Roudon is an experienced cavalryman. For ten years he knew the mad, intoxicating dashes with the Algerian contingents in Morocco, the mysterious attractions of reconnaissances in the long reaches of the valleys of the Sahara, impetuous charges and wild triumphant pursuits among the red Spahis with their Damascus swords, amid the glistening sands which rise toward the sun in golden spangles. At the beginning of the war he was thrown into a regiment of metropolitan cavalry and fought in Lorraine and Belgium. He lived through the horrible hours of retreat, assuming the perilous mission of rearguard while the other regiments withdrew in good order. He fought on foot, in the edges of woods, to stop to the last moment the march of the enemy while the rear went on to the Marne. He endured those long, seemingly endless, waits on foot in front of his horse, the bridle on his arm, saber in scabbard, under the storm of shells and the invisible menace of bullets. There were no trenches then. Roudon is a cavalryman in his soul and his love for the service. So, attached to an improvised service which is neither cavalry, artillery, nor infantry, he does not know what to make of it, and he rages at it through his excess of conscience and too exclusive love of duty perfectly done. The echelon of the third company arrives on the Place in good order a few seconds after us. Hémin leads it and he marches on foot beside his column, hands in his pockets, whistling. Hémin is a type, and not the least interesting among the complex personalities of our command, for we are cavalrymen transformed into infantry, but we’re still cavalrymen just the same. Hémin is as much a cavalryman by trade as Roudon, and perhaps even more so. He was successively a stable boy in a racing stable at Chantilly, then a jockey, and finally a trainer, after he had done his military service in a regiment of chasseurs. So he is a horseman par excellence. But he never made war as a cavalryman before. Since the beginning of the war he has been attached to various services. First, he was an infantry scout, a standard bearer for a general, a courier for a major, and he was transferred to the companies of machine guns when they were definitely established. Hémin has a style all his own. To all appearances he is neither a cavalryman nor a foot soldier. His jacket is a Colonial one with anchors and cuff-facings, but it has white stripes. He wears great yellow boots, a cavalryman’s spurs, his breeches are reinforced with olive leather, and his head is covered with a very small black cap. Another curious characteristic is that Hémin, the excellent horseman, always walks when he accompanies his detachment. * * * * * When we are assembled, we turn the command of the detachment over to Roudon, the senior officer, and he leads the way. Hémin and I bring up the rear some distance back.
