THREE:Far more serious than this smallest of little wars was the crisis that had simultaneously overtaken the Levant. For years the Turkish Empire had been on the brink of dissolution, partly through its own weakness, partly through the ambition of Mehemet Ali, the Pasha of Egypt. In 1838 he had been prevented only by a vigorous remonstrance of Lord Palmerston's from declaring himself independent and attacking the Turkish army on the Euphrates. For months the two forces stood face to face, and then the Turks by their own folly provoked the catastrophe. Disregarding the advice of the French and British Governments, the Sultan Mahmoud sent his troops across the river. On the 24th of June, 1839, they were cut to pieces by the Egyptians, on the 29th the Sultan died, on the 30th the Turkish admiral Achmet Pasha sailed off to Alexandria, and handed over his fleet to Mehemet Ali. It was evident that prompt intervention of the Powers could alone preserve the Ottoman Empire from disintegration. But, as soon as Lord Palmerston broached the subject, the French Government refused to take part in a general agreement for the maintenance of the Porte; in fact, its sympathies were openly expressed on the side of the Pasha. Thereupon Lord Palmerston resolved to proceed without Louis Philippe. His overtures to the Russians were cordially received; Austria raised no objections. On the 15th of July, 1840, the Quadrilateral Treaty was signed, by which the British, Austrian, Prussian, and Russian representatives on the one hand, and the Turkish ambassador on the other, bound themselves to compel the Pasha to yield half of Syria to the Porte, and pledged themselves to use force to give effect to their demands.
