At the outbreak of the French Revolution, Victor Amadeus III allowed his two sons-in-law, the Counts of Artois, Provence and the Princesses Marie Adélaïde and Victoire to stay in his kingdom under his protection. After four years of fighting, the French under Bonaparte had finally beaten the Piedmontese army in the Battle of Montenotte (12 April 1796), the Battle of Millesimo (13–14 April 1796) and the Battle of Mondovi (21 April 1796). On April 26 the French proclaimed the Republic of Alba on the occupied territories. Two days later, with the Armistice of Cherasco, the Republic was ceded back to Victor Amadeus. He was forced to sign the Treaty of Paris on May 15 abandoning the First Coalition against the French Republic. The terms of the treaty required him to cede the fortresses of Cuneo, Ceva, Alessandria and Tortona to France, and allow free passage of the latter's armies towards Italy. He was also compelled to cede Nice and Savoy.
