The French knights thus continued up the hill, though accounts state that more than half were on foot by this point, either because they had been unhorsed by the lines of sharpened stakes or had dismounted to pull up stakes. Struggling in their heavy armor, they reached the plateau on the top of the slope, where they had expected to find fleeing Turkish forces, but instead found themselves facing a fresh corps of sipahis, whom Bayezid had kept in reserve. As the sipahis surged forward in the counterattack sounding trumpets, banging kettle drums and yelling "God is greater!", the desperation of their situation was readily apparent to the French and some knights broke and fled back down the slope.
