French Revolutionary Wars: Campaigns of 1793

The French Revolutionary Wars continued from 1792, with new powers entering the First Coalition after the execution of King Louis XVI. Spain and Portugal entered the coalition in January 1793, and on 1 February France declared war on Great Britain and the Netherlands.

At the opening of the year, Dumouriez chose to ignore orders from the government in Paris to defend Belgium and instead began an invasion of the Netherlands, hoping to overthrow the stadtholder and establish a popular republic backed by France. In the event, he took Breda in Brabant and prepared to cross into Holland and capture Dordrecht. However, the armies remaining in Belgium suffered a number of defeats, with the Austrians winning battles at Aachen and Liège and raising Miranda's siege of Maastricht. Dumouriez was forced by his superiors to return to Belgium and take command in the Flanders Campaign.

After a defeat at Neerwinden, Dumouriez had to retreat from Belgium. He then made an agreement with the Austrians to hand over to them several border fortresses in return for a truce where he could march on Paris and restore the monarchy under the Constitution of 1791. However, he was unable to secure the loyalty of his troops, and he defected to the Austrian lines rather than face arrest by the Jacobins.

At the same time, the increasing power of radicals in Paris incited revolt in the provinces, with the people of Lyon and Marseille rebelling and the Vendée raising an army to attack the central government and open communications with Britain. Spanish armies crossed the Pyrenees, Sardinian armies the Alps, and Austrian armies occupied Valenciennes and forced the northern armies back on Paris. Britain ordered a naval blockade of France on 31 May.
