To become king of Poland the Saxonian elector had to convert to Catholicism. A quite difficult and troublesome decision as Saxony was a protestant country for centuries.
Likely some aristocrats and staff at the court of Dresden also converted, probably also Christian Huthsteiner. At least his son was of catholic religion when they came back to Saxony in 1763.
Heinrich Christian made his fortune within the Saxonian army. He joined the artillery corps and later was promoted to a mathematics at the artillery school. He had to fight together with the french troops during the Napoleonic wars.
In 1809 he was awarded with the Medal of the order of St. Heinrich and on 06.07.01813 with the medal of the French Legion of Honour.
He rank was Major when he defended the fortress of Glogau during the allied siege in 1813, but had to capitulate finally after this very long lasting siege. His detailed reports are preserved in the states archive of Saxony, Dresden.
While he was defending Glogau his son Friedrich August died at the siege of Torgau.
In 1830 Heinrich Christian died in Löwenberg ranked as colonel. It seems that he got the title ‘von’ i.e. he became ennobled some years before.
