I wouldn't agree on "experiental attack" : you had rezzous on Betica since the late VIIth century after all, and the 710 raid might have not been much more that another precedent one (as the later raids in Gaul) while it's possible that the loot and the results were encouraging enough to have a mostly Berber expedition in Spain (altough 7000 or 12000 is certainly a bit too much : logistically and knowing a bit how armies evolved in Maghrib, you could easily reduce it by half or at least two-thirds).
I meant it was just a test the watters kind of thing.
A raid big enough to hurt but small enough to pass as a raid just to see how Roderick's control was.
7000-12000 I personaly bet on a small figure. I read that Tariq reached the peninsula with 7000 but fought the battle with 12000 so I guess some visigoths fought on his side.
Which doesn't meant that Achila did that or even took the decision : the southern Vittizists were essentially their own men, and maybe their own pretenders (as Oppa), so while Achila certainly didn't demonstred any real intend to deal with Arabo-Berbers (it seems he was let to himself as was Ardo, in the North-Eastern corner until 718), I don't think it's impossible to see Achila joining forces with Roderic : for exemple if Oppa or another southern Gothic nobles tried to use Arabo-Berbers for his own ends.
Agila went to Damascus in 712 to receive the blessing of the Umayyads as the King of the Visigoths so I thought he was the one of the group that had the idea to call them to aid him. I doubt the Bishop of Toledo would go to Morocco if he didn't had the blessing of Agila or from someone powerful enough on his party.
We know virtually nothing about the battle : we can assume from usual Arabo-Berber tactics that they did used light cavalry, but not only the Gothic army must have been composed more from just cavalry if we follow the traditional ordinances on the matter, but it's not really impossible (and even credible) that Arab or North African heavy cavalry may have been decisive.
I'm not saying it was the case, tough, just merely it could as well have been giving our knowledge of the battle.
The Gothic army just cavalry?
I think you misunderstood me.
I meant that Roderick's cavalry was killed by the Berber light cavalry, his horse was found killed by dozens of arrows, and that with the gothic cavalry dead the Arabs flanked the infantry. This could explain the knowledge we have that the Gothic flanks were unprotected.
Not necessarily : as you said, in the situation he does win without Achila, he would have certainly fewer resources avaible and would have to choice between attacking 1) Achila, 2) Arabo-Berbers (without even mentioning Vascons, of course). Giving the long established tradition in Gothic Spain to resort to sub-kingdoms during crises, I'd suspect that Achila would have been let (I'm not saying acknowledged) as a sub-king or anti-king in the eastern part (basically what Paulus attempted some decades then)
I think Roderick would be put on the defensive.
Agila would try to gain for the situation that comes after the battle with Roderick's forces almost being defeated. His men are rested and his army is intact while Roderick just lost many men.
Actually, if we can follow the treaties passed between Arabo-Berbers and Goths, you have a lot of names associated with Vittizean support popping around Betica : it's more probable that Betica itself wasn't or only partially, under Roderic's control (and maybe why he prefered to deal with Vascons than the Arabo-Berber raid of 710)
From what I read the division was confusing. Roderick got Lusitania and Carthaginiensis, but if that is true then Baetica would be of Agila and then it would be cut off from Agila's support in Tarraconensis.
I just went with a source that claims that "Agila and his partisans controlled the north and east of Spain; Roderick and his, the south and west".
No, or at least, not like that. The anti-dynastic nature of the Visigothic kingdom was something expected for (or, as we could put it : "it's not a bug, it's a feature"). Basically the gothic magnates of Spain feared the establishment of a dynasty that could impair their power, and managed to provoke a cycle of anti-dynastic succession whom a good part managed to avoid civil war. (Roger Collins wrote a very interesting article on this matter : the ongoing trend since decades wasn't centralisation but a lot of caution to prevent dynastical succession)
Would Achila attempt to change something that institutional, he would likely face an important revolt eventually.
Not that, eventually, it woudn't be a challenge that Gothic kings or curia wouldn't have to face : but if they attempt to do so during the VIIIth century, when they would be at their weakest, they would likely fail.
That said, failure is an option there : we can't rule out a Gothic magnate (most probably from the western corner, due to economical changes that would benefit western courts) pulling a Peppinid partially because the anti-dynastic kings before didn't manage to and made Gothia implode.[/QUOTE]
Can you link me the article? I would like to read it sounds interesting.
Also I don't mean that Agila would do anything, he sounds too weak to do anything, just that the birth of a dynasty would aid in uniting the Gothic Kingdom in the long turn.
