The First Battle of Châtillon (5 July 1793) during the War in the Vendée saw the Vendean Royalists defeat a French Republican raiding force led by François-Joseph Westermann.

The rebel Catholic and Royal Army virtually destroyed the Republican column, only Westermann and a few hundred cavalrymen escaped the disaster.

The Vendée revolt was a bitter civil war waged between those who supported the French Revolution and rural farmers who resented the new government's anti-Catholic laws and conscription decrees.

Most of the Royalist army had been pushed back during the Battle of Nantes, and their leading general Jacques Cathelineau was severely wounded.

After having approached silently, a first column of Vendéens led by Bonchamps, Lescure and La Rochejaquelein attacked the republicans on the Western plateau of Château-Gaillard.
