THREE:The expenses of the war were enormous. Frederick made a careful estimate, and found that he required at least three hundred and seventy-five thousand dollars a month. He could not carry on another campaign with less than four million five hundred thousand dollars. He had been expecting that Louis XV., who in person was in command of the French army on the Rhine, would send him a re-enforcement of sixty thousand troops to enable him to crush the forces of Prince Charles. But week after358 week passed, and no re-enforcements came. The French, intent upon their conquest, were as selfishly pursuing their own interests on the Rhine as Frederick was pursuing his in Silesia.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 Fredericks 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.
