“‘Lieutenant,’ he said, ‘it is my intention to capture the citadel to-night. Get together twenty-five of your men, and have them ready under the shadow of this house, but give no one a hint of what you intend to do with them. In one hour’s time leave this place with your men as quietly as possible, and make an attack on the western entrance of the citadel. Your attack is to be but a feint and to draw off their forces to that point. Still, if any of your men succeed in gaining entrance to the fort they shall not lack reward and promotion. Have you a watch?’ “‘Not one that will go, general; but I have an hourglass here.’ “‘Very well, set it running. Collect your men, and exactly at the hour lead them to the west front; it is but five minutes’ quick march from here. An hour and five minutes from this moment I expect you to begin the attack, and the instant you are before the western gate make as much noise as your twenty-five men are capable of, so as to lead the enemy to believe that the attack is a serious one.’ “Saying this, the general turned and made his way, heavy-footed, through the hall and down the stairway. “I set the hour-glass running, and went at once to call my men, stationing them where I had been ordered to place them. I returned to have a word with Gretlich before I departed on what I knew was a dangerous mission. Glancing at the hour-glass, I saw that not more than a quarter of the sand had run down during my absence. I remained in the doorway, where I could keep an eye on the hour-glass, while the girl stood leaning her arm against the angle of the dark passageway, supporting her fair cheek on her open palm; and, standing thus in the darkness, she talked to me in whispers. We talked and talked, engaged in that sweet, endless conversation that murmurs in subdued tone round the world, being duplicated that moment at who knows how many places. Absorbed as I was in listening, at last there crept into my consciousness the fact that the sand in the upper bulb was not diminishing as fast as it should. This knowledge was fully in my mind for some time before I realised its fearful significance. Suddenly the dim knowledge took on actuality. I sprang from the door-lintel, saying:-- “‘Good heavens, the sand in the hour-glass has stopped running!’ “I remained there motionless, all action struck from my rigid limbs, gazing at the hour-glass on the table. “Gretlich, peering in at the doorway, looking at the hour-glass and not at me, having no suspicion of the ruin involved in the stoppage of that miniature sandstorm, said, presently:-- “‘Oh, yes, I forgot to tell you it does that now and then, and so you must shake the glass.’
