On 11 September, the Ottoman army began to ford the river Tisza near Zenta, unaware that the Imperial Army was nearby. Captain Jovan Popović Tekelija, commander of the Serbian Militia, who was monitoring the advances of the Ottomans, immediately informed Prince Eugene, a captured Ottoman pasha was forced to confirm the information. Tekelija then led the Imperial army over swamps and bog to the rear of the Turks encampment. Two hours before sunset, the arrival of the Habsburg army's Imperial army forced march to Zenta shocked the Ottoman forces as they were still in the process of crossing the river and did not think that the Christian army could get there so quickly. Sultan Mustafa, his baggage, and the artillery were on the Temeşvar bank while most of the infantry was still with the Grand Vizier on the other bank.
