The fever of the Prince had, meanwhile, reached its height. He lay at Rotterdam, utterly prostrate in body, and with mind agitated nearly to delirium, by the perpetual and almost unassisted schemes which he was constructing. Relief, not only for Leyden, but for the whole country, now apparently sinking into the abyss, was the vision which he pursued as he tossed upon his restless couch. Never was illness more unseasonable. His attendants were in despair, for it was necessary that his mind should for a time be spared the agitation of business. The physicians who attended him agreed, as to his disorder, only in this, that it was the result of mental fatigue and melancholy, and could be cured only by removing all distressing and perplexing subjects from his thoughts, but all the physicians in the world could not have succeeded in turning his attention for an instant from the great cause of his country. Leyden lay, as it were, anxious and despairing at his feet, and it was impossible for him to close his ears to her cry. Therefore, from his sick bed he continued to dictate; words of counsel and encouragement to the city; to Admiral Boisot, commanding, the fleet, minute directions and precautions. Towards the end of August a vague report had found its way into his sick chamber that Leyden had fallen, and although he refused to credit the tale, yet it served to harass his mind, and to heighten fever. Cornelius Van Mierop, Receiver General of Holland, had occasion to visit him at Rotterdam, and strange to relate, found the house almost deserted. Penetrating, unattended, to the Prince's bed-chamber, he found him lying quite alone. Inquiring what had become, of all his attendants, he was answered by the Prince, in a very feeble voice, that he had sent them all away. The Receiver-General seems, from this, to have rather hastily arrived at the conclusion that the Prince's disorder was the pest, and that his servants and friends had all deserted him from cowardice.
