The most serious threat of the 1848 revolutions in Belgium was posed by Belgian émigré groups. Shortly after the revolution in France, Belgian migrant workers living in Paris were encouraged to return to Belgium to overthrow the monarchy and establish a republic. Around 6,000 armed émigrés of the Belgian Legion attempted to cross the Belgian frontier. The first group, travelling by train, was stopped and quickly disarmed at Quiévrain on 26 March 1848. The second group crossed the border on 29 March and headed for Brussels. They were confronted by Belgian troops at the hamlet of Risquons-Tout and, during fighting, seven émigrés were killed and most of the rest were captured. The defeat at Risquons-Tout effectively ended the revolutionary threat to Belgium. The situation stabilized that summer after a good harvest, and fresh elections returned a strong Liberal majority.
