On August 23 the conference decided to impose an armistice upon the Dutch and Belgians, to expire on October 10.[147] The French government, however, declared that a mere undertaking by the King of the Netherlands, not to begin hostilities afresh, could not provide a guarantee for the maintenance of peace of sufficient weight to permit of the complete withdrawal of the French army. General Baudrand, moreover, was sent to London with a letter from Louis Philippe to Talleyrand, in which the King expressed his displeasure with his action in signing a document of that nature. Baudrand during his stay in England had interviews both with Grey and Palmerston.[148] He appears to have expatiated upon the outcry which would be raised in the Chamber, were France to gain neither moral nor material advantages, in return for the expense to which she had been put by her intervention in aid of the King of the Belgians. Palmerston assured him that his colleagues and himself were sincerely anxious that M. Casimir Périer should remain in office, but, he added pointedly, "when to keep in a ministry of peace it became necessary to comply with the demands of the party which was for war, it was problematical what decree of advantage was thereby to be acquired."[149] Talleyrand appears to have been little moved by the censure passed upon him. He contended that he had acted for the best, and that no fears need be entertained that the Dutch would again attack Belgium. At the same time he continued to urge the necessity of bringing the occupation of Belgium to a close. "There is more real anxiety over here than I have yet seen," he wrote on August 27. "People are all talking of an interview between the Duke of Wellington and Lord Grey." A few days later he again pleaded earnestly for evacuation, suggesting that the withdrawal of the troops might be carried out so slowly that some portion of them should still be in Belgium, at the expiration of the armistice.[150]
