On the eastern front of the war, Michael the Brave, prince of Wallachia, started a campaign against the Ottomans in the autumn of 1594, conquering several castles near the Lower Danube, including Giurgiu, Brăila, Hârşova, and Silistra, while his Moldavian allies defeated the Ottoman armies in Iaşi and other parts of Moldova. Michael continued his attacks deep within the Ottoman Empire, taking the forts of Nicopolis, Ribnic, and Chilia, and even reaching as far as Adrianople. At one point his forces were only from the Ottoman capital, Constantinople.
