Johann Bonaventura von Rauch (25 July 1740 – 9 February 1814) was a Prussian Army major general. His sons Gustav, Leopold and Friedrich Wilhelm also took up military careers and became general as well.
On Charles William Ferdinand's recommendation, Rauch moved to the Prussian Army in August 1777. On personal instructions from Frederick II of Prussia[1] he became a teacher at the mining corps in the Königsberg garrison. In 1788 Frederick William II of Prussia founded a Royal Engineering Academy in Potsdam - Rauch moved there and was promoted to major. The institution also took part in military surveying and so Rauch travelled to Silesia in 1791 and the Králický Sněžník Mountains in spring 1792. He also began to write treatises on military theory and to produce collections of maps.
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. He then caught dysentery and stayed in a hospital in Koblenz until November 1792. The king made Rauch a lieutenant colonel in 1796 and put him in charge of the Engineering Academy. He became a major general in 1805 and was made deputy governor of Stettin on the outbreak of the War of the Fourth Coalition in summer 1806, with the 77-year-old lieutenant general von Romberg as governor. After the defeats in the battle of Jena-Auerstedt, Prussia's field army retreated and began to split up. Romberg's morale collapsed and when eight hundred French cavalry arrived before Stettin on 29 October 1806 he surrendered immediately without waiting to assess the size of the enemy force, which was vastly dwarfed by Stettin's garrison of 5,184.
Rauch agreed to the surrender[2] and so on 1 December was dishonourably discharged from the Prussian Army. He was later placed under house arrest and then in 1809 sentenced to life imprisonment in the Spandau Fortress.[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.
