<P> When it became evident, in mid-July 1794, that Robespierre and Saint - Just were planning to strike against their political opponents Joseph Fouché, Jean - Lambert Tallien, and Marc - Guillaume Alexis Vadier (the latter two of whom were members of the Committee of General Security), the fragile truce within the government was dissolved . Saint - Just and his fellow Committee of Public Safety member Barère attempted to keep the peace between the Committees of Public Safety and General Security; however, on 26 July, Robespierre delivered a speech to the National Convention in which he emphasized the need to "purify" the Committees and "crush all factions ." In a speech to the Jacobin Club that night, he attacked Collot d'Herbois and Billaud - Varenne, who had refused to allow the printing and distribution of his speech to the Convention . </P> <P> On the following day, 27 July 1794 (or 9 Thermidor according to the Revolutionary calendar), Saint - Just began to deliver a speech to the Convention in which he had planned to denounce Collot d'Herbois, Billaud - Varenne, and other members of the Committee of Public Safety . However, he was almost immediately interrupted by Tallien and by Billaud - Varenne, who accused Saint - Just of intending to "murder the Convention ." Barère, Vadier, and Stanislas Fréron joined the accusations against Saint - Just and Robespierre . The arrest of Robespierre, his brother Augustin, and Saint - Just was ordered, along with that of their supporters, Philippe Le Bas and Georges Couthon . </P> <P> A period of intense civil unrest ensued, during which the members of the Committees of Public Safety and General Security were forced to seek refuge in the Convention . The Robespierre brothers, Saint - Just, Le Bas, and Couthon ensconced themselves in the Hôtel de Ville, attempting to incite an insurrection . Ultimately, faced with defeat and arrest, Le Bas committed suicide . Saint - Just, Couthon, and Maximilien and Augustin Robespierre were arrested and guillotined on 28 July . </P> <P> The ensuing period of upheaval, dubbed the Thermidorian Reaction, saw the repeal of many of the Terror's most unpopular laws and the reduction in power of the Committees of General Security and Public Safety . The Committees ceased to exist under the Constitution of the Year III (1795), which marked the beginning of the Directory . </P>
