Bonaventura von Rauch

Under Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel he took part in the closing phases of the Seven Years' War, namely in the 1761-62 sieges of Kassel (in which he was wounded), Meppen and Ziegenhain.

In 1788 Frederick William II of Prussia founded a Royal Engineering Academy in Potsdam - Rauch moved there and was promoted to major.

He served as a captain of guides on the Prussian General Staff during the French campaign and helped take the fortresses at Longwy and Verdun.

[3] His fate led to protests within Prussia's officer corps, especially since Romberg had only ever been a scientist and lecturer and had never before commanded an army in the field.

Frederick William's queen-consort Louise of Mecklenburg-Strelitz took up the cause, but she was only able to get the sentence commuted to life imprisonment in the town of Spandau rather than the fortress, though she did also get half of Rauch's pension as a major general reinstated.
