It was not until October 22 that the convention, to regulate the conditions under which France and England were to apply coercion to Holland, was signed in London. The French government chafed impatiently at this delay, for which King William's reluctance to agree to the measures advocated by his ministers was chiefly responsible. Notwithstanding Talleyrand's[257] explanations of the delicate situation in which Lord Grey was placed, the Duc de Broglie, on October 21, informed Lord Granville that his government could wait no longer. The very existence of the Cabinet, he assured him, was at stake. Unless he were to be in a position to announce to the Chambers, which were about to reassemble, that definite steps were to be taken in order to expel the Dutch from Antwerp, he and his colleagues would assuredly be driven from office. If no news were received from London within the next twenty-four hours, the Cabinet, he had no doubt, would resolve to march an army against Antwerp, in the event of the King of the Netherlands refusing to comply with a summons to evacuate the citadel. This resolution would, however, be at once transmitted to London, and would be kept entirely secret until the British government should have had time to reply to it. But, to the great joy of Louis Philippe and his ministers, the arrival, on October 29, of the convention signed in London relieved them from the necessity of deciding upon their course of action, without having previously obtained the concurrence of the English government.[258] By the terms of the convention of October 22, 1832, the King of the Netherlands was to be summoned to enter into an engagement by November 2 to withdraw his troops, before the 12th of the same month, from the territory which the separation treaty had adjudged to Belgium. Should he refuse to comply, France and England agreed to lay an embargo upon the Dutch shipping within their respective harbours, to order their cruisers to seize all Dutch vessels at sea, and to blockade the coast of Holland with their combined fleets. If, by November 15, the required evacuation should not yet have taken place, a French army would enter Belgium. But its operations were to be limited strictly to the capture of the citadel of Antwerp and the forts dependent upon it, and, when this result should have been attained, it was to withdraw immediately. At the same time, a note was to be addressed to the government at Brussels calling for the evacuation of Venlo and those places still occupied by Belgium, which, under the provisions of the separation treaty, had been assigned to Holland.[259] This demand, however, would be of a purely formal character, and was to be made upon the understanding that it need only be complied with, should the King of the Netherlands agree to the concessions required of him.[260]
