[1] The rebels of the Mokrani Revolt, after several successes, headed for Algiers via Alma (Boudouaou) after having taken control of Palestro (Lakhdaria), Laazib Zamoum (Naciria), Bordj Menaïel, the Issers and the Col des Beni Aïcha (Thenia).

[4] The Algerian rebels then made a fatal error in their advance towards Algiers, by igniting a fire in the woods around Reghaïa which alerted the French garrison.

[5] The Governor General of Algiers, Louis Henri de Gueydon, decided to retake the colony of Alma by sending on April 21, 1871, an expeditionary unit tasked with stopping the march of the Algerian masses who were threatening the Mitidja.

[6] The unit consisted of 2,300 infantrymen made up of Zouaves, Algerian riflemen, militiamen from Algiers, mobiles from Hérault, over 200 Chasseurs d'Afrique, a few spahis and 4 mounted howitzers.

[8] It was Colonel Alexandre Fourchault who took charge of the counter-attack of the Troupes coloniales, to push back the Algerians who were going to overtake Boudouaou to begin the conquest of Mitidja.
