Hope its alright to start an OT topic in chatter but the subject is interesting.
Charles Oman, "Art of War in the Middle Ages", was of the opinion that Hastings actually saw the beginning of the end for mass cavalry against formed infantry. By our Wars of the Roses the fully armoured knight mostly acted as heavy infantry. See battles of Poitier and Crecy for cavalry against infantry. What was important was for infantry to have effective missile weapons, without them, as at Adrianople, the infantry could get hemmed in and pressured into defeat. Then you must look at the ascendancy of the Swiss infantry who only suffered defeat because they neglected the missile arm and allowed their tactics to ossify.
