Cavalry! At this word whose mind does not involuntarily recall pictures of mailed knights rushing upon each other with levelled lances, and of the charging squadrons of Austerlitz, of Jena, of Marengo, of the Peninsula, and of Waterloo? Whose blood is not stirred with a throng of memories connected with the noble achievements of the war horse and his rider? Who does not imagine a panorama of all that is gay and glorious in warfare--prancing coursers, gilded trappings, burnished sabres, waving pennons, and glittering helmets--rank after rank of gallant riders--anon the blast of bugles, the drawing of sabres, the mighty rushing of a thousand steeds, the clash of steel, the shout, the victory? The chief romance of war attaches itself to the deeds accomplished by the assistance of the power and endurance of man's noblest servant. Every one has read so much poetry about valiant youths, mounted on fiery yet docile steeds, doing deeds of miraculous prowess in the ranks of their enemies--our literature is so full of tapestried representations of knightly retinues and charging squadrons--the towering form of Murat is so conspicuous in the narratives of the Napoleonic wars--and history has so often repeated the deeds of those horsemen who performed such illustrious feats in the combats of half a century ago, that we associate with the cavalry only ideas of splendor and glory, of wild freedom and dashing gallantry. But the cavalry service is far different from such vague and fanciful imaginations. Instead of ease, there is constant labor; instead of freedom, there is a difficult system of discipline and tactics; and instead of frequent opportunities for glorious charges, there is a constant routine of toilsome duty in scouting and picketing, with rarely an opportunity for assisting prominently in the decision of a great battle, or of winning renown in overthrowing the ranks of an enemy by the impetuous rush of a mass of horses against serried bayonets.
