The guy you're talking about is Rudolph Hess.
His mission was to make certain that the british understood that it was in the best interest of the german state and the british empire to not have conflict in the coming war.
Hess flew over and was subsequently shot down over scotland.
He was imprisoned for teh duration of the war and afterwards was locked up in spandau until his death in the 90's.
he was never allowed to reveal what his mission was, not allowed to speak to the press and more or less tucked away in a dungeon until his demise, supposedly by suicide, although, the method of his death outweighed his ability to do it. But that's another matter.
there were plansd for 'peace in our time' between the british and the nazis under neville chamberlains great blundering plan.
The fact that Hess was never allowed to reveal his mission and took it to his grave is enough for one to raise an eyebrow about that short but likely important story in the beginnings of ww2.
Had there been an anglo-aryan empire as was the plan of hitler and for that matter the sitting king at the time edward the 7th, the whole world as we know it now would be different i would think.
edward the 7th officially abdicated his throne for the reasons of wanting to marry a commoner.
what is less revealed is that edward was a nazi sympathizer who was close friends of the hitlerian regime and it's upper circle. It could be said he himself was a nazi.
Churchill more than likely forced the abdication. Let's also not forget that the current royal family is indeed german and of the house of sax coburg and that the name windsor was created so as to not confuse the people of britain with the fact that their king and queen were germans.
and still are of teh sax coburg line by the way.
in short, what we are told as commoners is most certainly not the truth as to what is really going on in the upper echelons of the power elite who run teh countries and politics we live under.
