Even this, however, was better than the fortunes of Segur, who found himself openly flouted both by King and courtiers at Berlin. For Frederick William was still bent on a vigorous policy. On 7th February his Ministers signed with Prince Reuss, the Austrian envoy, a secret treaty of defensive alliance, mainly for the settlement of French affairs, but also with a side glance at Poland. The Prussian Ministers probably hoped for a peaceful but profitable settlement, which would leave them free for a decisive intervention in the Polish troubles now coming to a crisis; but Frederick William was in a more warlike mood, and longed to overthrow the "rebels" in France. Segur's mission to Berlin was therefore an utter failure. That of Talleyrand, on the other hand, achieved its purpose, mainly because Pitt and Grenville never had any other desire than to remain strictly neutral. It was therefore superfluous for Talleyrand to hint delicately at the desirability of the friendship of France for England, in view of the war with Tippoo Sahib in India, and the increasing ferment in Ireland.[63] On 1st March Grenville again assured him of the earnest desire of the British Government to see the end of the troubles in France, and declared that Pitt and he had been deeply wounded by the oft-repeated insinuations that they had sought to foment them. All such charges were absurd; for "a commercial people stands only to gain by the freedom of all those who surround it." We may reasonably conclude that these were the words of Pitt; for they recall that noble passage of the "Wealth of Nations": "A nation that would enrich itself by trade is certainly most likely to do so when its neighbours are all rich, industrious, and commercial nations."[64] For the rest, Grenville defied the calumniators of England to adduce a single proof in support of their slanders, and requested Talleyrand to remain some time in England for the purpose of observing public opinion. He warned him, however, that the Cabinet could not give an answer to his main proposal.
