In his irritation the First Consul despatched orders to Moreau, directing him to break the armistice and resume hostilities unless he regained possession of the bridges of the Rhine and the Danube by the surrender of Philipsburg, Ulm, and Ingolstadt. The Austrians then offered to treat with France on new bases. England wished to take part in the Congress, but to this the First Consul would not consent until she should sign a separate armistice and cease to make common cause with Austria.
The First Consul received intelligence of the occupation of the three garrisons on the 23d of September, the day he had fixed in his ultimatum to England for the renewal of hostilities. But for the meanwhile he was satisfied with the concessions of Austria: that power, in the expectation of being supported by England, asked her on what terms she was to treat.
During these communications with Austria M. Otto was in London negotiating for the exchange of prisoners. England would not hear of an armistice by sea like that which France had concluded with Austria by land. She alleged that, in case of a rupture, France would derive from that armistice greater advantage than Austria would gain by that already concluded. The difficulty and delay attending the necessary communications rendered these reasons plausible. The First Consul consented to accept other propositions from England, and to allow her to take part in the discussions of Luneville, but on condition that she should sign a treaty with him without the intervention of Austria. This England refused to do. Weary of this uncertainty, and the tergiversation of Austria, which was still under the influence of England, and feeling that the prolongation of such a state of things could only turn to his disadvantage, Bonaparte broke the armistice. He had already consented to sacrifices which his successes in Italy did not justify. The hope of an immediate peace had alone made him lose sight of the immense advantages which victory had given him.
Far from appearing sensible to the many proofs of moderation which the First Consul evinced, the combined insolence of England and Austria seemed only to increase. Orders were immediately given for resuming the offensive in Germany and Italy, and hostilities then recommenced.
The chances of fortune were long doubtful. After a reverse Austria made promises, and after an advantage she evaded them; but finally, fortune proved favourable to France. The French armies in Italy and Germany crossed the Mincio and the Danube, and the celebrated battle of Hohenlinden brought the French advanced posts within ten leagues of Vienna. This victory secured peace; for, profiting by past experience, the First Consul would not hear of any suspension of arms until Austria should consent to a separate treaty. Driven into her last intrenchments, Austria was obliged to yield. She abandoned England; and the English Cabinet, in spite of the subsidy of 2,000,000 sterling, consented to the separation. Great Britain was forced to come to this arrangement in consequence of the situation to which the successes of the army of Moreau had reduced Austria, which it was certain would be ruined by longer resistance.
