This book investigates whether Carl von Clausewitz, traditionally viewed as a theorist of major interstate conflict, was fundamentally shaped by his analysis of small-scale partisan warfare. Sibylle Scheipers, a scholar of military history and political theory, examines Clausewitz's intellectual evolution by situating his writings within the broader context of German Idealism, Romanticism, and Humanism. By tracing the integration of his early thoughts on irregular warfare into his later work, the author argues that Clausewitz's strategic framework was deeply informed by the necessity of defending Prussia against Napoleonic expansionism.

Scholars and military historians recognize this work as a significant re-evaluation of Clausewitzian theory that corrects the narrow focus on conventional interstate war. Readers frequently note the academic density of the prose, which requires a foundational understanding of 19th-century European political philosophy to fully appreciate.
