Watercolor cm 10x12.6, with frame 14.4x17.2. Battle of Valmy, September 20, 1792. It took place near a mill in the vicinity of the town of Valmy, a French municipality of 290 inhabitants located in the department of Marne in the Grand Est region. It marks the first victory of revolutionary France in the war against the first Austro-Prussian coalition. A motley, undisciplined army with little military experience and, moreover, significantly outnumbered (24,000 French front-line troops, of whom only 8,000 came from the old royal army, subsequently called "the Valmy ragamuffins", against approximately 35,000 Prussians and Austrians in the front line and 80,000 in total in the area) forced the troops considered the best in Europe at the time to retreat. This battle took on particular importance in the midst of the Restoration, starting with the creation of a large painting by Horace Vernet (1825) now preserved in Versailles.
