Poland, ever in turmoil, was at this time choosing a king. The emperor advocated the claims of August of Saxony. France urged Stanislaus, a Polish noble, whose daughter had married the French dauphin. War ensued between France and Germany. Frederick William became the ally of the emperor. An army of ten thousand men, admirably equipped and organized, was upon the march for the Rhine, to act with the emperor against France. The Crown Prince was very eager to join the expedition, and obtained permission to do so. On the evening of the 29th of June, 1734, there was a grand ball at the little palace of Monbijou. At three o’clock in the morning the Crown Prince changed his ball-dress for a military suit, and with his staff set out at full speed for the seat of war. They traveled in carriages, by post, night and day, hastening to take part in the siege of Philipsburg. A little after midnight on the morning of the 2d of July, they reached Hof, having traveled two hundred miles, and having two hundred miles still farther to go. At Hof the prince was within thirty-five miles of Baireuth, to which place Wilhelmina had some time before returned. He was very anxious to see her. But his father had strictly prohibited his going through Baireuth, under the assumption that it would occasion loss of time. Frederick made arrangements with Wilhelmina, who was in a very delicate state of health, to meet him at Berneck, about twelve miles from Baireuth. But, unfortunately, one of the carriages which conveyed the Crown Prince and his companions lost a wheel, which detained them several hours. The commands of the king were explicit that the Crown Prince should not be separated from the rest of the company. Thus Wilhelmina, upon reaching Berneck, according to appointment, did not find her brother there, and could hear nothing from him. The prince, upon his arrival at Hof, wrote as follows to his sister “Hof, July 2, 1734, not long after 4 A.M. “MY DEAR SISTER,--Here I am, within six leagues of a sister I love, and I have to decide that it will be impossible to see her after all. I have never so lamented the misfortune of not depending on myself as at this moment. The king being very sour sweet on my score, I dare not risk the least thing. A week from next Monday, when he arrives himself, I should be queerly treated in the camp if I were found to have disobeyed orders. “The queen commands me to give you a thousand regards from her. She appeared much affected at your illness. But I can not warrant you how sincere it was, for she is totally changed, and I no longer comprehend her. She has done me all the hurt with the king she could. As to Sophie, she is no longer the same. She approves all the king says or does, and is charmed with her big clown of a bridegroom.
