High Quality Content by WIKIPEDIA articles! Johann Adolf Freiherr von Thielmann (27 April 1765 10 October 1824) was a Saxon and Prussian cavalry soldier from Dresden. Entering the Saxon cavalry in 1782, he saw service against the French in the Revolutionary Wars and in the Jena campaign. When, after the disaster of Jena, Saxony allied herself with her conqueror, Thielmann accompanied the Saxon contingent which fought at the siege of Danzig and at Friedland. In 1809, as colonel of Freikorps, he opposed the advance of the Austrians into Saxony, and was rewarded for his services with the grade of major-general, further promotion to lieutenant-general following in 1810. As commander of the Saxon Heavy Cavalry Brigade he took part in the advance on Moscow two years later, and his conduct at Borodino attracted the attention of Napoleon, who took Thielmann into his own suite. His own sovereign at the same time made him Freiherr. In the war of the Sixth Coalition, Thielmann took a prominent part.
