Where is the hard evidence of any trip to Russia by the last Tsarina's brother, the Grand Duke of Hesse-Darmstadt? The answer is there in none whatsoever. The so-called "evidence" comes from the proven imposter Anderson who was committed to asylums on more than one occasion.
There is hard evidence that the trip or something smilar was at least contemplated at the highest levels. The evidence has nothing whatsoever to do with Anna Anderson, as even Annie now realises, and even in 1915 Berlin found it necessary amidst a storm of rumour to deny that the visit had taken place.
Even IF the trip DID happen which is unlikely, there was still the book "In the Face of the Revolution" (B. Himmelstjerna, "Im Angesicht der Revolution", 1922, the publisher is Steeler) that openly accused Ernie of making the trip and claiming to have facts to back it up. This book existed THREE years before AA mentioned it. It's highly probable that AA and/or one of her supporters saw the story in the book and used it. This does NOT mean AA knew anything special or that she was in Russia. The revelation of the existence of this book completely destroys the alleged 'bomb' 'how did she know' part of the AA charade.
To put it plainly: AA/FS and/or her supporters learned of this alleged trip from the 1922 book and tried to use it to 'prove' she was in Russia in 1916.
(this does not mean I 'now realize' the trip happend, I'm only giving evidence that the rumor of the story existed prior to AA telling about it, so this proves AA wasn't privy to any special secret or' inside information' 'only AN would know' as supporters like to claim.)
