In this most interesting correspondence, Napoleon, the plebeian general, speaks with the dignity and the authority of a sovereign; with a natural, unaffected tone of command, as if accustomed from infancy to homage and empire. The brother of the king is compelled to look upward to the pinnacle upon which transcendent abilities have placed his antagonist. The conquering Napoleon pleads for peace; but Austria hates republican liberty even more than war. Upon the rejection of these proposals the thunders of Napoleon's artillery were again heard, and over the hills and through the valleys, onward he rushed with his impetuous troops, allowing his foe no repose. At every mountain gorge, at every rapid river, the Austrians stood, and were slain. Each walled town was the scene of a sanguinary conflict, and the Austrians were often driven in the wildest confusion pell-mell with the victors through the streets. At last they approached another mountain range called the Stipian Alps. Here, at the frightful gorge of Neumarkt, a defile so gloomy and terrific that even the peaceful tourist can not pass through it unawed, Charles again made a desperate effort to arrest his pursuers. It was of no avail. Blood flowed in torrents, thousands were slain. The Austrians, encumbered with baggage-wagons and artillery, choked the narrow passages, and a scene of indescribable horror ensued. The French cavalry made most destructive charges upon the dense masses. Cannon balls plowed their way through the confused ranks, and the Austrian rear and the French van struggled, hand to hand, in the blood-red gorge. But the Austrians were swept along like withered leaves before the mountain gales. Napoleon was now at Leoben. From the eminences around the city, with the telescope, the distant spires of Vienna could be discerned. Here the victorious general halted for a day, to collect his scattered forces. Charles hurried along the great road to the capital, with the fragments of his army, striving to concentrate all the strength of the empire within those venerable and hitherto impregnable fortifications.
