As a result of these conspiracies, Sultan Muhammad Al-Sheikh launched an attack against Ottomans in western Algeria in 1550. Saadians took over Tlemcen in June 9-1550, but they failed entering Mostaganem and retreated due to raids by the Prince of Banu Rashid, who are the allies of Spaniards in Oran, against them. The Saadians lost Tlemcen in January 1551 to the Ottomans, and Tlemcen became part of the Ottomans property in Algeria.
