Our hero was ten years old when the King was forced to sign the disastrous peace of Tilsit, and according to the usual custom he was raised at this age to the rank of officer. The great event should properly have taken place March 22, 1807, but owing to the unsettled state of the country his father presented him with his appointment on New Years’ Day, just before the royal family left Königsberg for Memel, and he was made ensign in the newly formed regiment of foot-guards. At Christmas he was advanced to a second-lieutenantship, and on June 21, 1808, marched with his regiment back to Königsberg. A report made about this time states: “Prince William, during his first two years of service with the Prussian infantry, has become familiar with every detail of army life and is already heart and soul a soldier,”—a tribute well deserved by the young officer, for he was faithful and industrious and devoted to his profession. The two following years that the royal family remained in Königsberg were an important period in the life of Prince William. The sole tuition of Delbrück no longer satisfied the Queen, and on the advice of Baron von Stein, she appointed General Diericke and Colonel Gaudy as governors for the Crown Prince, and Major von Pirch and Professor Reimann for Prince William. At the same time Karl August Zeller, a pupil of the Queen’s honored Swiss teacher Pestalozzi, was summoned to Königsberg and given charge of the school system. He also assisted in the education of Prince William, whose untiring zeal and industry caused him to make steady and rapid progress in all branches of learning. His best efforts, however, were given to his military duties, and he eagerly treasured up everything that was said at court of famous generals and heroes. On November 12, 1808, he paraded for the first time with his regiment. In September of the following year he was present at the placing of the memorial tablets to the first East Prussian Infantry in the palace chapel at Königsberg, and after the court had returned to Berlin, he entered that city with his regiment on his parents’ wedding anniversary, December 24, 1809. It was a melancholy home-coming, and never again did our hero make so sad an entry into his capital, for in spite of the joy with which the citizens welcomed the return of their beloved sovereigns once more, the country’s shameful bondage under the yoke of Napoleon lay heavily on all hearts. No one felt the disgrace more keenly than Queen Louise, however: it rankled in her bosom and gradually consumed her strength till her health began to give way under it.
