The Swiss guards at the Tuileries attempted to make some resistance, but the mob drove them from their posts and killed many of them. The reign of terror spread. Nobles or citizens who had opposed the Jacobins were hunted out and murdered. When the Assembly adjourned the deputies found armed bands at the doors, waiting to kill all those who were known to have supported the constitution.
Meantime the royal family had found the Assembly a poor refuge. A deputy had moved that the King be dethroned and a convention summoned to determine the future government of the country. The measure was instantly carried. Louis XVI. and his family were handed over to officers who took them to the Temple, which then became their prison.
The Jacobins had won the day by force and violence. They formed a government called the “Commune of August 10th,” filled it with their own men, drove all respectable soldiers out of the National Guard and placed Jacobin pikemen in their places. All nobles and friends of the King who were found in Paris were thrown into the prisons, which were soon crammed. The Reign of Terror had begun in fact. Only a short time later the prisoners were being tried and sent to the guillotine.
Lafayette heard of the events of August tenth and begged his troops to remain true to the King and the constitution. Then the Commune of Paris sent commissioners to the armies to announce the change of government and to demand allegiance to the Commune. Lafayette met the commissioners at Sedan, heard their statements, and declaring them the agents of a faction that had unlawfully seized on power, ordered them imprisoned.
News of Lafayette’s arrest of the commissioners added to the turmoil in Paris. Some Jacobins wanted to have him declared a traitor at once; others, however, feared that his influence with the army might be too great for them to take such a step safely. But troops in the other parts of France had come over to the Commune, and so, on the nineteenth of August the Jacobin leaders felt their power strong enough to compel the Assembly to declare Lafayette a traitor.
Lafayette now had to face a decision. France had declared for the Commune of Paris and overthrown King and constitution. He had three choices. He might accept the rule of the Jacobins and become one of their generals; he might continue to oppose them and probably be arrested by his own soldiers and sent to the guillotine; he might leave the country, seek refuge in some neutral land, and hope that some day he could again be of service to liberty in France. To accept the first course was impossible for him, because he had no confidence in Jacobin rule. To take the second would be useless. Therefore the third course was the one he decided on.
He turned his troops over to other officers, and with a few friends, who, like himself, had been declared traitors because they had supported the constitution, rode away from Sedan and crossed the border into Belgium at the little town of Bouillon. He was now an exile from his own country. The cause of liberty that he had fought so hard for had now become the cause of lawlessness. His dream of France, safe and prosperous under a constitution like that of the young republic across the sea, had come to an end, at least for the time being. He could do nothing but wash his hands of the Reign of Terror that followed on the footsteps of the Revolution he had helped to start.
