The first clash between the Ottomans and Portuguese came in 1538, when the beylerbey of Egypt, Süleyman Pasha, was given 74 ships with 3000 men and big guns and charged with taking Portugal-held Diu in India.[4] This first attack failed, but Ottoman forces under Süleyman Pasha were able to win a decisive victory at Aden later that year in the largest naval attempt by the Ottomans in the war.[5] Aden, located in Yemen on the Indian Ocean, was and still is a major port in the region for transshipment of goods destined for the Levant and the Red Sea; the Ottoman capture was a major blow to the Portuguese blockade. Later attacks by both the Ottomans and Portuguese failed to achieve any advantage; not until 1552 were the Ottomans able to launch a second large campaign, when they attempted to seize Hormuz with 25 galleys, 4 galleons, and 850 men, but were ultimately defeated.[6]
