Day dawned, at length, after the feverish, night, and, the Admiral prepared for the assault. Within the fortress reigned a death-like stillness, which inspired a sickening suspicion. Had the city, indeed, been carried in the night; had the massacre already commenced; had all this labor and audacity been expended in vain? Suddenly a man was descried, wading breast-high through the water from Lammen towards the fleet, while at the same time, one solitary boy was seen to wave his cap from the summit of the fort. After a moment of doubt, the happy mystery was solved. The Spaniards had fled, panic struck, during the darkness. Their position would still have enabled them, with firmness, to frustrate the enterprise of the patriots, but the hand of God, which had sent the ocean and the tempest to the deliverance of Leyden, had struck her enemies with terror likewise. The lights which had been seen moving during the night were the lanterns of the retreating Spaniards, and the boy who was now waving his triumphant signal from the battlements had alone witnessed the spectacle. So confident was he in the conclusion to which it led him, that he had volunteered at daybreak to go thither all alone. The magistrates, fearing a trap, hesitated for a moment to believe the truth, which soon, however, became quite evident. Valdez, flying himself from Leyderdorp, had ordered Colonel Borgia to retire with all his troops from Lammen. Thus, the Spaniards had retreated at the very moment that an extraordinary accident had laid bare a whole side of the city for their entrance. The noise of the wall, as it fell, only inspired them with fresh alarm for they believed that the citizens had sallied forth in the darkness, to aid the advancing flood in the work of destruction. All obstacles being now removed, the fleet of Boisot swept by Lammen, and entered the city on the morning of the 3rd of October. Leyden was relieved.
