As they reached the plateau above the school and halted for a few moments to look back across the valley of the Récollette, Warner began to understand.
The cannonading in the north had ceased. On every road, in whichever direction he looked, troops, artillery, and wagons were moving eastward. This was no mere cavalry reconnoissance; it was a serious offensive movement in force toward the east. Eastward and south lay the Vosges; beyond, the lost provinces stretched away in green valleys toward the Rhine.
There lay the objective of this movement which was based on the great Barrier Forts from Verdun to Toul, from Toul to Nancy and Luneville, southward to Epinal, to the great, grim citadel of Belfort.
This was no raid, no feint, no diversion made by a flying corps along the frontier. A great screen of cavalry was brushing back every hostile scout toward the mountains; the contact at the cement works was a mere detail. Nor was this movement directed toward the north, where the Grand Duchy was crawling alive with Prussians already battering at the "Iron Gate of France."
No, the guns of Longwy were not calling these French horsemen north, whatever was happening at Verdun or along the Moselle. Their helmets were moving toward the east, toward the passes of the Vosges where Alsace lay, and Lorraine. Metz, Strassburg, Colmar, Mülhausen, beckoned from every tall tower, every gable, every spire. It was invasion! Armed France was riding toward the rising sun.
Sister Eila's pale, intelligent face was lifted to the distant horizon; her clear, exalted gaze made it plain to him that she, also, had begun to understand.
As for Asticot, he was finishing the core of his apple and watching details in the vast panorama out of his tiny mouse-eyes; and whether he understood or cared to understand no man might say. For the minds of little animals must remain inscrutable.
Near them, on the grassy plateau, soldiers were unloading portable sheds in sections and erecting them; others were leveling hedges, felling small, isolated trees, uprooting bushes, and clearing away a line of wire pasture fencing.
Evidently this plateau was to be a base for some of the airmen operating along the Vosges or possibly, also, north and east from Verdun.
As they moved forward he looked about for a British uniform, but saw none. A soldier informed them that there were no British troops attached to the army of General Pau as far as he knew; two or three cavalry officers politely confirmed the statement, taking Warner to be an Englishman.
It was not until, following the deeply trodden sheep-walk, they passed the silver birch woods that they had any news of Halkett.
A squadron of hussars was already bivouacked there; their wagons were coming across the fields from the Dreslin road; officers, men, and horses had taken advantage of the woods to escape observation from air-scouts; and three batteries of artillery were parked in the Forêt de Saïs, where the cannoniers had already begun to cover everything with green branches.
As they passed through the Forêt de Saïs, out of which a shepherd with his shaggy dogs was driving his flock, they overtook an officer of hussars on foot, sauntering along the same path, a lighted cigarette between his white-gloved fingers.
He stepped aside into the bracken, courteously, in deference to Sister Eila, and lifted his hand to his shako in salute. But when he caught sight of Warner he stepped forward with a quick, boyish smile and held out his hand.
"Do you remember me?—D'Aurès? This is Monsieur Warner, is it not?"
They exchanged a handclasp; Warner presented him to Sister Eila.
"This is exceedingly nice," said the American cordially. "We—Sister Eila and I—are returning to the Château. I hope you will come with us."
"If I may venture to pay my respects——"
"You will be welcome, I know." He added, laughing: "Also, the ladies will be most interested in the fate of their horses and their automobiles."
The Vicomte d'Aurès reddened, but laughed:
"The Countess was most gracious, most patriotic," he said. "But one could expect nothing less from a De Moidrey. Nevertheless, I felt like a bandit that evening. I left them only a basket wagon and a donkey."
"Which have been greatly appreciated, Monsieur," said Sister Eila, smiling. And she told him about the removal of Captain Gray from the school to the Château.
"Oh, by the way," exclaimed D'Aurès, "we have a British aviator with us—a friend of yours, Sister Eila, and of Mr. Warner."
"Halkett!"
"Yes, indeed. It appears that Captain Halkett has specialized in this region, so he has been assigned to us. I have the honor of a personal acquaintance with him."
"Where is he?" asked Warner.
"He is near here somewhere. His machine, a Bristol, is to be parked with ours on the plateau yonder. I think they are erecting the hangars now."
They entered the wicket of the lodge gate and advanced along the drive toward the house.
Warner said:
"All this movement means the invasion of Alsace-Lorraine, I take it."
D'Aurès nodded.
"Could you give me an idea of the situation as it stands, Captain?"
"I can only guess. Briefly, we are moving on Strassburg from the Donon peaks to Château-Salins. As I understand it, our armies now stretch from the Sambre to the Seine, from the Meuse to the Oise.
"I can tell you only what is gossiped about among cavalry officers. We believe that we are leading a great counter-offensive movement; that it is our General Joffre's strategy to drive the Germans out of upper Alsace, block Metz and Strassburg, and, holding them there in our steel pincers, let loose our army on their flank and rear."
"And Longwy? And this drive just north of us at Ausone?"
D'Aurès smiled.
"Can you still hear the cannonade?"
They halted to listen; there was no longer that deadly rumor from the north.
"Verdun and Toul are taking care of that raid, I think," said D'Aurès pleasantly. "It comes from Metz, of course. Verdun must look out for the country between it and Longwy, too. That is not our route. Ours lies by Nancy toward Vic and Moyenvic, and through Altkirch to Mülhausen, and then—" he laughed—"it does not become a Frenchman to prophesy or boast. There were too many dreamers in 1870.
"I am telling merely the gossip of our camps. It is human to gossip when the day's work is over. But for the rest—route step and plod ahead!—That is what counts, not bragging or splendid dreams."
When they reached the terrace Warner fell back to speak to Asticot.
"I've arranged for you at the Golden Peach. Madame Arlon knows." He handed Asticot a key. "There's plenty to do in my studio down there. Get some wood and make cases for my canvases. Cover the chassis with toile and prime them with white lead. Use an ivory palette knife and let them have the sun when there is any and when there is no wind and dust. That will keep you busy until I send for you. Do you comprehend?"
"Yes, M'sieu'.... May I not walk behind M'sieu' when he takes the air?"
Warner scowled at him, but he looked so exactly like a shiftless, disreputable and mongrel dog who timidly desires to linger, yet is fearful of a kick, that the American laughed.
"A fine bargain I have in you!" he said. "You prefer rambling to work, it appears!"
"I prefer the vicinity of M'sieu'," said Asticot naïvely.
"Go back to the inn and see if you can do an honest hour's work!" retorted Warner; and he turned and rejoined Sister Eila, who had taken D'Aurès up the steps of the terrace.
It appeared that the ladies were on the north terrace. On the way through the hall, Sister Eila excused herself and mounted the stairs for a look-in on Gray. At the same moment, Peggy Brooks came out of the billiard room, saw D'Aurès, recognized him.
"Oh," she said, extending her hand, "I am so glad you have come back! How is my Minerva runabout?"
"I'm sorry I don't know," he replied, blushing; "I didn't steal it for myself, you see."
"You didn't steal it! It's a gift. It's mine to give. I give it to you! My sister took all the credit of giving away the horses and cars. But I insist on your having my Minerva runabout. It's a charming car. You'll fall in love with it if they let you drive it. Come out to the terrace and speak to my sister and to my dearest friend, Philippa Wildresse."
Warner, much amused to observe the capture of this young man, followed them out to the south terrace.
He certainly was an ornamental young man of enchanting manners, and his popularity was immediate.
To Warner Philippa came presently:
"Where have you been?" she asked. "And couldn't you have taken me?"
"Dear child, I was out before sunrise prowling about the hills with that vagabond at my heels—Asticot."
"What did you see?"
"Uhlans on Vineyard Hill, across the Récollette. Wildresse was with them."
"He!"
"Yes, the miserable spy! If he's not gone clear away some of D'Aurès' men had better try to round him up and get rid of him.... After that, Sister Eila and I went to the school. More Uhlans came sniffing around, but they cleared out in a hurry when our cavalry appeared. Our artillery shelled the Germans out of the Esser quarries—you must have heard the firing?"
"Yes. We all thought that the Germans had arrived. Poor Mr. Gray looked so disgusted!"
"Philippa, Halkett is here somewhere."
"Oh!" she exclaimed happily.
"He's here with his machine—an aëroplane of sorts—Bristol, I believe. No doubt he'll come up to the house when he has a chance. I suppose Sister Eila has gone up to tell Gray."
They had strolled around to the eastern parapet and now stood looking out over the tree tops.
"What has happened at Ausone?" she asked. "The cannon have stopped firing."
"I saw Ausone burning from Vineyard Hill. It's all knocked to pieces, Philippa. What I think has happened is this: troops from Verdun and Toul—perhaps from Chalons—have entered Ausone in time to save the fort. I suppose our infantry are intrenched along the Récollette and that there is going to be more fighting in Ausone Forest, which must be full of Germans."
"You don't think they'll come here?"
"I don't know. The army which you see below us everywhere in the valley is probably on its way to invade Alsace. D'Aurès thinks so. I suppose this line will be defended. We shall hear more cannonading, I fancy. Anyway, they are digging trenches to fall back on."
"Where?"
"Along the Récollette."
From where they were leaning on the stone balustrade, they could see pontoons spanning the river. Across them troops and wagons were passing; through every ford cavalry were splashing; the quarry bridge and road were packed with motor trucks escorted by cavalry; and on the Saïs highway artillery was still passing toward Ausone.
Her cheeks framed by her hands, elbows on the parapet, Philippa gazed at the moving host below. She wore a thin white gown; a scarf fell from her shoulders; her thick, beautiful hair was full of ruddy gleams, accenting the snowy neck and throat.
"If I set up my easel will you let me have a try at you?" he asked.
"Yes, but you've had no luncheon. I'll bring you something, and you can arrange your canvas while I'm gone."
But they found Sister Eila had arranged for him to lunch with Gray, so he sat with that battered and patient Englishman, chatting, watching the troops in the valley from the open window, and lunching comfortably.
Sister Eila glanced in, smiled, then went lightly away toward the eastern wing of the house, where fresh consignments of bandages were to be sterilized and stored in Red Cross boxes—gauze rolls, plugs for bullet wounds, body bandages, fracture bandages, arm slings, rolls of unbleached muslin, of cotton, of gauze.
As she passed the open door of the chapel, she halted, faced the altar and made her reverence. Then, crossing herself, she rose erect, turned to continue her way, and encountered Halkett face to face.
A bright flush leaped to her cheeks; his own face reddened to his hair under the bronze coat of tan.
"I am so glad to see you," she said steadily, offering her hand. "We heard you were in Saïs with your aëroplane. How did you happen to come into the east wing? It must have been closed when you were here before?"
"I have never before been in this house. I saw you cross the court as I mounted the terrace steps." He tried to ease the constraint in his voice. "I wanted to speak to you—first of anybody—in Saïs.... Are you well?"
"Perfectly. And you, Captain Halkett?"
"You seem thinner. You do not spare yourself."
"We scarcely have time to think of ourselves," she said, smiling. "I am trying to fit up a little hospital here; Madame de Moidrey offers the house."
"I understand that my friend, Captain Gray, is here?"
"Poor boy! I must not detain you any longer. You will desire to pay your respects to Madame de Moidrey and her sister and to the beautiful Miss Wildresse——"
"Philippa! Here?"
"You know her? Is she not lovely? I find her charming. And—so should all young men," she added with a little laugh. "Therefore—I shall no longer detain you, Captain Halkett——"
"May I—hope to see you again?"
"I hope so, indeed," she replied cheerfully. "Do you remain for a while in Saïs?"
"For a while, I think."
There fell a silence, which became a little strained. Sister Eila looked up at him from lowered eyes; then her face went white and she laid her hand flat against the chapel wall beside her, as though for support.
"Then—if I may hope to see you again—inspect your hospital, perhaps——"
She nodded, still leaning on the chapel wall.
So he went away swiftly, very straight in his field uniform, and she saw him cross the court, head erect, looking directly before him as though he saw nothing.
An immense fatigue seemed to weight her; still supporting herself against the wall, she turned and looked at the chapel door. Even on that grey day the light within was golden from the old glass.
Into that mellow stillness crept Sister Eila, her young head drooping, the metal crucifix swinging at her girdle from its rosary of wooden beads.
The painted saints stared at her; the painted angels all stood watching her; the Mother of God looked out from the manger, brooding, preoccupied, wonder-eyed; but the Child at her breast was smiling.
Then down on her knees fell Sister Eila; her slim hands clasped, clung, tightened, parted, and covered her face convulsively.
Very far away in the valley a trumpet spoke.
