Their first dealings with him were unfortunate. Desmichels arrived at Oran in the spring of 1833. Finding that he could make no headway against Abd-el-Kader, who from his capital of Mascara was preaching a holy war for the extermination of the infidels, he concluded with him a treaty which enormously increased the Arab’s authority. Abd-el-Kader was described in it as Emir; all practical power was placed in his hands; and he was permitted to purchase arms and ammunition in French towns. No mention was made of French sovereignty. The treaty, though contrary to the instructions of the French Government, was accepted by it in the belief that it assured peace. Difficulties soon arose. Desmichels was recalled; his successor, Trezel, at the head of a column of 1700 men, was attacked by Abd-el-Kader in the marshes of La Macta, and defeated with the loss of a third of his force. The prestige of this victory brought many waverers to the Arab leader’s flag. But France’s disaster brought home to her the seriousness of the position, and in the end the defeat did more towards the ultimate conquest than a victory would have done. Clauzel, who had left Africa almost in disgrace in 1831, was sent back in full command in 1835. He alone of the French generals had exhibited any military qualities. His grandiose projects have been justified by events. His main plan consisted in occupying Mascara and Tlemçen in the west, Medea and Miliana in the centre, and Constantine in the east. Of Tlemçen and Constantine he said, “Si vous n’occupez pas ces deux Gibraltar de la Régence d’Alger, vous n’en serez jamais les maîtres.” His failure was due to his attempt to effect these objects with the inadequate means with which he was supplied. He commenced by advancing against Abd-el-Kader, who retired before him. Having occupied Mascara and Tlemçen, he returned to Algiers, whereupon Tlemçen was promptly besieged by the Arabs. At this point the great Frenchman, destined to overthrow the Arab power and to conquer Algeria, appeared on the scene. General Bugeaud was sent to command in the west. He was personally opposed to conquest, and regarded French intervention in Algeria not only as having been badly conducted, but as initially a mistake. These views did not prevent him from putting his hand to the plough. He began by revolutionizing the methods of warfare; in spite of the opposition of his officers, he dispensed with heavy trains of baggage and artillery, lightened the loads of the soldiers, and carried their provisions on mules. Attacking Abd-el-Kader at La Sikkah he inflicted on him a signal defeat, his native auxiliaries pursuing the flying enemy with fury and slaughtering them in great numbers. Bugeaud then returned to France.
