The French, under Resident-General
Hubert Lyautey, launched the
Zaian War in the Middle Atlas in mid-1914 against the
Zaian Confederation of tribes. Early French gains were slowed by
Ou Hammou's victory at the
Battle of El Herri, support from the
Central Powers and greater co-operation between Ou Said, Ou Hammou and Amahouch. Ou Said's troops, numbering up to 5,000 tribesmen, engaged General
Noël Garnier-Duplessix' men at
Sidi Sliman, near to Kasbah Tadla, in May 1915 but were heavily defeated, losing 300 killed and 400 wounded in exchange for three French dead and five wounded. This victory was a major setback for Ou Said, leading to his withdrawal further into the mountains and a six-month period of relative peace. Further Berber resistance continued through the course of the
First World War, despite the death of Amhaouch in 1918, and the French found themselves still heavily opposed by the signing of the
Armistice with Germany in November 1918. The Zaian war was eventually brought to a close in 1921 following the death of Ou Hammou and the submission of the remaining Zaian Confederation members. However, Ou Said continued his resistance, fleeing first to the
Moulouya Valley and then to the highest mountains of the
High Atlas after his defeat at the Battle of
El Ksiba in April 1922 by General
Joseph-François Poeymirau and Colonel
Henry Freydenberg. He assigned the leadership of the Berber resistance to his son Bennacer and left to the
kasbah that he built in
Naour, where he remained until his death on 5 March 1924. Ou Said's followers continued their fight against the French until the final pacification of Morocco in 1934. ==See also==
