In 1271, Baibars' forces seized al-'Ullaiqah and ar-Rusafa, after taking Masyaf the year before. Later in the year, Shams ad-Din surrendered and was deported to Egypt. Qala'at al-Khawabi fell that year and within two years Gerdkuh and all of the Assassin fortresses were held by the sultan. With the Assassins under his control, Baibars was able to use them to counter the forces arriving in the Ninth Crusade. The sultan threatened Bohemond VI, and the Assassins attacked future king Edward I of England unsuccessfully.
