In 1716, Grand Vizier Damat Ali gathered a 160,000[citation needed] strong Ottoman army at Belgrade, at the core of which were 40,000 Janissaries, 20,000 Sipahi, and 10,000 Tatars, together with some renegade Kuruc cavalry. They crossed the Sava at Zemun at the end of July, and moved on the right bank of the Danube towards Sremski Karlovci (in the Habsburg territory). The Tatars, with Moldavians and Kurucs drove into Transylvania, but the Transylvanian forces were no match for the Tatars.
