In 1548 he was appointed
Beylerbeyi (
Chief Governor) of
Algeria by Suleiman the Magnificent. In that same year he ordered the construction of a quadrireme galley at the naval arsenal of
Djerba, which he started using in 1549. In August 1548 he landed at
Castellamare di Stabia on the Bay of Naples and captured the city along with nearby
Pozzuoli. From there he went to
Procida. A few days later, he captured a Spanish galley loaded with troops and gold at
Capo Miseno near
Procida. In the same days he captured the Maltese galley,
La Caterinetta, at the Gulf of Naples, with its cargo of 70,000 gold ducats which were collected by the Knights of St. John from the churches of France with the aim of strengthening the defenses of
Tripoli, which was then under Maltese control. In May 1549 he set sail towards Liguria with 21 galleys and in July he assaulted
Rapallo, later replenishing his ships with water and other supplies at
San Fruttuoso. From there he sailed to
Portofino and landed at the port, before appearing at
San Remo where he captured an
Aragonese galley from
Barcelona ] heading towards Naples. From there he first sailed towards Corsica and later towards Calabria<, where he assaulted the city of
Palmi. In February 1550, sailing with a force of 36 galleys, he recaptured Mahdia along with
Al Munastir,
Sousse and most of
Tunisia. In May 1550 he assaulted the ports of
Sardinia and Spain and landed on their coasts with a force of six galleys and 14 galiots. Still in May he unsuccessfully tried to capture Bonifacio in Corsica. On his way back to Tunisia, he stopped at Gozo to replenish his ships with water and to gather information on the activities of the Maltese Knights. He later sailed towards Liguria. In June 1550, while Turgut Reis was sailing near Genoa, Andrea Doria and Bailiff
Claude de la Sengle of the Maltese Knights attacked Mahdia in Tunisia. In the meantime, Turgut Reis was busy assaulting and sacking Rapallo for a third time, before raiding the coasts of Spain. He then sailed to the
Tyrrhenian Sea and towards the beginning of July landed at the western shores of Sardinia, before returning to Djerba, where he learned that Doria and Claude de la Sengle had been attacking Mahdia and
Tunis. He collected a force of 4500 troops and 60
sipahis and marched on Mahdia to assist the local resistance. He did not succeed and returned to Djerba with his troops. In September 1550 Mahdia surrendered to the joint Spanish-Sicilian-Maltese force. In the meantime, Turgut Reis was repairing his ships at the beach of Djerba. On October, Andrea Doria appeared with his fleet at Djerba and blocked the entrance of the island's lagoon with his ships, trapping the beached galleys of Turgut Reis inside the Channel of Cantera. Turgut Reis had all his ships dragged overland through hastily dug canals and on a heavily greased broadway to the other side of the island and sailed to
Istanbul, capturing two galleys on the way, one Genoese and one Sicilian, which were en route to Djerba in order to assist the forces of Doria. Prince Abu Beker, son of the Sultan of Tunis, who was an ally of Spain, was on the Genoese galley. by
Eugenio Caxes. After arriving in Istanbul, Turgut Reis, under mandate by
Sultan Suleiman, mobilized a fleet of 112
galleys and two
galleasses with 12,000
Janissaries, and in 1551 set sail with the Ottoman admiral
Sinan Pasha towards the
Adriatic Sea and bombarded the Venetian ports, inflicting serious damage on Venetian shipping. In May 1551 they landed on Sicily and bombarded the eastern shores of the island, most notably the city of
Augusta, as revenge for the Viceroy of Sicily's role in the invasion and destruction of Mahdia, where most inhabitants had been massacred by the joint Spanish-Sicilian-Maltese force. They then attempted to capture Malta, landing with about 10,000 men at the southern port of
Marsa Muscietto. They laid siege to the citadels of
Birgu and
Senglea, and later went north and assaulted
Mdina, but lifted the siege after realizing that it was impossible to capture the island with the number of troops in hand. Instead, they moved to the neighboring island of
Gozo, where they bombarded the citadel for several days. The Knights' governor there, Galatian de Sesse, realizing that resistance was futile, surrendered the citadel, and the corsairs sacked the town. Taking virtually the entire population of Gozo (approximately 5,000 people) into captivity, Turgut and Sinan set sail from the port of Mġarr ix-Xini in Gozo and headed towards Libya, where they shipped the captives to
Tarhuna Wa Msalata. They later sailed towards Tripoli with the aim of conquering the strategic port city and its environs. == Sanjak Bey of Tripoli ==
