In January 1586, a Turkish privateer named
Mir Ali Beg sailed from
Mocha in
Yemen to the
Horn of Africa, intending to disrupt Portuguese shipping in the region. He began informing the Sultan that the naval forces of the Ottoman Empire in the Indian Ocean were unable to protect against Portuguese expansion. Consequently, Sultan
Murad III sent Mir Ali down with two other ships that were tasked with defending the
Swahili coast. Additionally, Mir Ali Beg convinced the inhabitants of
Mogadishu to join the fight against the Portuguese, and thus was joined by a few local vessels in support of his endeavors. The people of
Barawa and
Faza also declared their allegiance to the Ottoman Empire and, in the end, Mir Ali Beg had about 15 vessels. At
Pate, Mir Ali Beg captured a Portuguese merchant
carrack. At
Lamu, Mir Ali Beg captured a small galley belonging to Roque de Brito Falcão, while the king of Lamu delivered his city's Portuguese refugees to the Turks. Mir Ali Beg also established a fort at
Mombasa. Mir Ali Beg returned to Mocha with about 20 vessels and 100 Portuguese refugees, who were later ransomed. ==East African campaign, 1587==
