And in a few moments he fell asleep, and, two hours later, sleeping, died. A pile of stones was built above his grave, and the force marched on. Gaunt, starved, and ragged, the men marched northwards, leaving the Touat country upon their left hand. It struck the caravan route from Tidikelt to Ouargla; it stumbled at last through the gates of the town. Silently it marched through the streets to the French fortress. On no survivor's face was there any sign of joy that at last their hardships were over, their safety assured. All were too tired, too dispirited. The very people who crowded to see them pass seemed part of an uninteresting show. Stretton went at once to the Commandant and told the story of their disaster. Then he handed him the letter of Captain Tavernay. The Commandant broke the seal and read it through. He looked up at Stretton, a thin spent figure of a man overwrought with sleeplessness and anxiety.

"Tell me how and when this was written," said the Commandant.

Stretton obeyed, and after he had heard, the Commandant sat with his hand shading his eyes. When he spoke, his voice showed that he was deeply moved.

"You know what the letter contains, Sergeant Ohlsen?"

"No, my Commandant."

"Read, then, for yourself;" and he passed the letter across his office table. Stretton took it and read. There were a few lines written--only a few; but those few lines recommended Sergeant Ohlsen for promotion to the rank of officer. The Commandant held out his hand.

"That is like our Tavernay," he said. "He thought always of his soldiers. He wrote it at once, you see, after the battle was over, lest he should die and justice not be done. Have no fear, my friend. It is you who have brought back to Ouargla the survivors of the Legion. But you must give your real name. There is a scrutiny before a soldier is promoted to the rank of office. Sergeant Ohlsen. That is all very well. But Lieutenant----. Come, Lieutenant who?"

He took up his pen.

"Lieutenant Sir Anthony Stretton," replied Tony; and the Commandant wrote down the name.
