Napoleon repaired the fortifications of Klagenfurt, and converted it into a respectable place of arms, where he established his headquarters. In a space of scarce twenty days, he had defeated the Austrians in ten combats, in the course of which Prince Charles had lost at least one-fourth of his army. The French had surmounted the southern chain of the Julian Alps; the northern line could, it was supposed, offer no obstacle sufficient to stop their irresistible general; and the Archduke, the pride and hope of the Austrian armies, had retired behind the river Mehur, and seemed to be totally without the means of covering Vienna. There were, however, circumstances less favourable to the French, which require to be stated. When the campaign commenced, the French general Joubert was posted with his division in the gorge of the Tyrol above Trent, upon the same river Levisa, the line of which had been lost and won during the preceding winter. He was opposed by the Austrian generals Kerpen and Laudon, who, besides some regular regiments, had collected around them a number of the Tyrolese militia, who among their own mountains were at least equally formidable. They remained watching each other during the earlier part of the campaign; but the gaining of the battle of the Tagliamento was the signal for Joubert to commence the offensive. His directions were to push his way through the Tyrol to Brixen, at which place Napoleon expected he might hear news of the advance of the French armies from the Rhine, to co-operate in the march upon Vienna. But the Directory, fearing perhaps to trust nearly the whole force of the Republic in the hands of a general so successful and so ambitious as Napoleon, had not fulfilled their promises in this respect. The army of Moreau had not as yet crossed the Rhine.
