III decreed that _Turnen_ should absolutely cease throughout Prussia. Jahn was kept at Spandau for a few days, transferred to Küstrin July 17, brought back to Berlin for trial early in October, and by an official report of February 15, 1820, the chief charges against him were declared null and void. A cabinet order of May 31 released him from arrest, but stipulated that he should reside, until further notice, in the fortress of Kolberg, on the Baltic, and placed him under the oversight of the commanding officer there. The 1000 thalers which he had been receiving from the state—800 as teacher of gymnastics and 200 from the Ministry of War—was to be continued. After prolonged investigation the supreme court at Breslau, by its decision of January 13, 1824, absolved him from all suspicion of complicity in the murder of Kotzebue, but sentenced him to two years additional confinement in a fortress on account of “repeated irreverent and insolent utterances regarding existing conditions and regulations in the state.” From this decision Jahn appealed, and sent in his “self-defence” (_Selbstvertheidigung_, finished October 9, 1824) to the supreme court at Frankfort-on-the-Oder, by which body he was entirely acquitted March 15, 1825. But a cabinet order of May 3 forbade his living in Berlin or within a radius of ten miles from the capital, or in any city containing a university or higher school for boys; and wherever he settled he was to remain under police surveillance. The thousand-thaler pension remained unchanged. Jahn selected for his home the Thuringian town of Freyburg-on-the-Unstrut, about thirty miles west and south of Leipsic. The accession of Frederick-William IV to the throne of Prussia in 1840 was followed by the final removal of all police restrictions, and brought him also the long-expected decoration of the Iron Cross. By a cabinet order of June 6, 1842, gymnastics was “formally recognized as a necessary and indispensable part of male education and received into the circle of means for popular education.” _Turnen_ began to revive with this, but though Jahn followed its development with interest and received hospitably the turners who visited his home, he took no active part in the movement. In 1844 he attended the centennial exercises of his first school, the _Gymnasium_ at Salzwedel. Four years later he was present as a delegate in the German national assembly at Frankfort-on-the-Main, but returned to his home bitterly disappointed. He died at Freyburg, after a brief illness, October 15, 1852.[50]
