The Fall Of Haarlem
After the terrible repulse inflicted upon the storming party, Don Frederick perceived that the task before him was not to be accomplished with the ease and rapidity he had anticipated, and that these hitherto despised Dutch heretics had at last been driven by despair to fight with desperate determination that was altogether new to the Spaniards. He therefore abandoned the idea of carrying the place by assault, and determined to take it by the slower and surer process of a regular siege. In a week his pioneers would be able to drive mines beneath the walls; an explosion would then open a way for his troops. Accordingly the work began, but the besieged no sooner perceived what was being done than the thousand men who had devoted themselves to this work at once began to drive counter mines.

Both parties worked with energy, and it was not long before the galleries met, and a desperate struggle commenced under ground. Here the drill and discipline of the Spaniards availed them but little. It was a conflict of man to man in narrow passages, with such light only as a few torches could give. Here the strength and fearlessness of death of the sturdy Dutch burghers and fishermen more than compensated for any superiority of the Spaniards in the management of their weapons. The air was so heavy and thick with powder that the torches gave but a feeble light, and the combatants were well nigh stifled by the fumes of sulphur, yet in the galleries which met men fought night and day without intermission. The places of those who retired exhausted, or fell dead, were filled by others impatiently waiting their turn to take part in the struggle. While the fighting continued the work went on also. Fresh galleries were continually being driven on both sides, and occasionally tremendous explosions took place as one party or the other sprung their mines; the shock sometimes bringing down the earth in passages far removed from the explosions, and burying the combatants beneath them; while yawning pits were formed where the explosions took place, and fragments of bodies cast high in the air. Many of the galleries were so narrow and low that no arms save daggers could be used, and men fought like wild beasts, grappling and rolling on the ground, while comrades with lanterns or torches stood behind waiting to spring upon each other as soon as the struggle terminated one way or the other.
