Everywhere cavalry came trampling and crowding out of the woods and cantering away toward the north, hussars mostly, at first, then chasseurs-à-cheval, an entire brigade of these splendid lancers, pouring out into the road and taking the Ausone route at a gallop.

More motor cycles flashed past; then half a dozen automobiles, in which officers were seated examining maps; then up the road galloped dragoon lancers, wearing grey helmet slips and escorting three light field guns, the drivers of which were also dragoons—a sight Warner had never before seen.

An officer, wearing a plum-colored band of velvet around his red cap, and escorted by a lancer, came from the direction of Ausone, leaned from his saddle, and shook the ambulance chauffeur awake.

"Drive back toward Saïs," he said. "They are taking care of our people across the river, and you may be needed below!" He saluted the Sisters of Charity: "A biplane has fallen by the third pontoon. You may be needed there," he explained.

Sister Eila rose; her face was ashen.

"What biplane, Major?" she asked unsteadily.

"I don't know. British, I think. It came down under their shrapnel like a bird with a broken wing."

He rode on. Warner aided the Sisters of Charity to their seats. Then he and Asticot jumped aboard.

As they turned slowly, two wheels describing a circle through the dusty grass of the ditch, half a dozen mounted gendarmes trotted out of the woods with sabers drawn.

Behind them came four mounted hussars. A man walked in the midst of them. There was a rope around his neck, the end of which was attached to the saddle of one of the troopers.
