There are potentially n different translations out there, and n-1 of them are historically inaccurate if not actually wrong from a linguistic point of view. However, and I was hoping not to have to go into this, it's actually a longer article than most in the Wikipedia in itself, the word in AS is unraede, "without counsel" meaning that (to paraphrase Monty Python) in the ultimate balance, when all was said and done, at the final whistle, at a time of major national crisis he had absolutely no answers whatsoever for the problems which confronted him, and, moreover, as those who gave hime the nickname would have been fully aware, nobody on which he could rely to turn to for those answers. It is an Anglo-Saxon form of joke, an ironic pun, and is a) exceptionally cruel and b) searingly accurate. It doesn't just mean he was unprepared, it means he didn't have a fecking clue.
