Napoleon is widely admired as a military strategist who embraced the violence of modern war and understood the potential of mass armies. Yet he wrote little about the practice of strategy beyond a few rather bland maxims, claiming to rely on offence and opportunism on the battlefield. But these offensive tactics had a strategic purpose. He sought to crush his opponents in decisive battles, not just to destroy enemy armies but to impose his will in the peace talks that followed. As First Consul and later as Emperor he channelled the resources of the state to the cause of military success and imperial expansion. His goal was political as much as it was military, mobilising all the resources of the Empire in its pursuit. Napoleon conscripted mass armies in the lands he conquered, imposed French-style administrative systems, and imposed taxes and customs duties. He was focused on Europe, where the other powers developed their own strategies to counter him, repeatedly forging alliances to defend their sovereignty and to thwart his imperial ambitions. Each country had its own war aims. Russia looked to expand into the Balkans, Prussia to conquer Poland, and Britain to consolidate its colonial presence overseas.
