whereupon the assembly testified its confidence in Narbonne. De Lessart having incurred its anger by the tameness of his replies to Austrian dictation, the Assembly voted his impeachment. War declared against Austria. The king, seeing no other course open, formed a new ministry which was chiefly Girondin. Roland became minister of the interior, Claviere of finance, De Grave of war, and Lacoste of marine. Far abler and more resolute than any of these men was Dumouriez, the new minister for foreign affairs. A soldier by profession, he had been employed in the secret diplomacy of Louis XV. and had thus gained a wide knowledge of international politics. He stood aloof from parties and had no rigid principles, but held views closely resembling those of Narbonne. He wished for a war with Austria which should restore some influence to the crown and make himself the arbiter of France. The king bent to necessity, and on the 20th of April came to the Assembly with the proposal that war should be declared against Austria. It was carried by acclamation. Dumouriez intended to begin with an invasion of the Austrian Netherlands. As this would awaken English jealousy, he sent Talleyrand to London with assurances that, if victorious, the French would annex no territory. It was designed that the French should invade the Netherlands at three points simultaneously. Lafayette was to march against Namur, Biron against Mons, and Dillon against Tournay. But the first movement disclosed the miserable state of the army. Smitten with panic, Dillon's force fled at sight of the enemy, and Dillon, after receiving a wound from one of his own soldiers, was murdered by the mob of Lille. Biron was easily routed before Mons. On hearing of these disasters Lafayette found it necessary to retreat. This shameful discomfiture quickened all the suspicion and jealousy fermenting in France. De Grave had to resign and was succeeded by Servan. The Austrian forces in the Netherlands were, however, so weak that they could not take the offensive. Austria demanded help from Prussia under the recent alliance, and the claim was admitted. Prussia declared war against France, and the duke of Brunswick was chosen to command the allied forces, but various causes delayed action. Austrian and Prussian interests clashed in Poland. The Austrian government wished to preserve a harmless neighbour. The Prussian government desired another partition and a large tract of Polish territory. Only after long discussion was it agreed that Prussia should be free to act in Poland, while Austria might find compensation in provinces conquered from France. Emeute of the 20th of June 1792.
