The operations of the international coalition against Mehemet Ali of Egypt had now begun. Though the Viceroy's soldiers lay on Turkish soil without a foe before them, and France stood at his back, Mehemet Ali found himself checkmated. While Russia undertook to keep Ibrahim's army out of Constantinople, all French support was neutralized by Germany's mobilization on the Rhine. A naval squadron, composed of British and Austrian warships, was free to land the Turkish forces in Syria. On October 10, Commodore Napier bombarded Beyrout. The Syrians were armed against their Egyptian oppressors. On November 3, the British and Austrian fleets captured Acre. Ibrahim, with the remains of his army, fell back toward the Egyptian frontier. When the British fleet arrived before Alexandria, Mehemet Ali made haste to come to terms. In contravention of the ultimatum of the Powers, he was allowed to retain his hereditary dominion over Egypt upon relinquishment of Syria, and of the Turkish fleet, which had been betrayed into his hands. Sir Charles Napier in later years, while speaking of his part in this expedition in Parliament, said: "I was ashamed for my country and for myself." [Sidenote: Fall of Thiers' Ministry] [Sidenote: Oriental affairs readjusted] The humiliating position forced upon France caused the downfall of the Ministry of Thiers. Marshal Soult was placed at the head of affairs. Guizot was recalled from his embassy at London to take the portfolio of Foreign Affairs. He succeeded in restoring France to her former place in the concert of Europe. The French Government joined with the other powers in the restoration of the ancient rule of the Ottoman Empire by which all foreign warships were excluded from the Bosphorus and the Dardanelles. Russia thereby virtually conceded the abrogation of her treaty of Unkiar Skelessi. On the other hand, Sebastopol and the Russian arsenals of the Euxine were thus safeguarded against any maritime attack except by Turkey. [Sidenote: Napoleon's body returned]
