I have read that there was a highly psychologically charged atmosphere between the leadership and troops in anticipation of victory following the hypothetical completion of the Schlieffen Plan in 1914 (even though they came close to Paris, now we know better that the Plan might not have worked at all because complex European alliances had created the basis for long-term war) . What do we know of Paris and France's fate as planned by Germany after the planned conquest or Paris in 1914?
More specifically, do we have any historical evidence or information of the planning by the German Army-State and their leaders following the expected conquest of Paris that never came?
There is always more to say, of course, but I focused on German war plans as they involved France (and Belgium) during the First World War in an earlier response, and you might like to review that thread while you wait for further answers to your question.
Broadly, the Germans did not have specific plans for Paris, and did not expect to occupy it (unless, we can probably assume, the French proved unwilling to agree to the terms Germany planned to dictate), but they certainly did have plans for improving their own strength, and reducing French strength, via seizure of territory and treasury – and the degree of damage that these demands would have wrought escalated as the war continued:
What did the Germans plan on doing with France and Belgium in World War 1?
