Yes it's the same, I don't know why Cornwell started calling them the Saxon Stories instead of Tales. One interesting fact is that Cornwell is actually descended from the rulers of Bebbenburg (now Bamburgh) which still exists, some of whom were named Uhtred, though it's by no means intended as a biography. It's certainly every bit as imposing a fortress as Cornwell describes, though of course back then it was only an earth and wood fortress, not a stone castle.
