Question: Passage: In July 1449 Esen Tayisi  of the Mongols launched a large-scale, three-pronged invasion of China with his puppet khagan Toqtaq-Buqa. He personally advanced on Datong  in August. The eunuch official Wang Zhen, who dominated the Ming court, encouraged the 22-year-old Zhengtong Emperor to lead his own armies into battle against Esen. The size of Esen's army is unknown but a best guess puts it at some 20,000 men. The Ming army of about 500,000 was hastily assembled; its command was made up of 20 experienced generals and a large entourage of high-ranking civil officials, with Wang Zhen acting as field marshal. On August 3 Esen's army crushed a badly supplied Chinese army at Yanghe, just inside the Great Wall. The same day the Emperor appointed his half-brother Zhu Qiyu as regent. The next day he left Beijing for Juyong Pass. The objective was a short, sharp march west to Datong via the Xuanfu garrison, a campaign into the steppe and then a return to Beijing by a southerly route through Yuzhou. Initially the march was mired by heavy rain. At Juyong Pass the civil officials and generals wanted to halt and send the emperor back to Beijing, but their opinions were overruled by Wang Zhen. On August 16, the army came upon the corpse-strewn battlefield of Yanghe. When it reached Datong on August 18, reports from garrison commanders persuaded Wang Zhen that a campaign into the steppe would be too dangerous. The "expedition" was declared to have reached a victorious conclusion and on August 20 the army set out back toward China proper.

Question: Passage: He was however forced to fall back across the Danube, and the Ottomans in turn led a massive counter-offensive  which aimed to not only take back their recently captured possessions but also conquer Wallachia once and for all. The push was initially successful, managing to capture not only Giurgiu but also Bucharest and Târgovişte, in spite of meeting fierce opposition at Călugăreni . At this point the Ottoman command grew complacent and stopped pursuing the retreating Wallachian army, focusing instead on fortifying Târgovişte and Bucharest and considering their task all but done. Michael had to wait almost two months for aid from his allies to arrive, but when it did his counter-offensive took the Ottomans by surprise, managing to sweep through the Ottoman defences on three successive battlefields, at Târgovişte , Bucharest , and Giurgiu . The Battle of Giurgiu in particular was devastating for the Ottoman forces, which had to retreat across the Danube in disarray. The war between Wallachia and the Ottomans continued until late 1599, when Michael was unable to continue the war due to poor support from his allies. The turning point of the war was the Battle of Mezőkeresztes, which took place in the territory of Hungary on October 24-26, 1596. The combined Habsburg-Transylvanian force of 45-50,000 troops was defeated by the Ottoman army. The battle turned when Christian soldiers, thinking they had won the battle, stopped fighting in order to plunder the Ottoman camp. Despite this victory, the Ottomans realized for the first time the superiority of Western military equipment over Ottoman weapons. This battle was the first significant military encounter in Central-Europe between a large Christian army and the Ottoman Turkish Army after the Battle of Mohács. Nevertheless, Austrians recaptured Győr and Komarom in 1598.
Question: On which date did the Battle of Mezőkeresztes begin?

Answer: date
