Don Marcelo’s eye was caught by a sparkling circle of glass, a monocle fixed upon him with aggressive insistence.  A lank lieutenant with the corseted waist of the officers that he had seen in Berlin, a genuine Junker, was a few feet away, sword in hand behind his men, like a wrathful and glowering shepherd.

“What are you doing here?” he said gruffly.

Desnoyers explained that he was the owner of the castle.  “French?” continued the lieutenant.  “Yes, French.” . . .  The official scowled in hostile meditation, feeling the necessity of saying something against the enemy.  The shouts and antics of his companions-at-arms put a summary end to his reflections.  They were all staring upward, and the old man followed their gaze.

For an hour past, there had been streaking through the air frightful roarings enveloped in yellowish vapors, strips of cloud which seemed to contain wheels revolving with frenzied rotation.  They were the projectiles of the heavy German artillery which, fired from various distances, threw their great shells over the castle.  Certainly that could not be what was interesting the officials!

He half shut his eyes in order to see better, and finally near the edge of a cloud, he distinguished a species of mosquito flashing in the sunlight.  Between brief intervals of silence, could be heard the distant, faint buzz announcing its presence.  The officers nodded their heads.  “Franzosen!” Desnoyers thought so, too.  He could not believe that the enemy’s two black crosses were between those wings.  Instead he saw with his mind’s eye, two tricolored rings like the circular spots which color the fluttering wings of butterflies.

This explained the agitation of the Germans.  The French air-bird remained motionless for a few seconds over the castle, regardless of the white bubbles exploding underneath and around it.  In vain the cannon nearest hurled their deadly fire.  It wheeled rapidly, and returned to the place from which it came.

“It must have taken in the whole situation,” thought the old Frenchman.  “It has found them out; it knows what is going on here.”

He guessed rightly that this information would swiftly change the course of events.  Everything which had been happening in the early morning hours was going to sink into insignificance compared with what was coming now.  He shuddered with fear, the irresistible fear of the unknown, and yet at the same time, he was filled with curiosity, impatience and nervous dread before a danger that threatened and would not stay its relentless course.

Outside the park, but a short distance from the mud wall, sounded a strident explosion like a stupendous blow from a gigantic axe—­an axe as big as his castle.  There began flying through the air entire treetops, trunks split in two, great chunks of earth with the vegetation still clinging, a rain of dirt that obscured the heavens.  Some stones fell down from the wall.  The Germans crouched but with no visible emotion.  They knew what it meant; they had been expecting it as something inevitable after seeing the French aeroplane.  The Red Cross flag could no longer deceive the enemy’s artillery.
