Tavernay was lifted in a litter on to the back of a camel, and the remnant of the geographical expedition began its terrible homeward march. Eight hundred miles lay between Bir-el-Ghiramo and the safety of Ouargla. The Touaregs hung upon the rear of the force, but they did not attack again. They preferred another way. One evening a solitary Arab drove a laden camel into the bivouac. He was conducted to Stretton, and said, "The Touaregs ask pardon and pray for peace. They will molest you no more. Indeed, they will help you, and as an earnest of their true desire for your welfare they send you a camel-load of dates." Stretton accepted the present, and carried the message to Tavernay, who cried at once, "Let no one eat those dates." But two soldiers had already eaten of them, and died of poison before the morning. Short of food, short of sentinels, the broken force crept back across the stretches of soft sand, the greyish-green plains of halfa-grass, the ridges of red hill. One by one the injured succumbed; their wounds gangrened, they were tortured by the burning sun and the motion of the camels. A halt would be made, a camel made to kneel, and a rough grave dug. "Pelissier," cried Stretton, and a soldier stepped out from the ranks who had once conducted mass in the church of the Madeleine in Paris. Pelissier would recite such prayers as he remembered, and the force would move on again, leaving one more soldier's grave behind it in the desert to protest unnoticed against the economy of governments. Then came a morning when Stretton was summoned to Captain Tavernay's side. For two days Tavernay had tossed in a delirium. He now lay beneath a rough shelter of cloaks, in his right senses, but so weak that he could not lift a hand, and with a face so pinched and drawn that his years seemed to have been doubled. His eyes shone out from big black circles. Stretton knelt down beside him. "You have the letter?" "Yes." "Do not forget." He lay for a while in a sort of contentment, then he said--"Do not think this expedition has been waste. A small force first and disaster ... the big force afterwards to retrieve the disaster, and with it victory, and government and peace, and a new country won for France. That is the law of the Legion.... _My_ Legion." He smiled, and Stretton muttered a few insincere words. "You will recover, my captain. You will lead your companies again." "No," said Tavernay, in a whisper. "I do not want to. I am very happy. Yes, I say that, who joined the Legion twenty years ago. And the Legion, my friend, is the nation of the unhappy. For twenty years I have been a citizen of that nation.... I pity women who have no such nation to welcome them and find them work.... For us there is no need of pity."
