Câmpia Turzii (south of Cluj), effectively taking Transylvania under the Emperor's lead. Captain John Smith, the famous leader of the colony at Jamestown, Virginia and the Pocahontas story, was serving Sigismund Báthory as a mercenary. Smith was captured, and sold to Crimean Tatar slave traders. He later escaped to Poland before continuing on to England, from where he sailed to America in 1607. The Commonwealth was unable to capitalize on its gains, as the Polish–Swedish war had just started and the majority of Commonwealth forces were desperately needed to protect Livonia (Inflanty). A year later, Simion Movilă was ousted from the Wallachian throne by local boyars who replaced him with Radu Șerban, with the consent of the Ottomans (relieved to see the Polish influence at the Danube diminish). The Commonwealth managed to retain control over Moldavia, and the only side not to gain anything was the Habsburgs: in fact, they lost control over all of their former possessions in the region. However, the Peace of Žitava ended the Habsburg-Ottoman conflict known as the Long War, and forced the Ottomans to recognize the Habsburgs as equals, due to the former's inability to penetrate royal Hungary. This ended direct war between the Ottomans and the Habsburgs for decades, but the two powers still struggled for influence in the region that constitutes modern-day Romania. 1607–1613 Ieremia Movilă died in 1606. In 1607 Stefan Potocki set his brother-in-law (and son of Ieremia), Constantin Movilă (Konstanty Mohyła), on the Moldavian throne. However, Stefan Potocki was one of the pro-Habsburg magnates and Gabriel Báthory, the anti-Habsburg ruler of Transylvania, removed Constantin Movilă in 1611. The Moldavian throne now fell to Ștefan II Tomșa (Tomża). A second intervention by Stefan Potocki (with tacit assistance from Sigismund III, but against the will of Sejm and Senate) in 1612 was a complete failure. Potocki's 7,000 strong army was defeated on 19 July in the Battle of Sasowy Róg (near Ștefănești) by troops of Tomșa and Khan Temir's Tatars of the Budjak Horde. Stefan Potocki and Constantin Movilă ended their lives in Ottoman captivity in Constantinople. A counter-raid of Tatars and Tomșa on the Commonwealth was stopped by Żółkiewski without a fight, and an agreement between Żółkiewski and Tomșa was signed in October 1612 (at Khotyn). Tomșa assured about his friendliness, that he will help to patch up conflict between the Ottoman Empire and the Commonwealth and pledged allegiance to
