THREE:478 The latter part of June, an army of a hundred thousand Russians, having crossed the Vistula, was concentrated, under General Soltikof, at Posen, on the River Warta, in Poland. They were marching from the northeast to attack the Prussian forces near Landshut in their rear. General Daun, with a still larger force of Austrians, was confronting Frederick on the southwest. The plan of the allies was to crush their foe between these two armies. Frederick had lost the ablest of his generals. The young men who were filling their places were untried.The queen, looking reproachfully at Grumkow, remarked, I know full well to whom I owe all this. She then excused herself, saying that she was not well, and retired to her apartment. There she communicated to the anxious Wilhelmina the cruel message of the king. Sophie Dorothee then wrote a very earnest letter to Queen Caroline, the wife of George II., imploring that all obstacles in the way of the marriage of Wilhelmina with the Prince of Wales might be withdrawn. The idea of marriage with either Weissenfels or Schwedt was dreadful. But, on the other hand, the wrath of the king, the divorce of the queen, and75 the imprisonment of both mother and daughter in the chateau of Oranienburg, were also dreadful. Fritz was taken into the councils of his mother and sister. It was decided that he should also write to his aunt, urging his suit for the Princess Amelia. It is true that George II. was ready to accede to this marriage, but Frederick William threw obstacles in the way. It was probably the hope of Fritz to secure Amelia, notwithstanding his fathers opposition. The ready pen of Wilhelmina was employed to draft the letter, which her brother submissively copied. As it was not probable, in the intricacies in which the question was now involved, that both marriages could take place together, Fritz wrote pleading for the marriage of Wilhelmina at once, pledging his word that he would remain faithful to the Princess Amelia.
