But the traces grew fresher and fresher: here a horse had been abandoned; a little farther, a jackass. 'We have got the rascals!' said the soldiers, and their strength revived. At last, towards eleven o'clock, whilst the column was passing through a deep ravine, a thick smoke was seen behind a hill. This time the enemy was assuredly there. Fatigue vanished as by enchantment. In an instant cloaks were rolled, priming renewed, horses girthed up; all was ready, and the troops formed for the attack. Three hundred infantry supported three columns of cavalry; the centre was commanded by Colonel Tartas of the 4th Chasseurs. The advance began; just then there was the report of a musket; it was a vedette whom our scouts had been unable to surprise. The Arab galloped up the hill, waving his _burnous_. At the same moment, the drums of the regulars beat to arms; there was a stir in our ranks. The cavalry broke into a trot; the infantry, forgetting forced marches, followed at a run, and from the top of the hill we saw the two battalions of regulars, who had been unable to reach the opposite summit, halt half way up. Away went the cavalry, sabre in hand, horses at a gallop, Colonel Tartas at their head. They were met by a volley of musketry; some fell, but the avalanche broke through the obstacle, and the Arabs were cut down on all sides. Their horsemen try to escape--some flying to the left, others straight forward. They are pursued by all whose horses are not yet knocked up; and the Caïd Osman rolls over with his charger, which is hit in the head. M. de Caulaincourt, admirably mounted, continues the race; he kills one of the Emir's horsemen; but, separated by a ridge of ground from his soldiers, whom he has outstripped, he is surrounded by enemies. Without losing his presence of mind, he spurred his horse and broke through the circle, sabre in hand; when, just as he was about to rejoin his men, an Arab, issuing from a glade, shot him with a pistol, close to the eye. The horse galloped on, and carried back the wounded officer to his troop. The blood streamed, the flesh hung in shreds; M. do Caulaincourt, however, was still conscious. Lifted from his horse, a soldier took him on his back and carried him to the surgeon, traversing the scene of the combat, a true field of the dead. In a narrow space lay five hundred corpses, nearly all frightfully mutilated by the sabres of our chasseurs.
