From later times detailed accounts of a like kind are lacking; we can only follow out in some measure the general course of the Roman work of pacification. The tribes to the south of Aures were, if not extirpated, at any rate ejected and transplanted into the northern districts; so in particular the Musulamii themselves,[282] against whom an expedition was once more conducted under Claudius. The demand made by Tacfarinas to have settlements assigned to him and his people within the civilised territory, to which Tiberius, as was reasonable, only replied by redoubling his exertions to annihilate the daring claimant, was supplementarily after a certain measure fulfilled in this way, and probably contributed materially to the consolidation of the Roman government. The camps more and more enclosed the Aurasian mountain-block. The garrisons were pushed farther forward into the interior; the headquarters themselves moved under Trajan away from Theveste farther to the west; the three considerable Roman settlements on the northern slope of the Aures, Mascula (Khenschela), at the egress of the valley of the Arab and thereby the key to the Aures mountains, a colony at least already under Marcus and Verus; Thamugadi, a foundation of Trajan’s; and Lambaesis, after Hadrian’s day the headquarters of the African army, formed together a settlement comparable to the great military camps on the Rhine and on the Danube, which, laid out on the lines of communication from the Aures to the great towns of the north and the coast Cirta (Constantine), Calama (Gelma), and Hippo regius (Bonah), secured the peace of the latter. The intervening steppe-land was, so far as it could not be gained for cultivation, at least intersected by secure routes of communication. On the west side of the Aures a strongly occupied chain of posts which followed the slope of the mountains from Lambaesis over the oases Calceus Herculis (el Kantara) and Bescera (Beskra), cut off the connection with Mauretania. Even the interior of the mountains subsequently became Roman; the war, which was waged under the emperor Pius in Africa, and concerning which we have not accurate information, must have brought the Aurasian mountains into the power of the Romans. At that time a military road was carried through these mountains by a legion doing garrison duty in Syria and sent beyond doubt on account of this war to Africa, and in later times we meet at that very spot traces of Roman garrisons and even of Roman towns, which reach down to Christian times; the Aurasian range had thus at that time been occupied, and continued to be permanently occupied. The oasis Negrin, situated on its southern slope, was even already under or before Trajan furnished by the Romans with troops, and still somewhat farther southward on the extreme verge of the steppe at Bir Mohammed ben Jûnis are found the ruins of a Roman fort; a Roman road also ran along the southern base of this range.
