This was a speech I read that was originally written and given by Rudolf Hess' son Wolf Hess. It mostly regards the events surrounding Hess Sr.'s Peace Mission that landed him jailed in the hands of the Allied Imprisonment until they murdered him at the age of 93. The Speech was originally published by the Institute for Historical Review. Link: https://www.ihr.org/

I don't know much about Bowden. Wikipedia describes him as an English far-right writer and politician. He seems to have a pretty large body of written work.
