All important parts are tranlated and clearly to be read.
... well ... such things happen, if mayor sources keep ignored
... esp. if the few parts 'told' as translated (
... how far also 'interpreted' we don't know) by the one to few sources relate to outdated data for the topic discussed (
in the thread cited by me as well as here).
However ... IMHO the rather decisive statement of the man in charge of logistics in 1914 ...
... translated and rather diffucult to be ... 'reinterpreted'.
... but ofc you'r free to consider or not consider whatever sources you like.
Also, in Terence Zuber's "Inventing the Schlieffen Plan: German War Planning 1891-1914"
He states:
...in regards to the "Aufmarsch II in 1900/1"
"Aufmarsch II in 1900/1 was a true
Ostaufmarsch, a massive deployment to the east the likes of which had not been seen since 1880: Schlieffen proposed to send 44 divisions to the east and only 24 to the west [...] five corps and 10 reserve divisions (20 divisions in total) to be assembled around Thorn, and nine corps and five reserve divisions (24 divisions in total) in eastern East Prussia."
"Given the high proportion of active army corps it contained, Schlieffen intended that the second, East Prussian group, conduct the main effort.
The limited capacity of the Prussian rail net east of the Vistula meant that assembling 24 divisions in eastern East Prussia would have been a very time-consuming process, which would have sacrificed any hope of achieving surprise. "
...in regards to the "1905 Kriegsspiel"
"This was by far the most ambitious exercise of Schlieffen’s career, perhaps the greatest war game in modern military history."
"His concept for the operation was to conduct a strong initial
Aufmarsch in East Prussia with 16 divisions (five corps and six reserve divisions). When the Russians had committed themselves to attacking, he would reinforce the eastern force with an additional 22 divisions (eight corps and six reserve divisions).
This total of 38 divisions was all that the East Prussian rail net could support. "
...in regards to the "Die Befestigung und Verteidigung der deutsch-russischen Grenze"
"The German rail net in the east was suitable for the defense.
There were four rail bridges over the Vistula into East Prussia. Two of these rail lines led to north-eastern East Prussia, while a major German rail line ran parallel with the border from Posen to Breslau. This would facilitate a defensive German deployment and troop movements.
On the other hand, rail communications from Poland into Germany were practically non-existent. One rail line ran parallel to the Vistula, but it was blocked by Fortress Posen. For a 400-kilometer stretch from Posen south to Silesia only one rail line crossed the border, and this was in the extreme south."
And, if you'd like to dispute his claims, there are the sources (in German) he uses. You, being German, have the ability to read, translate & interpret these sources. It would mean an end to the "Grosser Ostaufmarsch" logistics debate.

In addition.
In Terence Zuber's "German War Planning, 1891-1914 Sources and Interpretations", in-which there are precise English translations of extremely reliable German figures/historians, it states:
(actual original translated text)*In reference to Groener, the person you use as "definitive proof" 's "
"[Handwritten] Comments on the Denkschrift from the Military History Section concerning the "Development of the Operational Concept in a Two-Front War of 1871-1914."
[From the Denkschrift, Handwritten]: Re: Denkschrift by Field Marshal von Moltke immediately after 1871 pointed out the possibility of a simultaneous war with France and Russia. It said there was a need to consider
in good time to provide for the means for the defensive.
[Groener's comment. Typed] In my opinion, given such a combination, there were only two remedies:
a) military training for the entire male population
b) massive expansion of the rail net.
[...]
[From the Denkschrift] Up to his retirement (in 1888), Moltke advocated the offensive against Russia.
[Groener] The plan for an offensive against Russia suffered from one great deficiency: the preparations for the expansion of the lines of communication were just being formulated.
There was a lack of railway troops. The field railway system with locomotives was just being formed, but was still a very shaky supply system... Fast and decisive operations were hardly to be expected, given the transportation networks of the time.
I am currently awaiting further English translations of key documents. If I get them, I will post small segments here to hopefully invoke further discussion.
