Lord John's view of the situation was expressed in a memorandum which he placed before the Cabinet, and in which he came to these conclusions: 'That if Russia will not make peace on fair terms, we must appear in the field as the auxiliaries of Turkey; that if we are to act in conjunction with France as principals in the war, we must act not for the Sultan, but for the general interests of the population of European Turkey. How, and in what way, requires much further consideration, and concert possibly with Austria, certainly with France.' He desired not merely to resist Russian aggression, but also to make it plain to the Porte that we would in no case support it against its Christian subjects. The Cabinet was not prepared to adopt such a policy, and Lord John made no secret of his opinion that Lord Aberdeen's anxiety for peace and generous attitude toward the Czar were, in reality, provoking war. He believed that the Prime Minister's vacillation was disastrous in its influence, and that he ought, therefore, to retire and make way for a leader with a definite policy. The Danube, for the moment, was the great barrier to war, and both Russia and Turkey were afraid to cross it. Lord John believed that energetic measures in Downing Street at this juncture would have forestalled, and indeed prevented, activity of a less peaceful kind on the Danube. Meanwhile, despatches, projects, and proposals passed rapidly between the Great Powers, for never, as was remarked at the time by a prominent statesman, did any subject produce so much writing. Turkey--perhaps still more than Russia--was eager for war. Tumults in favour of it had broken out at Constantinople; and, what was more to the purpose, the finances and internal government of the country were in a state of confusion. Therefore, when the concert of the four Powers had been shattered, the Turks saw a better chance of drawing both England and France into their quarrel. At length, on October 10, the Porte sent an ultimatum to the commander of the Russian troops which had invaded Moldavia and Wallachia, demanding that they should fall back beyond the Pruth within fifteen days. On October 22 the war-ships of England and France passed the Dardanelles in order to protect and defend Turkish territory from any Russian attack. The Czar met what was virtually a declaration of war by asserting that he would neither retire nor act on the aggressive. Ten days after the expiration of the stipulated time, Omar Pacha, the Ottoman commander in Bulgaria, having crossed the Danube, attacked and vanquished the Russians on November 4 at Oltenitza. The Czar at once accepted the challenge, and declared that he considered his pledge not to act on the offensive was no longer binding. The Russian fleet left Sebastopol, and, sailing into the harbour of Sinope, on the southern coast of the Black Sea, destroyed, on November 30, the Turkish squadron anchored in that port, and slew four thousand men.
