Aelle of the southern Saxons, who was the Saxon bretwalda. Arthur led a charge against the Saxons where he killed almost one thousand.

Significance

The battle was so decisive that it halted the Saxon advance and ushered in a period of relative calm, lasting for about forty years, an Arthurian Golden Age. It probably destroyed the southern Saxons, as they disappeared from the Chronicles for more than 150 years.
