It had been found expedient to send a few militia regiments to the front in May, and these regiments, together with what still remained of our regular army, made a brave stand against the Japanese outposts in the mountains. Insufficiently trained and poorly fed as they were, they nevertheless accomplished some excellent work under the guidance of efficient officers; but the continual engagements with the enemy soon thinned their ranks. These regiments got to know what it means to face a brave, trained enemy of over half a million soldiers with a small force of fifty thousand; they learned what it means to be always in the minority on the field of battle, and thus constant experience on the battle-field soon transformed these men into splendid soldiers. Especially the rough-riders from the prairies and the mountains, from which the cavalry regiments were largely recruited, and the exceedingly useful Indian and half-breed scouts, to whom all the tricks of earlier days seemed to return instinctively, kept the Japanese outposts busy. Their machine-guns, which were conveyed from place to place on the backs of horses, proved a very handy weapon. But their numbers were few, and although this sort of skirmishing might tire the enemy, it could not effectually break up his strong positions. Ever on the track of the enemy, surprising their sentries and bivouacs, rushing upon the unsuspecting Japs like a whirlwind and then pursuing them across scorching plains and through the dark, rocky defiles of the Rockies, always avoiding large detachments and attacking their commissariat and ammunition columns from the rear, popping up here, there and everywhere on their indefatigable horses and disappearing with the speed of lightning, this is how those weather-beaten rough-riders in their torn uniforms kept up the war and stood faithful guard! Brave fellows they were, ever ready to push on vigorously, even when the blood from their torn feet dyed the rocks a deep red! No matter how weary they were, the sound of the bugle never failed to endow their limbs with renewed energy, and they could be depended on to the last man to do whatever was required of them. It was on these endless marches, these reckless rides through rocky wastes and silent forests--to the accompaniment of the tramp of horses, the creaking of saddles and the rush and roar of rolling stones on lonely mountain-trails--that those strange, weird rhythms and melodies arose, which lived on long afterwards in the minds and hearts of the people.
