Excepting a dash in Champagne, not since trench warfare began had the cavalry had any chance. The thought of action was an hypothesis developed from memory of charges in the past. Aeroplanes took the cavalry's place as scouts, machine guns and rifles emplaced behind a first-line trench which had succumbed to an attack took its place as rearguard, and aeroplane patrols its place as screen. Yet any army, be it British, French, or German, which expected to carry through an offensive would not turn all its cavalry into infantry. This was parting with one of the old three branches of horse, foot and gun and closing the door to a possible opportunity. If the Japanese had had cavalry ready at the critical moment after Mukden, its mobility would have hampered the Russian retreat, if not turned it into a rout. When you need cavalry you need it "badly," as the cowboy said about his six-shooter. Should the German line ever be broken and all that earth-tied, enormous, complicated organization, with guns emplaced and its array of congested ammunition dumps and supply depots, try to move on sudden demand, what added confusion ten thousand cavalry would bring! What rich prizes would await it as it galloped through the breach and in units, separating each to its objective according to evolutions suited to the new conditions, dismounted machine guns to cover roads and from chosen points sweep their bullets into wholesale targets! The prospect of those few wild hours, when any price in casualties might be paid for results, was the inspiration of dreams when hoofs stamped in camps at night or bits champed as lances glistened in line above khaki-colored steel helmets on morning parade. A taste, just a taste, of action the cavalry was to have, owing to the success of the attack of July 14th, which manifestly took the Germans by surprise between High and Delville Woods and left them staggering with second-line trenches lost and confusion ensuing, while guns and scattered battalions were being hurried up by train in an indiscriminate haste wholly out of keeping with German methods of prevision and precision. The breach was narrow, the field of action for horses limited; but word came back that over the plateau which looked away to Bapaume between Delville and High Woods there were few shell-craters and no German trenches or many Germans in sight as day dawned.
