The Battle of Valmy was a stunning French victory over a Prussian-led coalition army on 20 September 1792, during the French Revolutionary Wars (1792-1802). Although the battle was little more than a skirmish, it halted the coalition's invasion, allowed for the establishment of the First French Republic, and ensured the continuation of the French Revolution (1789-99).
