Field Marshal Mauch of Prussia What was the military ideology, did he succeed Clausewitz and what were his military writings respectively.

Do you mean old Mauch... This man was a soldier in Denmark...

Mauch always felt that Prussia had to be the one to unify Germany by force (probably his main idea).

In 1828 he published "On the Outline of Military Mapping", which must be his more major military work.

Here is a copy of Baidu's encyclopedia of Mauch's ideas.

I. The creation of a large-scale general staff system. The General Staff should be the "sole adviser" to the Commander-in-Chief (the King) in times of war, and it should formulate strategy and tactics, coordinate military and material resources, and unify the command of military operations.

II. The technological revolution must be introduced into war. Not only must the army's equipment be updated, replacing old cannon guns with newer breech-firing guns, but railroads and telegraphs must be used for war purposes. The massive construction of railroads would speed up the mobilization and deployment of the army and ensure the movement and reception of troops. Railroads and telegraphs not only overcame the previous limitations on supplies, seasons and transmission, but also made it possible to put a large number of troops and equipment into a certain battlefield in a short period of time, to form a superior force and to accomplish strategic deployment. Moltke put forward the so-called "Prussian railroad politics", the railroad, the telegraph and even the newly emerged tethered balloon as an auxiliary means of strategic action,

And a series of sciences, such as statistics, national economics, geography, surveying and so on, were used in the war.

Thirdly, the officers of the General Staff were educated and trained to adapt to the new strategy and to carry out the new war plans. The Commander-in-Chief only gave the leaders of the armies strategic objectives, while the manner of implementation of the objectives was left to the leaders of the armies themselves, who were required to give full play to their initiative. Mauch developed a set of so-called "general directives" to replace the old rigid "war orders".

Four, attack, but must "think before you act". Offense is Mauch's military principles, and "think before you act" is a guarantee of victory in the attack. "When the army begins to act, it should take into account all aspects of politics, geography and the country", requiring extremely careful, detailed, prudent and thorough planning and preparation of operational plans, deployments and actions before the war. As soon as the war began, an offensive was taken. Mauch advocated preemptive and rapid offensive warfare and opposed defensive strategies.

Here is part of Wikipedia's description of Mauch.

Mauch wrote a certain number of books on military theory. He was influenced by Carl von Clausewitz's Theory of War, and his main thesis was that military strategy must be understood as a system of choices, since the only starting point for military operations is the plannable. outcome, he considered the main task of military leadership to include extensive preparation in all possible outcomes.

I hope this helps you.
