Sub-Roman Britain (Cavalry etc)

[Medicus matt]

Oh well, I figured it would be a good topic. I mean, it didn't just appear out of nowhere, and most things about the Welsh military started in this era so I'm wondering if the Welsh longbow did as well. Could it have been inspired by some kind of Roman bow?

I doubt very much that 'most things about the Welsh military' started in the Roman period.
Longbows are OT as long as no-one comes forward with a direct link between Roman bows and Welsh longbows.

It's heresy to even mention it this close to the Welsh border but I think that the earliest examples of single D-section/sub round section 'longbows' are those found in the late iron age/migration period Danish bogs and suspect that they were introduced into the country by northern Germanic forces.

It's an interesting topic in it's own right but not one for a Roman military forum I would have thought.
