"On War" by Carl von Clausewitz is a book on military strategy written between 1816 and 1830. This unfinished work, published posthumously in 1832, explores how war functions as a continuation of politics by other means. Drawing from experiences with Napoleon and the French Revolution, Clausewitz examines the unpredictable nature of warfare, the role of moral forces in battle, and why military strategy cannot follow strict universal principles. His controversial insights continue shaping military thinking today.

Chapter I: What is War?: 1. Introduction

We propose to consider first the single elements of our subject, then each branch or part, and, last of all, the whole, in all its relations—therefore to advance from the simple to the complex. But it is necessary for us to commence with a glance at the nature of the whole, because it is particularly necessary that in the consideration of any of the parts their relation to the whole should be kept constantly in view.

2. DEFINITION.

We shall not enter into any of the abstruse definitions of War used by publicists. We shall keep to the element of the thing itself, to a duel. War is nothing but a duel on an extensive scale. If we would conceive as a unit the countless number of duels which make up a War, we shall do so best by supposing to ourselves two wrestlers. Each strives by physical force to compel the other to submit to his will: each endeavours to throw his adversary, and thus render him incapable of further resistance.
