the Ottomans to take the island began in 1431 when Ottoman troops under Ali Bey landed on the island. The Ottomans tried to take the city castle and raided the surrounding area, but were repulsed. The Siege of Corfu (1537) was the first great siege by the Ottomans. It began on 29 August 1537, with 25,000 soldiers from the Ottoman fleet landing and pillaging the island and taking 20,000 hostages as slaves. Despite the destruction wrought on the countryside, the city castle held out in spite of repeated attempts over twelve days to take it, and the Turks left the island unsuccessfully because of poor logistics and an epidemic that decimated their ranks. Thirty-four years later, in August 1571, Ottoman forces returned for yet another attempt to conquer the island. Having seized Parga and Mourtos from the Greek mainland side, they attacked the Paxi islands. Subsequently they landed on Corfu's southeast shore and established a large beachhead all the way from the southern tip of the island at Lefkimi to Ipsos in Corfu's eastern midsection. These areas were thoroughly pillaged as in past encounters. Nevertheless the city castle stood firm again, a testament to Corfiot-Venetian steadfastness as well as the Venetian castle-building engineering skills. Another castle, Angelokastro, situated on the northwest coast near Palaiokastritsa (Greek: Παλαιοκαστρίτσα meaning Old Castle place) and located on particularly steep and rocky terrain, also held out. The castle is a tourist attraction today. These defeats in the east and the west of the island proved decisive, and the Ottomans abandoned their siege and departed. Two years later they repeated their attempt. Coming from Africa after a victorious campaign, they landed in Corfu and wreaked havoc on rural areas. Following a counterattack by the Venetian-Corfiot forces, the Ottoman troops were forced to leave the city sailing away. The second great siege of Corfu took place in 1716, during the last Ottoman–Venetian War (1714–18). After the conquest of the Peloponnese in 1715, the Ottoman fleet appeared in Buthrotum opposite Corfu. On 8 July the Ottoman fleet, carrying 33,000 men, sailed to Corfu from Buthrotum and established a beachhead at Ipsos. The same day, the Venetian fleet encountered the Ottoman fleet off the Corfu Channel and defeated it in the ensuing naval battle. On 19 July, after taking a few outlying forts, the Ottoman army reached the hills around the city of Corfu and laid siege to it.
