The French allowed the retreating Allies no rest. There was no want of men. The Convention, by the menace of the guillotine at home, and the promises of plunder and licence abroad, could raise any number of thousands of men, could find millions of money, and they had not a single feeling of humanity, as the streaming axes of the executioners all over the country showed. They could also fight and daunt their enemies by the same unhesitating ferocity. They had long published to all their armies that no quarter was to be given to British or Hanoverians—they were to be massacred to a man; and they now sent word to the fortresses of Valenciennes, Condé, Quesnoy, and Landrecies, that unless the garrisons surrendered every soul on their being taken should be butchered. The fortresses were immediately surrendered, for the menace was backed by one hundred and fifty thousand men—the combined troops of Pichegru and Jourdain. Besides, the fortresses in the hands of the Allies were so badly supplied both with ammunition and stores, that they were but dens of famine and impotence. On the 5th of July Ghent opened its gates to the French; on the 9th the French entered Brussels, having driven the Duke of Coburg out of his entrenchments in the wood of Soignies, near which the battle of Waterloo was afterwards fought. They next attacked the Duke of York and Lord Moira at Mechlin, and after a sharp conflict drove them thence. The very next day Clairfait was defeated and obliged to abandon both Louvain and Liége. General Beaulieu was driven out of Namur, solely because he had no provisions there for his army, though otherwise the place could have made a long defence. The Duke of York was compelled to abandon the strong and important citadel of Antwerp from the same cause, and to cross the Scheldt into Dutch territory, leaving the French to make their triumphant entry into Antwerp on the 23rd of July. Such was the brilliant campaign of the French in the Netherlands in the summer of 1794—such the ignominious defeat of the Allies, with an army of two hundred thousand men. Pitt, however, bravely struggled to keep up the Coalition. A loan of four million pounds was granted to Austria. At the same time, in addition to the Hessian soldiers engaged, the Duke of Brunswick, the king's relative, was to furnish two thousand two hundred and eighty-nine men on the same liberal terms, and was himself to have an annual allowance of sixteen thousand pounds sterling.

Those princes that did bring men into the field, such as the Hessians, Brunswickers, etc.—the Menschen-Veräufer, or man-sellers, as they were styled by their own people—were rapacious beyond example. During the American war we had employed these Hessians, Brunswickers, and the like, at a cost that excited general indignation. Besides paying seven pounds ten shillings and a penny for every man, the Duke of Brunswick, who furnished only four thousand and eighty-four men, had had an annual subsidy of fifteen thousand five hundred and nineteen pounds. The Landgrave of Hesse-Cassel, who furnished twelve thousand men, had ten thousand two hundred and eighty-one pounds a year.

It was towards the end of May before Marshal Möllendorf, the Prussian general, began the campaign. He then attacked the French, and drove them out of their entrenchments at Kaiserslautern with great slaughter. There, however, his activity seemed to cease; and on the 12th of July the French again fell upon him. He fought bravely for four whole days, supported by the Austrians; but both these Powers were compelled to retreat down the Rhine, the Prussians retiring on Mayence and the Austrians crossing the river for more safety. The French marched briskly after the Prussians, took Trèves, and then sent strong detachments to help their countrymen to make a complete clearance of Belgium and to invade Holland. Clairfait, who was still hovering in Dutch Flanders, was attacked by overwhelming numbers, beaten repeatedly, and compelled to evacuate Juliers, Aix-la-Chapelle, and finally Cologne. The French were so close at his heels at Cologne that they shouted after him that "that was not the way to Paris." Coblenz, where the Royalist Emigrants had so long made their headquarters, though strongly fortified, soon after surrendered. The stout fortress of Venloo, on the Meuse, and Bois-le-Duc, as promptly surrendered, and the French marched on Nimeguen, near which the Duke of York lay, hoping in vain to cover the frontiers of Holland. The people of Holland, like those of Belgium, were extensively Jacobinised, the army was deeply infected by French principles, and to attempt to defend such a country with a mere handful of British was literally to throw away the lives of our men. Yet the duke stood stoutly in this hopeless defence, where half Holland ought to have been collected to defend itself.

On the 19th of October the French attacked the duke with sixty thousand men, and though his little army fought with its usual dogged bravery it was compelled to give way. It did this, however, only to assume a fresh position, still covering Nimeguen, where, on the 27th, the French again attacked it, and compelled it to retire from the contest. The duke led the wreck of his army across the Waal and the Rhine, and posted himself at Arnhem in Guelderland, to throw some impediment in the path of Pichegru, who was advancing, at the command of the Convention, to reduce Holland. Nimeguen, full of Dutch traitors, soon opened its gates; Maestricht did the same to Kleber; and at the end of the campaign the gloomiest prospects hung over Holland.

In the south great successes had been won by the French. A formidable attack was made on the territories of the King of Sardinia and the position of Saorgio was turned. But another division of these French descended from the Alps. It was the month of May when General Dumas, with the army of the Alps, had forced his way through the defiles of Mont Cenis. The Piedmontese garrisons of the forts there had fled without much resistance, astonished and confounded at seeing the French appear on the loftiest heights around them. The French pursued their retreating troops as far as Susa, led on by Jacobinised Savoyards, who hated the Piedmontese. But Dumas, finding that strong forces of Piedmontese and Austrians, under the King of Sardinia and the Austrian General Wallis, were drawn up at the foot of the Alps, did not venture to descend into the plains. Another body of the army of Italy was delayed some time in the Genoese territory, whilst Buonaparte was employed in sounding the condition and intentions of the people of Genoa. All the Alpine passes were in their hands, and Italy was doomed to drink the cup of misery to the very dregs.

Whilst the French armies had been carrying bloodshed and misery into the countries around them, their brethren at home had been equally busy in pushing forward those mutual hatreds which appeared likely to end in the extermination of the whole race of revolutionists. The Girondists being destroyed, new divisions showed themselves in those who had hitherto been allies—Robespierre and his coadjutors. Hébert, Chaumette, Clootz, Ronsin, and others, began to raise their heels against their chief, and their chief doomed every one of them to the guillotine. His most important victim was Danton, a man by no means contemptible (guillotined April 5th, 1794).

Robespierre believed that there was a majority of the Republicans who thought they had gone too far in abolishing the Deity and setting up the Goddess of Reason. He declared that the people needed festivals, and immediately it was decreed that every decade should be celebrated as a festival. A festival in honour of the Supreme Being inaugurated this series of special holidays, and it was to be followed by festivals to the Human Race, the French People, the Love of Country, Agriculture, Necessity, Misfortune, Posterity, and various other qualities and sentiments, each having one decade in the year. The first festival to the Supreme Being was fixed for the 20th of Prairial, or 8th of June. The painter David was commissioned to prepare the scenes and ceremonies of the festival, which was enacted in the gardens of the Tuileries. Robespierre, in his sky-blue coat and most showy waistcoat, and carrying in his hand a grand bouquet of flowers mixed with ears of wheat, led the procession and officiated as high priest. But though Robespierre had proclaimed the reign of the Supreme Being, he had not the least intention that it should on that account be any the more a reign of mercy. In his speech at the festival of the Supreme Being, he declared that the Republic must be still further purged—that they must remain inexorable. On this point he and all his colleagues were agreed, but they were agreed in nothing else. They immediately broke into fresh schisms, as would necessarily be the case with such men, who must go on exterminating one another to the last. Robespierre, St. Just, and Couthon still hung together; but Barrère, Collot d'Herbois, Billaud-Varennes, and most of the other members of the Committees of Public Welfare and Public Safety, were in the very act of rushing into opposition, and beginning a struggle with the triumvirate—Robespierre, Couthon, and St. Just—to the death. St. Just advised Robespierre to anticipate them, but he, relying on his authority with the Convention, remained inactive. It was a fatal mistake. Barrère and his faction determined to strike a decisive blow at Robespierre; and Tallien volunteered to commence the attack on Robespierre in the Convention. To Robespierre's utter astonishment, his friends were outnumbered, and decrees were immediately passed for the arrest of Couthon, Lebas, St. Just, Robespierre and his brother. He escaped and fled to the Commune. For a moment it seemed as if a revolution would have restored him to power. But the Parisians were weary of their tyrant, and on the following day Robespierre with twenty members of the Commune perished on the scaffold (July 28th, 1794).

No sooner had Collot d'Herbois, Barrère, and that party triumphed over Robespierre than they summoned the members of the tribunal to their bar—ay, on the very morning of the day of his execution—and voted them honours amid much applause. The tribunal replied, that though a few traitors like Coffinhal and Dumas had found their way into the tribunal, the majority of them were sound and devoted to the Convention. Accordingly, the next day the Convention handed over to Fouquier-Tinville and his colleagues a list of fresh proscriptions of sixty-nine municipals, and a few days afterwards—namely, the 12th of Thermidor, being the 30th of July—they added twelve more, completing eighty-one victims! These were all executed within twenty-four hours. The Convention then fell into new divisions, some members contending for its being time to cease these tragedies, others insisting on maintaining them. Billaud-Varennes, Barrère, and Collot d'Herbois defended the guillotine and Fouquier-Tinville, but the greater number of the enemies of Robespierre denounced them, declared themselves the overthrowers of Robespierre, and assumed the name of Thermidorians, in honour of the month in which they had destroyed him. For the Thermidorians saw that the better part of the public had become sick of blood, and they set about contracting the Reign of Terror. They reduced the powers of the two governing Committees; they decreed that one-fourth of the members should go out every month; they reduced the revolutionary sections of Paris from forty-eight to twelve, and abolished the forty sous a day to the sansculotte patriots for their attendance. A month after the execution of Robespierre, Tallien made a fierce onslaught on the Terrorist system, and declared that there were numbers yet living who had been equally merciless with Robespierre, Couthon, and St. Just; and the next day Lecointre denounced by name Barrère, Billaud-Varennes, and Collot d'Herbois. To put an end to the Jacobin resistance, the Convention closed the Jacobin Club altogether, which had thus only survived the fall of Robespierre about four months. Thereupon the Jacobins began to denounce the Thermidorians as anti-Republicans, but they retorted that they were Republicans of the purest school—that of Marat.
