The French believe that Ibn al-Sanusi interfered in the resistance activities in Algeria. Dufournier says: "The Sanusiya is responsible for all the resistance activities that took place against France in Algeria, and it is the cause of the various revolutions that took place against France, such as the revolution of Ahmed bin Abdallah in Tlemcen and the Algerian desert in 1844-1845, and Othman bin Takkuk in 1846." This statement and Dufournier's statement indicate that Ibn al-Sanusi participated in the battles in Algeria against the French. His role was to send money and weapons with his disciples. A copy of a letter was found, sent by one of his disciples to the Turkish governor of Ghadames. The letter indicates that Ibn al-Sanusi's call reached Algeria and that a number of his followers were fighting the French there, including Ahmed bin Abdallah. The letter is dated 1846. Ibn al-Sanusi was in the Hejaz at that time. Among its contents are: "...As for me, Abdullah, when I arrived in the land of Ouargla, God granted us victory over it, and it became Muhammadan after it was under the rule of Al-Rumi, may God destroy him, and his successor in it. Glory be to Him who strengthened the weak against the strong, and made the strong among His servants defeated and condemned. But by the blessing of the noble Sheikh Sayyid Muhammad al-Sanusi, may God be pleased with him, and may He benefit us and grant us faith in him, Amen. And the people of Ouargla and its castles, and the tribes of Sha'amiyya, and the castles of Tagourt and its Arabs, and the Al-Arba' and Al-Khazalila, and the pilgrims, and many of the Arabs of Al-Zabra and the castles of Bani Masab, are all under the obedience of God and His Messenger, and our obedience, and the mujahideen are increasing every day... And Al-Rumi, may God destroy him, sent us three camels at this hour. We met them, and we became like a white mark on a black camel. God granted us a mighty victory and made us triumph over His enemies. Fighting took place between us with gunpowder and swords until we inflicted a great defeat upon them and killed three hundred and six of them. We captured a lot of camels, countless weapons, provisions, camels, and horses. Praise be to God for that." Dufournier, quoting Al-Ashhab, p. 1.
