^ I have become an (involuntary lol) "fan" of the german small cruisers of WW1, from the Koenigsberg class and its initial SMS »Koenigsberg« to its successors, the »Emden« and the »Dresden«. ("SMS" is "Seiner Majestaet Schiff", just like "HMS").
We are currently (since years) collecting information about the german ships »Khalif« and the »Koenigsberg«, and the effort to reach German East-Africa with the Zeppelin to help the german army with their Askaris. A member of our family was a crew member of said Zeppelin, a friend was first officer on the »Khalif«. They are all dead now, unfortunately.
Its commanders and missions were well known until 1945, when the history of german military generally somehow seized to exist

Karl von Mueller, Fritz von Muecke, Graf Luckner and their men were the military heroes of the time in Germany, just like Lettow-Vorbeck.
The Zeppelin, The »Graf Goetzen« and the Africa-Zeppelin are also part of an english novel "The ghosts of Africa", fictional but with a lot of real historic details.
Most documentaries i saw are not on Youtube – which is no surprise of course, since there are no english translations i know of.
This should be english translation of one of them:
About the SMS Emden, first part
Second part is about the SMS Dresden
Also a bit of Canaris' fate:
