Earthen embankments were still in use, as cravats I think, where you pile up earth on both sides of the wall, which strengthen the walls, which was well used for stone walls. Besides which, using earth embankments were still common simply because it makes it harder to siege a fortification if you have to scale an embankment, or to traverse a series of Dikes supported by Embankments. You seem to think that simply saying that Barca uses earth, or wood, as apart of their fortifications is insulting, which it isn't.
I don't think we are going to agree on this even though we both have good descriptions on what we see in the matter. You see one thing, I see another. We should agree to disagree.
