To Ned's surprise his aunt, when the alarm bells rung, had sallied out from her house accompanied by the two girls. She carried with her half a dozen balls of flax, each the size of her head. These had been soaked in oil and turpentine, and to each a stout cord about two feet long was attached. The girls had taken part in the work of the preceding day, but when she reached the breach she told them to remain in shelter while she herself joined the crowd on the walls flanking the breach, while Ned took part in the front row of its defenders. Frau Plomaert was slow, but she was strong when she chose to exert herself, and when the conflict was at its thickest she lighted the balls at the fires over which caldrons of oil were seething, and whirling them round her head sent them one by one into the midst of the Spanish column. "Three of them hit men fairly in the face," she said to one of her neighbours, "so I think I have done: my share of today's work." She then calmly descended the wall, joined her daughters and returned home, paying no attention to the din of the conflict at the breach, and contended that she had done all that could be expected of her. On reaching home she bade the girls take to their knitting as usual, while she set herself to work to prepare the midday meal. A few days later the Prince of Orange sent from Sassenheim, a place on the southern extremity of the lake, where he had now taken up his headquarters, a force of 2000 men, with seven guns and a convoy of wagons with ammunition and food towards the town, under General Batenburgh. This officer had replaced De la Marck, whose brutal and ferocious conduct had long disgraced the Dutch cause, and whom the prince, finding that he was deaf alike to his orders and to the dictates of humanity, had now deprived of his commission. Batenburgh's expedition was no more fortunate than that of De la Marck had been. On his approach to the city by night a thick mist set in, and the column completely lost its way. The citizens had received news of its coming, and the church bells were rung and cannon fired to guide it as to its direction; but the column was so helplessly lost, that it at last wandered in among the Spaniards, who fell upon them, slew many and scattered the rest--a very few only succeeding in entering the town. Batenburgh brought off, under cover of the mist, a remnant of his troops, but all the provisions and ammunition were lost.
