Immediately on the rejection of his terms Frederick William concluded a treaty with Alexander on the 28th of February, and Austria was invited to join the league. Alexander had joined his army himself on the 22nd of December, and had marched along with it through that horrible winter. On the 1st of March Prussia concluded its alliance with Alexander, offensive and defensive. On the 15th Alexander arrived at Breslau, and there was an affecting meeting of the two sovereigns, who had been placed in outward hostility by the power of Buonaparte, but who had never ceased to be friends at heart. The King of Prussia was moved to tears. "Courage, my brother," said Alexander; "these are the last tears that Napoleon shall cause you."
Fox had now to attempt that accommodation with Buonaparte which, he had so long contended, was by no means difficult. An opportunity was immediately offered him for opening communications with the French Government. A Frenchman, calling himself Guillet de la Gevrillire, made his way secretly into England, and solicited an interview with Fox on a matter of high importance. Fox granted it, and was indignant at discovering that it was a proposal to assassinate Napoleon. Fox ordered the man to be detained, and wrote at once to Talleyrand, informing him of the fact, and expressing his abhorrence of it. Talleyrand replied, complimenting Fox on the[517] nobleness of his principles, and expressing the admiration of the Emperor of it. "Tell him," said Buonaparte, as reported by Talleyrand, "that in this act I recognise the principles of honour and virtue in Mr. Fox;" and he added that the Emperor desired him to say, that whatever turn affairs might now take, whether this useless war, as he termed it, might be put an end to or not, he was perfectly confident that there was a new spirit in the British Cabinet, and that Fox would alone follow principles of beauty and true greatness. These empty compliments made no way towards such a negotiation as a real burst of gratitude might have introduced, especially when accompanied by such confidence as Buonaparte avowed in Fox's sentiments; and shrewd men suspected that Gevrillire had most likely been dispatched by Napoleon himself, through Fouch, to test the reality of Fox's formerly asserted indignation that Pitt, or any British Minister, could be suspected of plans of assassination against the French Emperor.
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.When the subsidy to Hesse-Cassel was sent home to receive the signatures of the Cabinet, it was found to amount to an annual payment by England of one hundred and fifty thousand crowns, besides eighty crowns to every horseman, and thirty crowns to every foot soldier, when they were really called out to service. That to Russia was immensely greater; then came in prospective that to Saxony, to Bavaria, etc. These latter States had been fed all through the last few years for doing nothing, and now demanded vastly higher terms. Yet when the Hessian Treaty was laid on the Council table by the compliant Newcastle, Ministers signed it without reading it. Pitt and Fox, however, protested against it; and when the Treasury warrants for carrying the treaty into execution were sent down to Legge, the Chancellor of the Exchequer, he refused to sign them.Savary accompanied Ferdinand to conduct him safely into the snare. He spoke positively of meeting Napoleon at Burgos; but when they arrived there, they received the information that Napoleon was only yet at Bordeaux, about to proceed to Bayonne. Savary seemed so sure of his victim, that he ventured to leave Ferdinand at Vittoria, and went on to see Napoleon and report progress; probably, also, to receive fresh instructions. The opportunity was not lost by some faithful Spaniards to warn Ferdinand to make his escape during Savary's absence, and to get into one of his distant provinces, where he could, at least, negotiate with Napoleon independently. Ferdinand was astounded, but persuaded himself that Napoleon could not contemplate such treachery. Although the people opposed the Prince's going, Savary prevailed, and on they went.
