The Hodh and the Mauritanian Coast The Baydan Tribes in the Hodh and the Mauritanian Coast 44 Natural, they descended towards the Hodh region, and their members improvised there for many years, and finally returned The region, it was looking for found what they find there today. Thus, we find that the tribe of Tirmiz al-Sharq, or the current Tirmiz, spread between Affakibeen and Azawad, has Finally settled in that region at the end of the eighteenth century, and at that time found themselves under the control of the Braibish, who used to migrate north of Timbuktu, and pay a contribution to the tribe of [the cities of the Tuareg] through the two tribes of Kalanṣar, residing in Bankiyur, and the tribe of Katawal [Tuareg], settled in Dawane. Although the region was fertile enough to allow everyone to live together, they soon split, and a branch, Ahl Manbarak wa al-Tuktu Bukthana, moved, while another branch joined the Braibish, which is Ahl Abi; and it is said that these alliances were made based on the advice of [Sheikh] Sidi al-Mukhtar al-Kabir. As for the other branch, known as Tirmiz al-Gharb - who were under the leadership of Khalifa bin Ubayd al-Siddiq al-Fikr, who led the general migration, then his son Sheikh, then al-Siddiq bin al-Sheikh - they maintained their autonomy throughout the nineteenth century, and refused to integrate into the Braibish, who offered them that, and they were then compelled, at least, to accept a customary alliance in the Great Sahara, which would oblige Tirmiz to participate in paying the blood money of the Braibish and also in paying the tax they presented to the cities. When Tirmiz al-Gharb refused, Sidi Muhammad [bin] Mas'ud took from them in Arawan two camels, and sixty loads of salt, and immediately al-Siddiq prepared a campaign and took three hundred camels from the Braibish. These, in their extreme anger, in turn formed a convoy of 400 rifles, and despite the benevolent intervention of (Muhammad) l (Nkunah, chief of Kalanṣar, they surrounded the camps of Tirmiz and seized all their possessions. But al-Siddiq immediately gathered all those capable of bearing arms in his tribe, as well as some men from Awlad 'Allush from the Manẓarah branch, and pursued the Braibish. A great battle ensued in which Tirmiz recovered their possessions, and seized 200 camels and 200 rifles. On the side of the Braibish, 30 were killed, while Tirmiz suffered only one wounded. The following year, Sidi Muhammad bin Mahd tried to avenge his defeat, and organized a counter-raid, which he personally supervised, but he was surprised by Tirmiz and Awlad 'Allush, who were allied at the site of Buziriyah, south of Affakiyin, and this time he also lost a hundred men, and his enemies plundered him of 300 riding camels. Twelve prominent men of the Braibish perished in this melee, including Dahman, the father of Mahmud, the current chief of the tribe.
