Friends.
Extraordinary contributions.
Thank you for his comment Johan, excellent.
A small contradiction exists on the sinking or not, of the English U-Boat by Friedensburg and Walter.
In Internet exists a text, in German, refers to the sinking of the U-Boat (HMS E-11) by Friedensburg, and says the following thing:
Friedensburg, Walter
Im 1. Weltkrieg Frontflieger und Kommandeur verschiedener Fliegerabt.; vernichtet 1915 mit Seeflugzeug 53 das erste feindliche U-Boot (engl. U-Boot E-11); Kaiserl. Kapitänleutnant a.D.; 1920 Imex-Kommanditgesellschaft Friedensburg & Co.
Was it really victorious Friedensburg on an English U-Boat?
Which the correct date is?
Which the correct submarine is?
What airplane type flew that day?
Some photo of Friedensburg during the Great War?
Some other fact about his life?
Pilotenschein- Nummer 407 - 20.05.1913
In idflieg.de:
Leutnant zur See Walter Friedensburg *06.01.1889 Breslau. (Berlín? Breslau?)
