None of these plans succeeded. The Khedive recognized the futility of dismissing a Ministry that insisted on remaining in power. Mahmoud Sami replied that the Ministry would not retire so long as the squadrons were kept at Alexandria, and Arabi declared that he must refuse either to retire from his position, or to leave the country. On the 25th May, the representatives of England and France handed to Mahmoud Sami, as President of the Council of Ministers, an ultimatum in the form of a Dual Note, demanding the retirement of Arabi from the country, the withdrawal of "the Colonels" into the interior, and the resignation of Sami's Ministry. The Note added that the two Governments would, if necessary, insist on the fulfilment of these conditions. The Ministers, on receipt of the "Dual Note," waited on the Khedive to ask his opinion as to the answer that should be given, and His Highness distinctly told them that he accepted its conditions. They urged a reference to the Porte, on which the Khedive told them that it was an internal question, and that it was strange that they, who had complained that he had failed to uphold the privileges of Egypt, should suggest such a course. On the 26th the Ministers resigned, alleging as a reason that the Khedive, in accepting the conditions of England and France, had acquiesced in foreign interference in Egypt. The Khedive promptly accepted the resignation of the Ministry, and sent for Cherif Pasha to form a new Cabinet. Cherif refused on the ground that no Government was possible while the military chiefs remained. On the 27th an event occurred in Alexandria which tended to bring matters still more to a crisis. The officers of the regiments and the police force in that city held a secret meeting, and telegraphed to the Khedive direct that they would not accept the resignation of Arabi, and gave the Khedive twelve hours to reply, after which the officers declared that they would not be responsible for public tranquillity. On receipt of this message, the Khedive summoned to his presence the chief personages of State, the principal members of the Chamber, and the head officers of the Cairo garrison, and placed the situation before them.
