Hi
I would like to fact-check the Sarmatian connection with Arthurian legend. Quite a few websites state that Sarmatians were posted in Roman Britain, hence Sarmatian contribution to the Arthurian legend. I look forward to your feedback.

“In regarding the Sarmatians, it’s important to note their potential contributions to the lore and mythos of western civilization. Their foundation and relationship to the Amazons has already been alluded to, but their transfer to Britain has helped feed speculation on the origin of King Arthur. Lucius Artorius Castus, a Roman cavalry officer serving in the 2nd century AD has often been associated with one possible source of the true historical Arthur. Whether true or not, the Sarmatian contribution to the story is certainly one major piece of the huge Arthurian puzzle. The service of Sarmatian cavalry, from the 2nd century until the 5th century and the Roman withdrawal from Britain, along with the deeds and exploits of Artorius, may have allowed his legend to grow and foster with each successive generation of Sarmatian ‘colonists’. They also provided an invaluable contribution in post-Roman Britain, fending off Saxon invasions, which certainly helped foster the growing Arthur mythology.”
This website disputes it.
“2. While it is true that the Romans enlisted soldiers and units from border tribes like the Sarmatians, they were never posted at the other end of the empire. This would have made no sense, since the whole point of the foederati was to create a buffer between the empire and the northern and eastern barbarians. The Sarmatian soldiers were typically posted in Sarmatia.”
