"On August 14th, at about four o'clock in the afternoon, the expected storm burst; for twenty-five hours the invisible siege-guns poured their torrent of projectiles on the fort. Flares of fire and dense clouds of smoke belched through the crevices. As the enemy's batteries could not be located, their fire could not be answered. The artillerists of the garrison were then taken to the spacious chief gallery, which offered a safe refuge under its vault, about two and a half to three yards thick. Outside the sentries were watching. In the parts near the entrance it was unendurable; the heavy projectiles from the guns mounted in the town had nibbled away the outer wall, only a yard and a half thick. There were as yet no casualties among the garrison; calmly they waited for the infernal tempest to subside and the enemy to storm the fort, for they had sworn to repulse the assault. "General Leman, Commander Naessens, and all the officers were splendid in their imperturbable courage. They found the words that went straight to the hearts of their men. These fellows looked more like bronze statues than human beings. The projectiles hammered at the walls and smashed huge pieces, penetrating into the parts near the entrance. The rest of the fort withstood splendidly the hurricane of hostile steel and fire. During the night the bombardment stopped, and then the commanding officer went to inspect the cupolas. "The larger ones had suffered little; but the majority were jammed by fragments of concrete and steel, which struck between the armour and the front-armour. The small quick-fire cupolas had not been touched by any projectile. 'It is all right,' he said, 'we shall be able to repulse the enemy's attack.' "At dawn the bombardment started again, but only the front was seriously damaged. The garrison stood as firm as a rock. Here and there the beginnings of a fire were soon extinguished. "Then a frightful thing happened. The men had finished breakfast, some were sleeping quietly in spite of the thundering noise. The assault was expected to commence during the next night. "And then the disaster followed suddenly. At about five o'clock a tremendous explosion shook the fort to the foundations; the powder-magazine had caught fire. It is impossible to describe the appalling results of that explosion; the entire middle-part of the fort collapsed in a stupendous cloud of flames, smoke and dust; it was an awful destruction, an immense avalanche of masses of concrete, fragments of armour, which in their fall crushed to death nearly the whole of the garrison. From this fantastical, confused mass, overwhelming clouds of suffocating smoke escaped through some crevices and holes.
