When, on July 27, 1793, Robespierre entered the Committee of Public Safety, the fortunes of the Republic were near their nadir, but almost immediately, after Carnot took the War Department on August 14, they began to mend. On October 8, 1793, Lyons surrendered; on December 19, 1793, the English evacuated Toulon; and, on December 23, the insurrection in La Vendée received its death blow at Savenai. There had also been success on the frontiers. Carnot put Hoche in command in the Vosges. On December 23, 1793, Hoche defeated Wurmser at Freschweiller, when the Austrians, abandoning the lines of Wissembourg, fell back across the Rhine. Thus by the end of 1793, save for the great border fortresses of Valenciennes and Condé to the north, which commanded the road from Brussels to Paris, the soil of France had been cleared of the enemy, and something resembling domestic tranquillity had been restored at home. Simultaneously, as the pressure lessened, rifts began to appear in the knot of men who held the Dictatorship in the Republic. Robespierre, Couthon, and Saint-Just coalesced, and gained control of the police, while Billaud-Varennes, Collot-d'Herbois, and, secretly and as far as he dared, Barère, formed an opposition. Not that the latter were more moderate or merciful than Robespierre, but because, in the nature of things, there could be but one Dictator, and it became a question of the survival of the fittest. Carnot took little or no part in active politics. He devoted himself to the war, but he disapproved of the Terror and came to a breach with Saint-Just. Robespierre's power culminated on June 10, 1794, with the passage of the Law of 22 Prairial, which put the life of every Frenchman in his hand, and after which, save for some dozen or two of his most intimate and devoted adherents like Saint-Just, Couthon, Le Bas, Fouquier, Fleuriot the Mayor of Paris, and Henriot, the commander of the national guard, no one felt his head safe on his shoulders. It needed but security on the northern frontier to cause the social centre of gravity to shift and Robespierre to fall, and security came with the campaign of Fleurus. Jourdan and Pichegru were in command on the Belgian border, and on June 26, 1794, just sixteen days after the passage of the Law of Prairial, Jourdan won the battle of Fleurus. This battle, though not decisive in itself, led to decisive results. It uncovered Valenciennes and Condé, which were invested, closing the entrance to France. On July 11, Jourdan entered Brussels; on July 16, he won a crushing victory before Louvain and the same day Namur opened its gates. On July 23, Pichegru, driving the English before him, seized Antwerp. No Frenchman could longer doubt that France was delivered, and with that certainty the Terror ended without a blow. Eventually the end must have come, but it came instantly, and, according to the old legend, it came through a man's love for a woman.
