Conquest of Algeria

The capture of Algiers was the culmination of the French military expedition of 1830 in North Africa. After establishing a solid bridgehead at Sidi Ferruch, French troops advanced toward the Ottoman capital of the Regency of Algiers. On 4 July, after several pitched battles and intense artillery bombardment of Turkish fortifications, the French launched the final assault. On 5 July Dey Hussein capitulated. This major victory marked the effective beginning of French colonial domination in Algeria. It was widely publicized in France, though overshadowed a few days later by the July Revolution.

The Battle of Macta was a decisive ambush inflicted by Emir Abdelkader on French troops commanded by General Trézel. After fruitless negotiation attempts with Abdelkader, the French withdrew from Mascara toward Mostaganem. Crossing the Macta marshes, the French column was surprised and harassed by Arab cavalry. Outnumbered, overwhelmed by heat and mud, the French lost control of their formation and were cut to pieces in a rapid assault. It was Abdelkader's first major victory over French colonial forces.

The first French attempt to seize the fortified city of Constantine ended in bitter failure. Marshal Clausel, Governor General of Algeria, launched an ambitious expedition to break resistance of Ahmed Bey, last major independent bastion of eastern Algeria. Despite initial advance from Bône, French troops suffered from bad weather, lack of supply, and fierce resistance. The final assault on the walls failed. The column was forced into disorganized retreat in the rain, harassed by local forces.

The second expedition against Constantine, conducted one year after Clausel's failure, was better prepared and crowned with success. General Damrémont meticulously organized approach to the city. After his premature death, General Valée took command and directed the final assault. French troops managed to breach fortifications after intense bombardment. Constantine fell after two days of fierce fighting, marking a turning point in French conquest of eastern Algeria.

Shortly after capture of Constantine, General Changarnier led a punitive expedition against Kabyle tribes of Djebel Bou Taleb suspected of aiding Ahmed Bey. The expedition turned into pitched battle in the mountains, where French troops faced a coalition of Kabyle warriors. Although initially surprised, they managed to reverse the situation and won after several hours of difficult fighting in steep terrain.

The Battle of Collo opposed a French expeditionary column to a Kabyle tribal coalition on Algeria's east coast. Colonel Schauenburg, charged with securing Collo port and its strategic surroundings, faced a well-organized ambush in steep terrain. Thanks to coordinated maneuver between land troops and naval support from the bay, French forces achieved decisive defeat of the insurgents.

The Battle of the Oued Bou-Sellam marked new stage in pacification of northern Constantinois. French troops led by General Gentil attacked coalition of Kabyle tribes entrenched on heights bordering the oued. Rugged terrain and fierce mountaineer resistance made engagement particularly difficult, but coordinated use of artillery and mountain infantry allowed decisive victory.

This battle opposed French forces to coalition of mountain tribes in Nementcha region east of Constantine. Led by General Humbert, French army managed to break local resistance during difficult terrain campaign. Oued Sefioun engagement saw French exploit cavalry mobility to trap rebels in narrow gorge, inflicting heavy defeat.

In final phase of conquest of Ouarsenis massif, troops of General de Saint-Arnaud engaged decisive battle at Téniet el-Haad Pass. Battle, seeing coordinated commitment of elite units in very difficult mountain terrain, ended organized resistance in this zone. Tribes were caught off guard by rapid encirclement maneuver and disciplined frontal offensive.

The Battle of Zaatcha is one of most striking of late Algerian conquest. Oasis fortified by inhabitants and resisters from across region offered fierce resistance to French troops. Siege turned into pitched battle during final assault, where street fighting and ambushes in palm groves caused heavy losses. Capture of Zaatcha, at price of massacre, shocked opinion in metropolitan France.
