阿尤恩
On 12 January, a division of the Saharan Liberation Army attacked the Spanish garrison at El Aaiún. Beaten back and forced into retreat by the Spaniards, the army turned its efforts to the southeast. Another opportunity presented itself the next day at Edchera, where two companies of the 13th Legionnaire battalion were conducting a reconnaissance mission. Slipping unseen into the large dunes near the Spanish positions, the Moroccans opened fire.
