One could think so, but then about 150 years later the Hungarian chivalry (and pretty much the Hungarian kingdom itself) was annihilated by the same Ottomans at the battle of Mohacs, where there was no "high ground" involved. From the wiki page [1]:
> Hungary built up an expensive but obsolete army, structured similarly to that of King Francis I at the Battle of Pavia and mostly reliant on old fashioned heavily armoured knights on armoured horses (gendarme knights).
By that time the Ottomans had already started making heavy use of artillery (which is also one of the main reasons they had taken Constantinople back in 1453):
> The Ottoman army was a more modern force built around artillery and the elite, musket-armed Janissaries. The remainder consisted of feudal Timarli cavalry and conscripted levies from Rumelia and the Balkans
