This was not the case, as Cavour himself soon found out.
After his visit to Plombieres, Cavour had hurried across the frontier and spent two days at Baden-Baden, where he met the Prince of Prussia, Manteuffel, who was still Minister, and other German statesmen.

Bismarck had been at Baden-Baden in the previous week and returned a few days later; he happened, however, on the two days when Cavour was there, to be occupied with his duties at Frankfort; the two great statesmen therefore never met.

Cavour after his visit wrote to La Marmora saying that he had been extremely pleased with the sympathy which had been displayed to him, both by the Prince and the other Prussians.

So far as he could foresee, the attitude of Prussia would not be hostile to Italian aspirations.

In December, however, after the change of Ministry, he writes to the Italian Envoy at Frankfort that the language of Schleinitz, the new Foreign Minister, is less favourable than that of his predecessor.
