When Lafayette heard of the insurrection in Paris he tried to rally his troops in defence of the constitution, but they refused to follow him. He was driven to cross the frontier and surrender himself to the Austrians. Dumouriez was named his successor. But the new government was still beset with danger. It had no root in law and little hold on public opinion. It could not lean on the Assembly, a mere shrunken remnant, whose days were numbered. It remained dependent on the power which had set it up, the revolutionary Commune of Paris. The Commune could therefore extort what concessions it pleased. It got the custody of the king and his family who were imprisoned in the Temple. Having obtained an indefinite power of arrest, it soon filled the prisons of Paris. As the elections to the Convention were close at hand, the Commune resolved to strike the public with terror by the slaughter of its prisoners. It found its opportunity in the progress of invasion. On the 19th Brunswick crossed the frontier. On the 22nd Longwy surrendered. Verdun was invested and seemed likely to fall. On the 1st of September the Commune decreed that on the following day the tocsin should be rung, all able-bodied citizens convened in the Champs de Mars, and 60,000 volunteers enrolled for the defence of the country. While this assembly was in progress gangs of assassins were sent to the prisons and began a butchery which lasted four days and consumed 1400 victims. The Commune addressed a circular letter to the other cities of France inviting them to follow the example. A number of state prisoners awaiting trial at Orleans were ordered to Paris and on the way were murdered at Versailles. The Assembly offered a feeble resistance to these crimes. Danton can hardly be acquitted of connivance at them. Roland hinted disapproval, but did not venture more. He with many other Girondins had been marked for slaughter in the original project. The National Convention. Abolition of the monarchy.
