Battle of Beaumont during the Flanders Campaign of the War of the First Coalition.

The Battle of Beaumont-en-Cambrésis 26 April 1794 was an action forming part of a multi-pronged attempt to relieve the besieged fortress of Landrecies, during the Flanders Campaign of the French Revolutionary War. The British and Austrians under the Duke of York defeated a French advance northwards from Cambrai commanded by René Chapuis.

The Low Countries theatre of the War of the First Coalition, also known as the Flanders campaign, was a series of campaigns in the Low Countries conducted from 20 April 1792 to 7 June 1795 during the first years of the War of the First Coalition. As the French Revolution radicalised, the revolutionary National Convention and its predecessors broke the Catholic Church's power (1790), abolished the monarchy (1792) and even executed the deposed king Louis XVI of France (1793), vying to spread the Revolution beyond the new French Republic's borders, by violent means if necessary. The First Coalition, an alliance of reactionary states representing the Ancien Régime in Central and Western Europe – Habsburg Austria, Prussia, Great Britain, the Dutch Republic, Hanover and Hesse-Kassel – mobilised military forces along all the French frontiers, threatening to invade Revolutionary France and violently restore the monarchy. The subsequent combat operations along the French borders with the Low Countries and Germany became the primary theatre of the War of the First Coalition until March 1796, when Napoleon took over French command on the Italian front.

The War of the First Coalition was a set of wars that several European powers fought between 1792 and 1797, against France. They were only loosely allied and fought without much apparent coordination or agreement; each power had its eye on a different part of France it wanted to appropriate after a French defeat, which never occurred.
