THREE:On such utterly unsubstantial ground did the English ministers continue this negotiation. They assured De Torcy that the Queen of England insisted on Philip's renunciation of one throne or the other, and he at length renounced that of France, everybody seeing that the sense in which he renounced it was no renunciation at all, but a pretence to get the peace effected; and thus the[4] English ministers, with their eyes open to the fraud, went on urging the Allies to come into these most delusive and unsatisfactory terms. But as the renunciation of Philip did not arrive till after midsummer, the negotiators at Utrecht continued to talk without advancing, and the armies in the field continued to look at each other without fighting.At this point the advance of the Prussians was unexpectedly checked. After the capture of Verdun, on the 2nd of September, they had spread themselves over the plains of the Meuse, and occupied, as their main centre, Stenay. Dumouriez and his army lay at Sedan and in its neighbourhood. To reach him and advance on Chalons in their way to Paris, the Allies must pass or march round the great forest of Argonne, which extends from thirteen to fifteen leagues, and was so intersected with hills, woods, and waters, that it was at that time impenetrable to an army except through certain passes. These were Chne-Populeux, Croix-aux-Bois, Grand Pr, La Chalade, and Islettes. The most important were those of Grand Pr and Islettes, which however were the two most distant from Sedan. The plan therefore was to fortify these passes; and in order to do this Dumouriez immediately ordered Dillon to march forward and occupy Islettes and La Chalade. This was effected; a division of Dillon's forces driving the Austrian general, Clairfayt, from the Islettes. Dumouriez followed, and occupied Grand Pr, and General Dubouquet occupied Chne-Populeux, and sent a detachment to secure Croix-aux-Bois between Grand Pr and Chne-Populeux.
