Accordingly, on September 20, M. Van de Weyer officially informed the conference that he was authorized to discuss with the Dutch plenipotentiaries the points in dispute between the two countries. But in a note dated the same day, Van Zuylen, ignoring completely the _thème de Lord Palmerston_, claimed the execution of the treaty on the terms set forth in the Dutch counter proposal of June 30. The conference, thereupon, called upon him definitely to state whether he was empowered to negotiate with Belgium in accordance with the proposals submitted by the British plenipotentiary. To this demand he returned an answer which was unanimously held to be highly unsatisfactory, and, on October 1, in consequence, the representatives of the five Powers met to consider the steps which should now be taken to bring matters to a conclusion. As had been foreseen, it was clear at once that the prospects of arriving at an agreement were hopeless. According to the absolute Powers, coercion must be confined to a declaration authorizing the Belgians to withhold payment of their share of the Dutch-Belgian debt, until the citadel of Antwerp should be handed over to them. France and England, on the other hand, deriding the notion that pressure of this kind would suffice to overcome the obstinacy of the King of the Netherlands, called for the application of sterner measures. To this demand the plenipotentiaries of the northern Powers opposed the irrevocable resolution of their respective Courts not to participate in any hostile acts against Holland. In face of this irreconcilable divergence of opinion, the conference broke up, the representatives of France and England announcing the intention of their governments to take steps to ensure the prompt execution of the terms of the separation treaty.[243]
