Battle of Annual
In 1910, the Spaniards restarted the mines and undertook harbor works at Mar Chica, but hostilities broke out again in 1911. On 22 July 1921, the Berbers under the leadership of Abd el Krim inflicted a grave defeat on the Spanish at the Battle of Annual. The Spanish retreated to Melilla, leaving most of the protectorate under the control of the Republic of Rif.
