Austria professed great friendliness to Napoleon, and he thought that she would not like to break with him on account of the Empress. But Austria, on the 27th of June, signed an engagement with Russia and Prussia, at Reichenbach, in Silesia, binding herself to break with him if he did not concede the terms which they demanded. These were to restore Illyria and the whole of Austrian Italy; to reinstate the Pope; to leave Poland to the three Powers who had formerly possessed themselves of it, and to renounce Spain, Holland, Switzerland, and the Confederation of the Rhine. Buonaparte treated these demands as sheer madness; but he was nearly mad himself when Talleyrand and Fouché, and still more, his best military counsellors, advised him at least to fall back to the left bank of the Rhine, and make that the boundary of France. He offered to annihilate the Grand Duchy of Warsaw, giving up the whole of Poland to Russia--such was his gratitude to the Poles!--to restore Illyria to Austria, but to cut down Prussia still more by pushing the Rhenish Confederation to the Oder. His terms were rejected with disdain. Yet he had a last interview with Metternich, in which he hoped to terrify him by a dread of the future preponderance of Russia; but, seeing that it made no impression, he became incensed, and adopted a very insolent tone towards the Austrian Minister. "Well, Metternich," he demanded, "how much has England given you to induce you to play this part towards me?" Metternich received the insult in haughty silence. Buonaparte, to try how far the diplomatist still would preserve his deference towards him, let his hat fall: Metternich let it lie. This was a sign that the Austrian had taken his part; it was, in fact, the signal of war. Yet, at the last moment, Napoleon suddenly assumed a tone of conciliation, and offered very large concessions. He had heard the news of the defeat of Vittoria. But it was too late. The Congress terminated on the 10th of August, and the Allies refused to re-open it. On the 12th of August, two days after the termination of the armistice, Austria declared herself on the side of the Allies, and brought two hundred thousand men to swell their ranks. This redoubtable force was commanded by her general, Prince von Schwarzenberg.
