 Sinan Pasha and Turgut Reis collaborated on several naval expeditions in the Mediterranean Sea, particularly on the coasts of Italy and North Africa.Sinan was not an expert on naval issues as much as Turgut Reis, who was a more popular commander among the admirals and captains of the navy, and this often caused conflict between the two.In an incident following the Ottoman conquest of Tripoli in 1551, the entire Ottoman fleet left Sinan Pasha on the shore and followed Turgut Reis into the Tyrrhenian Sea, declaring that they would accept only Turgut as their commander.
