 Over the next several decades Somali-Portuguese tensions would remain high and the increased contact between Somali sailors and Ottoman corsairs worried the Portuguese who sent a punitive expedition against Mogadishu under João de Sepúvelda but was soundly defeated by the Ajuran naval forces before they even had a chance to reach the Ajuran capital city and João de Sepúvelda was eventually killed in the Battle of Benadir and all his ships were blown up into smithereens.Ottoman-Somali cooperation against the Portuguese in the Indian Ocean reached a high point in the 1580s when Ajuran clients of the Somali coastal cities began to sympathize with the Arabs and Swahilis under Portuguese rule and sent an envoy to the Turkish corsair Mir Ali Bey for a joint expedition against the Portuguese.He agreed and was joined by a large Somali fleet, which began attacking Portuguese colonies in Southeast Africa.
