With one later exception, the digitised manuscripts from the collections of the Military History Institute come from the 17th–19th centuries and contain mainly various treatises on fortification construction and military unit training, but also notes on military events (in particular the Austrian–Prussian War of 1866, shelf marks IIR C 16172, IIR C 16486 and IIR G 431, as well as the Seven Years’ War, shelf mark IIR F 355) and a military dictionary. The treatment of the history of the second battalion of Austrian field hunters in 1808–1863 by Anton Mudroch (IIR F 527) is exceptional for its size.
