معركة ميسلون
For France, the San Remo decision meant that most of its claims in Syria were internationally recognized and relations with Faisal were now subject to French military and economic considerations. The ability of Great Britain to limit French action was also significantly diminished. France issued an ultimatum and intervened militarily at the Battle of Maysalun in July 1920, deposing the Arab government and removing King Faisal from Damascus in August 1920. In 1920, Great Britain appointed Herbert Samuel, 1st Viscount Samuel as high commissioner and established a mandatory government in Palestine that remained in power until 1948.
