The Somali-Ottoman offensive managed to drive out the Portuguese from several important cities such as Pate, Mombasa and Kilwa. However, the Portuguese governor sent envoys to Portuguese India requesting a large Portuguese fleet. This request was answered and it reversed the previous offensive of the Muslims into one of defense. The Portuguese armada managed to re-take most of the lost cities and began punishing their leaders, but they refrained from attacking Mogadishu, securing the city's autonomy in the Indian Ocean. The Ottoman Empire would remain an economic partner of the Somalis. Throughout the 16th and 17th centuries successive Somali Sultans defied the Portuguese economic monopoly in the Indian Ocean by employing a new coinage which followed the Ottoman pattern, thus proclaiming an attitude of economic independence in regard to the Portuguese.
