At the time of M. Thiers' resignation, his despatch of October 8 was still unanswered. But, before M. Guizot had been long installed at the Foreign Office, he received Lord Palmerston's reply to it. The contents of this document caused him the greatest irritation. After exposing with remorseless logic the fallacies of M. Thiers' arguments, Palmerston laid down the principle that the future government of Egypt concerned the Porte alone. He has generally been blamed for not employing a more conciliatory tone in this, his first important communication with M. Guizot, who was not responsible for the opinions of his predecessor in office. Palmerston, however, had two distinct objects in view, and it is open to question whether he would have attained his ends, had he employed less uncompromising language. His despatches, both of November 2 and November 20, were clearly written with the purpose of convincing M. Guizot of the necessity of regarding Syria as altogether lost to Mehemet Ali, and of thus putting an end to the efforts which were being made to preserve for him the southern portion of Palestine. Secondly, by intimating that the Pasha's reinstatement in the government of Egypt would depend upon his prompt compliance with the Sultan's demands, Palmerston evidently intended to force M. Guizot to exert all his influence over Mehemet Ali in favour of a complete surrender.[663] Events, meanwhile, had been moving rapidly in Syria. Before the middle of October the Turkish flag waved once more over Beyrout and Saïda, the ancient Sidon, whilst Napier, at the head of a Turkish division and some detachments of British and Austrian marines, completely defeated and put to flight the redoubtable Ibrahim. As early as October 5, Palmerston had desired the Lords of the Admiralty to advise Sir Robert Stopford of the importance of promptly restoring the fortress of Acre to the Sultan.[664] The allied commanders appear to have been somewhat undecided as to the propriety of attacking this famous stronghold, the key of Syria. In view of the lateness of the season, Stopford himself was very reluctant to embark upon operations against it.[665] But Palmerston's despatch overcame his irresolution and induced him to listen to the bolder counsels of Napier, Walker, and Jochmus. Acre, which had successfully resisted Bonaparte and which had held Ibrahim in check for six months, surrendered, on November 3, to the British admiral after an engagement of a few hours' duration. The moment the news reached London, Stopford was directed to send "a competent officer" to Mehemet Ali to signify to him that, provided he would restore the Turkish fleet and give an undertaking in writing to evacuate Syria, Adana, Arabia, the Holy Cities and Crete, the Powers would recommend the Porte to reappoint him to the governorship of Egypt.[666] But, before these instructions could take effect, Napier, who had arrived off Alexandria with his squadron, had seen fit to
