Battle of Beni Bou Yahi

On 7 September 1923, French forces attacked the heights of Beni Bou Yahi, a strategic tribal zone linking the eastern Rif to the Alhucemas massif. The offensive aimed to disorganise Abdelkrim's logistical rear before a major operation planned for the following year. Fighting was violent, with fierce Rifian resistance in relief extremely favourable to defenders. French firepower, notably artillery and aerial bombardment, finally forced Rifian fighters to abandon their positions.

After partial successes in 1922–1923 in the south and west of the Rif, the French planned a methodical reconquest of rebel territory. The fortified village of Beni Bou Yahi was a natural lock at the heart of the Rifian dispositions. Its capture would open the way to reconquest of the Ajdir region and the Alhucemas massif. It was also a psychological operation intended to weaken Abdelkrim's local prestige among tribes still hesitating to support him fully. The battle thus marks a transition toward a more structured war.

The attack began with heavy artillery fire and targeted air raids on ridges and fortified villages. Ground troops advanced in successive assault lines, protected by machine-gun sections and mortars. Moroccan goumiers were used for outflanking and flank manoeuvres, while legionnaires drove into the centre of enemy positions. The Rifians attempted a counter-attack late in the afternoon on the left flank, but it was broken by a rapid reaction from the alpine chasseurs.

The victory at Beni Bou Yahi enabled France to gain a foothold in a zone hitherto inviolable by colonial forces. It cut a crucial supply line for the Rifians and disorganised several tribes loyal to Abdelkrim. This success reinforced coordination between French command in Morocco and the Spanish, who on their side were preparing the Alhucemas landing. Politically, it confirmed France's irreversible commitment to a large-scale colonial war, which would soon mobilise more than 100,000 men.
