The Battle of Fleurus, fought on June 26, 1794 was one of the most decisive battles in the Low Countries during the French Revolutionary Wars.

Both sides had forces numbering in the vicinity of 80,000 men and the French, under Jourdan were able to more effectively concentrate their forces in order to achieve victory against the Austrian army under Saxe-Cobourg.

This victory precipitated a full Allied withdrawal from Belgium and allowed French forces to push north into Holland.

The Battle largely invalidated the argument that continuation of the French Revolutionary Reign of Terror was necessary because of the military threat to France's very existence. Consequently, Robespierre's dictatorship was overthrown a month later.
