At Hattin after the Crusaders had retreated to their hilltop last stand positions the knights tried to break through the Muslim lines (either to flee, or to get at Saladin). At least three times. Downhill. And were repulsed every time.
"Arab" cavalry (among whom were many Turkish, Kurdish and Armenian mercenaries) of the period was typically relatively heavy compared to the typical light horse-archer of the Turkic nomads. They typically had composite bows too - although used them in the so-called "Persian" doctrine - but were better mounted on larger and stronger warhorses, and had considerably more armour.
