I am happy to answer the only question in there which, as far as I can see, is simply "could you possibly explain how Joseph Armstrong raised for much of his young life in the Morecombe Workhouse knew about the Franco-Prussian War let alone positions occupied by Prussian Artillery? I would doubt very much if you'd get 1 in 10 in the UK today that has ever even heard of the Franco-Prussian War let alone tell you when it happened."

I think it is probably because he was taught history in the workhouse. But I suspect no one will ever really know.

So, I have answered your question, despite your abuse and bluster. You have never addressed the point of what difference it made to the men who died. As usual, when faced with an uncomfortable truth, you try to change the subject.
