Such was the new infantry of Europe at the close of the fifteenth and the opening of the sixteenth centuries, not yet perfected, but advancing rapidly to an efficiency and importance such as had for many centuries been unknown in Europe. And now the nations poured down into the fair land of Italy to teach each other in that second birthplace of all arts the new-born art of war. France was the first that came; and few armies have caused greater wonder in Europe than that which marched with Charles the Eighth through Florence in 1496. The work begun for the expulsion of the English from France had been steadily continued. Louis the Eleventh had hired Swiss sergeants to drill his infantry, and Picardie, the senior regiment of the old French line, was already in potential existence. But it was not these, but other men who set the Florentines at gaze. For there were to be seen the Scottish archers, the finest body-guard alike for valour and for stature in the world, the Swiss, marching by with stately step and incredible good order, the chivalrous gentlemen of France, mailed from top to toe and gorgeous in silken tabards, riding in all the pride of Agincourt avenged, mounted archers less heavy but more workmanlike as befitted light cavalry, and lastly a great train of brass artillery, cannons and culverins, and falcons, the largest weighing six thousand pounds and mounted on four wheels, the smallest made for shot no bigger than a doctor's pills and travelling on two wheels only. Already the quick-witted French had thought out the principle of the limber, and had made two wheels of their heavy guns removable. Already too they had trained the drivers of the lighter ordnance to move as swiftly as light cavalry.[63]
