At the same time a counter-revolution in the balance. [contrarian]
At the same time a counter-revolution in the balance of warfare was afoot. The mailed cavalry which from the fifth century had eclipsed the ordered ranks of the legion were wearing out their long day. A new type of infantry raised from the common people began to prove its dominating quality. This infantry operated, not by club or sword or spear, or even by hand-flung missiles, but by an archery which, after a long development, concealed from Europe, was very soon to make an astonishing entrance upon the military scene and gain a dramatic ascendancy upon the battlefields of the Continent.
