But the French military preparations decided him, a few days later, to make war, unless every one of the Austrian demands should be conceded by August 10th. His counsellors had already come to that conclusion, as our records prove. On July 20th Stadion wrote to Cathcart urging him to give pecuniary aid to General Nugent, who would wait on him to concert means for rousing a revolt against Napoleon in Tyrol and North Italy; and our envoy agreed to give £5,000 a month for the "support of 5,000 Austrians acting in communication with our squadron in the Adriatic." This step met with Metternich's approval; and, when writing to Stadion from Prague (July 25th), he counselled Cathcart to send a despatch to Wellington and urge him to make a vigorous move against the south of France. He (Metternich) would have the letter sent safely through Switzerland and the south of France direct to our general.[339] With the solemn triflings of the Congress we need not concern ourselves. The French plenipotentiaries saw clearly that their master "would allow of no peace but that which he should himself dictate with his foot on the enemy's neck." Yet they persevered in their thankless task, for "who could tell whether the Emperor, when he found himself placed between highly favourable conditions and the fear of having 200,000 additional troops against him, might not hesitate; whether just one grain of common sense, one spark of wisdom, might not enter his head?" Alas! That brain was now impervious to advice; and the young De Broglie, from whom we quote this extract, sums up the opinion of the French plenipotentiaries in the trenchant phrase, "the devil was in him."[340] But there was method in his madness. In the Dresden interview he had warned Metternich that not till the eleventh hour would he disclose his real demands. And now was the opportunity of trying the effect of a final act of intimidation. On August 4th he was back again in Dresden: on the next day he dictated the secret conditions on which he would accept Austria's mediation; and, on August 6th, Caulaincourt paid Metternich a private visit to find out what Austria's terms really were. After a flying visit to the Emperor Francis at Brandeis, the Minister brought back as an ultimatum the six terms drawn up on June 7th (see p. 316); and to these he now added another which guaranteed the existing possessions of every State, great or small.
