He hopes that I may be forced to accept his offers, which hitherto I have refused, and take up my abode at the court of Prussia. He hopes to gain me by losing me in France; but I swear to you I would rather live in a Swiss village than gain at this price the dangerous favour of a king." After some delay, occasioned by the journeys of the king of Prussia, during which time Voltaire did good service for his court at the Hague, he arrived at Berlin, and was warmly welcomed. Fêtes, operas, suppers--all the amusements that Frederic could command, were put in requisition to please the illustrious and favoured guest. In the midst of these, the secret negotiation advanced. Voltaire had infinite tact, and could, like many of his countrymen, mingle the most serious designs with frivolous amusements, and pursue undeviatingly his own interests, while apparently given up to philosophical disquisitions or witty discussions. In the midst, therefore, of easy and jocular conversation, Voltaire discovered the real state of things, which consisted in the king of Prussia's desire to embroil Louis XV. with England. "Let France declare war against England," said Frederic, "and I march." This sufficed for the subtle emissary. He returned to Paris, and negotiations ensued which terminated in a new treaty between France and Prussia, and the following spring Frederic invaded Bohemia with a hundred thousand men. Voltaire, however, reaped no benefit from his zeal. The king's mistress, the duchess de Châteauroux, was angry that she had not been consulted. She managed to obtain the dismission of M. Amelot, secretary for foreign affairs, under whose direction Voltaire had acted, and he was enveloped in the disgrace, that is to say, he gained no court smiles, nor any solid compensation, for his trouble.
