Despite the success of the previous year, the situation for the Ottomans worsened yet again in 1595. A Christian coalition of the former vassal states along with Austrian troops recaptured Esztergom and marched southward down the Danube. Michael the Brave, the prince of Wallachia started a campaign against the Turks (1594–1595), conquering several castles near the Lower Danube, including Giurgiu, Brăila, Hârşova, and Silistra, while his Moldavian allies defeated the Turks in Iaşi and other parts of Moldavia. Michael continued his attacks deep within the Ottoman Empire, taking the forts of Nicopolis, Ribnic, and Chilia and even reaching as far as Adrianople (Edirne), the former Ottoman capital city; no Christian army had set foot in the region since the days of the Byzantine Empire under the Palaiologoi.
