September 20, 2026 marks 234 years since the Battle of Valmy, in Champagne. French armies under Charles-François Dumouriez and François-Christophe Kellermann halted the coalition advance led by the Duke of Brunswick.

The invasion aimed to support the monarchy and defeat the revolution. Kellermann held the ridge by the Valmy mill; Dumouriez formed a second line. The engagement was largely an artillery duel, in wet weather.

French troops held their ground. The Prussian infantry attack did not become a decisive assault. Casualties, on usual estimates, were in the low hundreds on each side — small beside later Napoleonic battles, but not “none”.

The moral and political effect outweighed the death toll. The invaders withdrew in stages. The next day, 21 September, the National Convention abolished the monarchy and the republic was proclaimed.

Valmy became a symbol of the revolution’s survival and of armies that included volunteers. Its importance is mainly strategic and political, not a slaughter on a Napoleonic scale.

Johann Wolfgang von Goethe was with the campaign. Famous lines about a “new epoch” appear in later accounts, not as a field stenograph. We do not present them as words spoken on the spot.
