For some reason I do not recall Leadership being much of a focus in the melee events. Sure, the knights were sorted into two groups but, if I recall correctly, the fighting was largely chaotic and a chance for each knight to show off their combat prowess - not there ability to lead troops. I do not even think anyone below the rank of knight even participated. In the end each noble tried to capture as many other nobles as possible to later ransom. Again, focusing on individual combat and not on leading troops. I would love to hear from someone who has studied this in detail though. I very well may be way off.
