The defeat and treason of Dumouriez brought the army of Austria over the northern frontier. Almost at the same moment Custine was overpowered in the Palatinate; and the conquests of the previous autumn, with the exception of Mainz, were lost as rapidly as they had been won. Custine fell back upon the lines of Weissenburg, leaving the defence of Mainz to a garrison of 17,000 men, which, alone among the Republican armies, now maintained its reputation. In France itself civil war broke out. The peasants of La Vendée, a district destitute of large towns, and scarcely touched either by the evils which had produced the Revolution or by the hopes which animated the rest of France, had seen with anger the expulsion of the parish priests who refused to take the oath to the Constitution. A levy of 300,000 men, which was ordered by the Convention in February, 1793, threw into revolt the simple Vendeans, who cared for nothing outside their own parishes, and preferred to fight against their countrymen rather than to quit their homes. The priests and the Royalists fanned these village outbreaks into a religious war of the most serious character. Though poorly armed, and accustomed to return to their homes as soon as fighting was over, the Vendean peasantry proved themselves a formidable soldiery in the moment of attack, and cut to pieces the half-disciplined battalions which the Government sent against them. On the north, France was now assailed by the English as well as by the Austrians. The Allies laid siege to Condé and Valenciennes, and drove the French army back in disorder at Famars. Each defeat was a blow dealt to the Government of the Gironde at Paris. With foreign and civil war adding disaster to disaster, with the general to whom the Gironde had entrusted the defence of the Republic openly betraying it to its enemies, the fury of the capital was easily excited against the party charged with all the misfortunes of France. A threatening movement of the middle classes in resistance to a forced loan precipitated the struggle. The Girondins were accused of arresting the armies of the Republic in the midst of their conquests, of throwing the frontier open to the foreigner, and of kindling the civil war of La Vendée. On the 31st of May a raging mob invaded the Convention. Two days later the representatives of France were surrounded by the armed forces of the Commune; the twenty-four leading members of the Gironde were placed under arrest, and the victory of the Mountain was completed.
