I read the bit about the lady's "brutal streak." Revisionist BS, say I.
I don't doubt that she did the things attributed to her in the article, but disagree as to the adjective "brutal." But, then, it did seem somewhat proto-Cromwellian. I would be more inclined to call it (at least in her case)"righteous vengenance" or "militarily efficient," or some such. Viewed from a perspective more in tune with her time, she would have been an incompetent leader to do less than she did. Although she lived and died in what is today widely know as England, I suspect that she might take umbrage at being called British. She was a Celt, though I recognize that the word "Celt," in whatever form she knew it, might not have carried the same meaning commonly ascribed to it today.
