Heytesbury, after prefacing his disagreeable task of communicating these instructions by assurances that his government was only desirous of tendering friendly advice to a former ally, proceeded to read out to Count Nesselrode Lord Palmerston's despatch. "The Count," he reported, "listened with great attention and in silence, but his silence was not the silence of assent." The Russian Chancellor expressed his regret that the British government should have seen fit to make representations of this nature, notwithstanding the intimation, conveyed to it by Prince Lieven, that the Tsar could not admit of foreign interference in the Polish question. The official answer of the Imperial Cabinet was in due course communicated to Palmerston by the Russian ambassador. As Heytesbury had foreseen, Nicholas, "strong in the support of Austria and Prussia and in the unanimous approbation of the Russian nation,"[169] refused to adopt the interpretation of the treaty which it was desired to place upon it in London and in Paris.
In the meantime, important progress had been made towards a settlement of the Belgian question. At the end of August, Baron Stockmar, Leopold's confidential adviser, proceeded to London to watch over his interests in conjunction with Van de Weyer, the Belgian minister at the Court of St. James'. Stockmar realized speedily that the Belgians would have to suffer for the defeat inflicted upon them by the Dutch. In the treaty of peace and separation, which the conference was resolved must be concluded without delay, they could not hope to obtain the favourable terms conceded to them in the convention of the eighteen articles. Should they refuse to agree to the necessary concessions, Palmerston warned him that the conference would be broken up, and the King of Holland would be left free to fight out his quarrel with Leopold. Stockmar, however, continually impressed upon his master that this was a threat which he could safely afford to disregard. The French had always considered the union of Holland and Belgium and the creation of the Kingdom of the Netherlands as a diplomatic combination directed against them. Public opinion in France might, therefore, be depended upon to compel the government to resist any attempt on the part of the Dutch to reconstitute the kingdom by force of arms. But, although he admitted that Leopold could only expect active assistance from France, Stockmar strongly deprecated the idea of using French intervention as a means of intimidating the conference. Such a course, he was convinced, would simply incline the four Powers to lean all the more towards Holland. Lords Grey and Palmerston were well disposed, but they had to reckon with national sentiment, which was more favourable to "England's ancient allies," the Dutch, than to the Belgians. Nevertheless, although the British government might be unable to render him practical assistance, Leopold, Stockmar considered, should strive to gain its moral support. The prolonged occupation of Belgium by the French was to be deplored, because it engendered the suspicion in London that the King was over-anxious to place himself under the protection of France. In order effectually to put a check upon both Dutch and French intrigues Leopold, in Stockmar's opinion, would be well advised to propose for the hand of a daughter of Louis Philippe.
