Rambonet presented the peremptory missive, and waited forty-eight hours for the answer. He then returned to Wesel without any satisfactory reply. Frederick immediately issued a manifesto, declaring the reasons for his action, and ordered two thousand men, horse and foot, who were all ready for the emergence, to advance immediately to Maaseyk, one of the principal towns of the bishop, take possession of it and of the surrounding region, quarter themselves upon the people, enforce liberal contributions, and remain there until the bishop should come to terms.[34] The solid, compact army, with infantry, artillery, and cavalry in the best possible condition, advanced at the double-quick. Arriving at the gates of Maaseyk, not a moment was spent in parleying. “Open the gates instantly,” was the summons, “or we shall open them with the petard.” With great courtesy of words, but pitiless energy of action, General Borck, who was in command, fulfilled his commission. A contribution was exacted of fifteen thousand dollars, to be paid within three days; sufficient rations were to be furnished daily for the troops, or the general, it was stated, would be under the painful necessity of collecting them for himself. Two hundred and fifty dollars a day were to be provided for the general’s private expenses. Remonstrances were of no avail. Resistance was not to be thought of. The poor old bishop called loudly upon the Emperor of Germany for help. The territory of the Bishop of Liege was under the protection of the empire. The Emperor Charles VI. immediately issued a decree ordering Frederick to withdraw his troops, to restore the money which he had extorted, and to settle the question by arbitration, or by an appeal to the laws of the empire. This was the last decree issued by Charles VI. Two weeks after he died. Frederick paid no regard to the remonstrance of the emperor. The bishop, in his distress, applied to the French for aid, and then to the Dutch, but all in vain. He then sent an embassy to Berlin, proposing to purchase Herstal. The king consented to sell upon the same terms his father had offered, adding to the sum the expenses of his military expedition and other little items, bringing the amount up to one hundred and eighty thousand dollars. The money was paid, and the Herstal difficulty was settled. This was Frederick’s first act of foreign diplomacy. Many severely censured him for the violent course he pursued with a power incapable of resistance. All admitted the energy and sagacity which he had developed in the affair.
