The prince was withdrawn, and placed in a room where two sentries watched over him with fixed bayonets. The king malignantly assumed that the prince, being a colonel in the army and attempting to escape, was a _deserter_, whose merited doom was death. General Mosel urged the king not to see his son again, as his presence was sure to inflame his anger to so alarming a pitch. The father did not again see him for a year and three days. A stern military commission was, however, appointed to interrogate the prince from questions drawn up by the king. The examination took place the next day. The prince confessed that it was his intention to cross the Rhine at the nearest point, and to repair to Strasbourg, in France. There he intended to enlist incognito as a volunteer in the French army. He refused to tell how he obtained his money, or to make any revelations which would implicate his friends Katte and Keith. [Illustration: FREDERICK WILLIAM ENRAGED.] As this report was made to the king, he exclaimed, angrily, “Let him lie in ward, then, and await the doom which the laws adjudge to him. He is my colonel. He has attempted to desert. He has endeavored to induce others to desert with him. The law speaks plainly enough as to the penalty for such crimes.” In the mean time, the queen and Wilhelmina, at Berlin, unconscious of the dreadful tidings they were soon to receive, were taking advantage of the absence of the king in seeking a few hours of social enjoyment. They gave a ball at the pretty little palace of Monbijou, on the banks of the Spree, a short distance out from Berlin. In the midst of the entertainment the queen received, by a courier, the following dispatch from Frederick William: “I have arrested the rascal Fritz. I shall treat him as his crime and his cowardice merit. He has dishonored me and all my family. So great a wretch is no longer worthy to live.” Wilhelmina, in the following graphic narrative, describes the scene: “Mamma had given a ball in honor of papa’s birthday. We recommenced the ball after supper. For six years I had not danced before. It was new fruit, and I took my fill of it, without heeding much what was passing. Madam Bulow, who, with others, had worn long faces all night, pleading illness when one noticed it, said to me several times, “‘It is late. I wish you had done.’ “‘Oh dear me!’ I exclaimed; ‘do let me have enough of dancing this one new time. It may be long before it comes again.’ “She returned to me an hour after, and said, with a vexed air, ‘Will you end, then? You are so engaged you have eyes for nothing.’ “I replied, ‘You are in such a humor I know not what to make of it.’ “‘Look at the queen, then,’ she added, ‘and you will cease to reproach me.’
