“‘Perhaps, indeed, that is so.’

“And I, who had seen some very terrible things in my time, began to cry.  And I felt, in the presence of this corpse, on that icy cold night, in the midst of that gloomy plain; at the sight of this mystery, at the sight of this murdered stranger, the meaning of that word ‘horror.’

“I had the same sensation last year, while interrogating one of the survivors of the Flatters Mission, an Algerian sharpshooter.

“You know the details of that atrocious drama.  It is possible, however, that you are unacquainted with one of them.

“The colonel travelled through the desert into the Soudan, and passed through the immense territory of the Touaregs, who, in that great ocean of sand which stretches from the Atlantic to Egypt and from the Soudan to Algeria, are a kind of pirates, resembling those who ravaged the seas in former days.

“The guides who accompanied the column belonged to the tribe of the Chambaa, of Ouargla.

“Now, one day we encamped in the middle of the desert, and the Arabs declared that, as the spring was still some distance away, they would go with all their camels to look for water.

“One man alone warned the colonel that he had been betrayed.  Flatters did not believe this, and accompanied the convoy with the engineers, the doctors, and nearly all his officers.

“They were massacred round the spring, and all the camels were captured.

“The captain of the Arab Intelligence Department at Ouargla, who had remained in the camp, took command of the survivors, spahis and sharpshooters, and they began to retreat, leaving behind them the baggage and provisions, for want of camels to carry them.

“Then they started on their journey through this solitude without shade and boundless, beneath the devouring sun, which burned them from morning till night.

“One tribe came to tender its submission and brought dates as a tribute.  The dates were poisoned.  Nearly all the Frenchmen died, and, among them, the last officer.

“There now only remained a few spahis with their quartermaster, Pobeguin, and some native sharpshooters of the Chambaa tribe.  They had still two camels left.  They disappeared one night, along with two, Arabs.

“Then the survivors understood that they would be obliged to eat each other, and as soon as they discovered the flight of the two men with the two camels, those who remained separated, and proceeded to march, one by one, through the soft sand, under the glare of a scorching sun, at a distance of more than a gunshot from each other.

“So they went on all day, and when they reached a spring each of them came to drink at it in turn, as soon as each solitary marcher had moved forward the number of yards arranged upon.  And thus they continued marching the whole day, raising everywhere they passed, in that level, burnt up expanse, those little columns of dust which, from a distance, indicate those who are trudging through the desert.
