The battle of Wagram in 1809

Horace Vernet's The Battle of Wagram of 1836 depicts Napoleon's July 1809 victory over Archduke Charles's Austrian army on the plain north of Vienna — one of the largest battles of the Napoleonic Wars, with over three hundred thousand men engaged. The battle demonstrated Napoleon's operational mastery but at heavy cost, and the subsequent Peace of Schönbrunn temporarily removed Austria from the conflict. Vernet was the supreme practitioner of Napoleonic battle painting, and his Wagram canvas reproduces the chaos of mass action through the kind of panoramic organization that military history painting demanded.

The panoramic battlefield composition conveys the enormous scale of Napoleonic warfare with precise detail in uniforms, artillery, and formations. Vernet's characteristic clarity makes the complex tactical situation readable.
