Carl von Clausewitz is still considered one of the most important writers on military strategy. In Prussian Military Thought 1815-1830: Beyond Clausewitz , Jacek Jędrysiak offers a new perspective on the context of his legacy, with a detailed analysis of Prussian military thought after the Napoleonic wars and an examination of the development of certain institutions, such as the General Staff, leading to a more nuanced understanding of Clausewitz’s work. The dominance of the famous figures of Clausewitz and Helmuth von Moltke the Elder has obscured much about the Prussian army in the 19th century. In this study, Jacek Jędrysiak reveals the forgotten face of the Prussian army.
