Dear John,
From some of my notes on WW I.
Archduke Francis Ferdinand was assassinated by Gavrilo Princip a young man that had been of the Orthodox faith but became an ardent follower of Mikhail Bakunin whose anarchism was used as a basis for the communism to come later to Russia. I will try to dig up the info I know I have someplace as to the Jewish ancestry of Pricip. (I believe his mother)
Colonel Dragutin Dimitrijevic or the Serbian Army military intelligence known as "Apis" had an organization known as "Black Hand" (which was run by Zionist Jewish  Masons at the helm) planned the assassinations of both Frances Ferdinand and Duchess Sophie Hohenberg in Sarajevo.
One Major Voja Tankosic a trusted lieutenant of Apis manipulated the Princip group.
All indications point to the Jewish influence behind the whole incident. In order to take over any nation led by nobility you first have to eliminate the nobility.
Captain Alexander Werchovski a Russian military attche' under the Czar who apparently was the only one who actually knew all the players connections went on to hold a high command in the Soviet Red Army.
I will continue to check on Princip and get back to you ASAP. I read something about him not very long ago it's just a case of finding it and putting it in my library card file.
Sir Peter
