Instead of success came inaction, disaster, and treason. The army of Flanders lay idle during January and February for want of provisions and materials of war; and no sooner had Dumouriez opened the campaign against Holland than he was recalled by intelligence that the Austrians had fallen upon his lieutenant, Miranda, at Maestricht, and driven the French army before them. Dumouriez returned, in order to fight a pitched battle before Brussels. He attacked the Austrians at Neerwinden (March 18), and suffered a repulse inconsiderable in itself, but sufficient to demoralise an army composed in great part of recruits and National Guards. [26] His defeat laid Flanders open to the Austrians; but Dumouriez intended that it should inflict upon the Republic a far heavier blow. Since the execution of the King, he had been at open enmity with the Jacobins. He now proposed to the Austrian commander to unite with him in an attack upon the Convention, and in re-establishing monarchy in France. The first pledge of Dumouriez's treason was the surrender of three commissioners sent by the Convention to his camp; the second was to have been the surrender of the fortress of Condé. But Dumouriez had overrated his influence with the army. Plainer minds than his own knew how to deal with a general who intrigues with the foreigner. Dumouriez's orders were disregarded; his movements watched; and he fled to the Austrian lines under the fire of his own soldiers. About thirty officers and eight hundred men passed with him to the enemy. [Defeats on the North and East. Revolt of La Vendée, March, 1793.] [The Commune crushes the Gironde, June 2.]
