Sub-Roman Britain (Cavalry etc)

[Agraes]

No winged spearheads in Britain by that period to my knownledge. None are displayed in Swanton's classification, and they seems to be merovingian and especially carolingian weapons.
And a 'four-sided spearhead' could stand to pretty much spearheads. You only need a midrib and then you have four faces to your spearhead.

Many of the so called Bretons in Armorica were Alans who carried quite a lot of Eastern culture with them it seems.

Sources? :roll:
I throw a good part of my free time studying early medieval Brittany and apart from a few dubious associations with the name 'Alan' (that could be a celtic name refering to animals with red fur such as deer or fox) and Gohar expedition in Armorica circa 430-440 there is no links between Bretons and Alans. We know Taifales were settled in Poitou but it's not in Brittany.

About breton cavalry, see what I said on page 13.

Bretons in the IXth century used hit-and-run tactics. That's not the heavy cavalry of lancers used by the Sarmatians or Alans. It is more common with the tactics of the Maures, also famous for their cavalry in late roman times. Magnus Maximus rallied a unit of such cavalry, and Mauri limitanei garrisonned western Armorica in the 4th century.
Even this is not obvious link for me.

Hit-and-run tactics were used by both celtic, germanic and roman cavalry for hundred of years before the stirrup came west. A 2nd (?) century roman account from Vindolanda complains about those brittunculi, fighting on horseback with javelins and never getting caught...

The Britons are unprotected by armour. There are very many cavalry. The cavalry do not use swords, nor do the wretched Britons [Brittunculi] mount in order to throw javelins.
