Moldavian Campaign (1538)

The Sultan marched with an army of 240,000 men, including Crimean Tatars.^[4] Suleiman sent his ambassador, Sinan Çavush, to Moldavia, calling Petru to surrender and come to Istanbul. But, nine days later, he reported to Suleiman that Petru refused the offer. Petru had an army of 70,000 men, including 30,000 Moldavians and 40,000 Hungarian men from John Zápolya. Petru, in the mountainous and rocky areas of Moldavia, launched hit-and-run attacks against the Ottoman soldiers, but his forces proved insufficient to resist the Ottomans.^[5][6] Without confronting the Ottoman Army directly, he fled to Transylvania.^[7]

The Sultan appointed Mehmed Pasha as commander-in-chief, had a great bridge built over the Danube River, and crossed to the opposite bank. With the Rumelian, Anatolian, and akıncı troops, he entered Moldavia. He reached the banks of the Prut River with his army and crossed it by building a bridge. The Crimean Khan Sahib Giray rendezvoused with Suleiman.^[8] The combined armies marched towards Suceava and began besieging the city on September 16. Large iron cannons were cast in front of the fortress. Realizing they could not defend the fortress against the Ottomans, the Moldavians surrendered on the same day and handed over the fortress's keys to the Sultan. The treasures and goods hidden in the fortress fell into the hands of the Ottoman soldiers.^{[9][10][11][12]} The conquest of Suceava was attended by Rüstem Pasha, Lütfi Pasha, and Mehmed Pasha.^[13]

After this conquest, the lords and voivodes of the Moldavia region came to Suleiman's imperial tent and submitted. One of their own was appointed voivode by the Sultan, whose name was Stephan Locust.^[14] During the campaign, the Ottomans annexed Southern Bessarabia, the coast of the Northern Black Sea, and Tighina.^[15] The Ottomans concluded the campaign in October of the same year.^[16]
