No immediate change in the form of government ensued. The Committee of Public Safety, reconstituted, continued to exercise the executive functions which nominally depended upon the Convention; and the impulse which it had imparted to the soldiers and armies of France continued for a time to carry them resistlessly forward. But the delirious intensity of the popular movement had reached its climax in the three months' unrestrained power of Robespierre, with whose name it has been ever associated. Though the external manifestations of strength continued for a time unabated, the inner tension was relaxing. Weakness was about to succeed the strength of fever, to spread from the heart throughout the whole organism, and, by threatening social dissolution, to prepare the way for concentrated absolute power.
The onward swing of the French armies on the north-east still continued. The year 1794 had opened with the investment of Landrecy by the allies, and its surrender to them on the 30th of April. The French began their campaign with the plan, especially affected by Carnot in all his military combinations, of attacking at the same time both flanks of the allied Austrians, Dutch and English, concentrating at each extremity of the line a force greatly superior to the enemy before it. As Jourdan, commanding the French right, threatened the allied stronghold of Charleroi, he drew thither the greater effort of the allies, and Pichegru, on the left, found his task easier. Five times did Jourdan cross the Sambre to attack Charleroi, and four times was he compelled to re-cross; but on the fifth, before the allies could come up in sufficient force, the place capitulated,—the guns of the relieving force being heard just as the garrison was marching out. The following day, June 26, 1794, Jourdan fought and won the battle of Fleurus; the Austrians retreating upon Nivelles towards the future field of Waterloo. The allies on both flanks continued to fall back; Ostend and Nieuport, ports on the North Sea facilitating communication with England, were successively surrendered, and Brussels uncovered. On the 10th of July Pichegru entered Brussels and formed his junction with Jourdan. On the 15th the allies lost Landrecy, the first and only prize of the campaign. On the same day the French attacked in force the centre of the allied line, where the Anglo-Dutch left touched the Austrian right. The former being gradually turned fell back, and the Austrians, finding their flank uncovered, did the same. From this time the allies retired in divergent directions, the Anglo-Dutch north-east toward Holland, the Austrians eastward toward Coblentz; thus repeating in retreat the unmilitary and ruinous mistake which had rendered abortive the offensive campaign of 1793.
