In 2019, the Military History Institute Prague provided access to another 36 manuscripts, most of which come from the 18th century and are written in German. A homogeneous group is formed by several treatises by Johann Andreas von Traitteur on the military events in the Rhineland at the end of the 18th century; other works include especially texts on military exercises, Austrian, Saxon and Prussian military orders, theoretical works on fortification engineering, and historical-military reports on various conflicts (e.g. the Austro-Turkish War in 1787–1791 in IIR F 373 and the campaign in Italy in 1797 in IIR F 469). French texts are represented e.g. by the work on the Fortress of Arad in Romania by Jean Baptiste d'Estienne de Vauguez (IIR D 780), three volumes on military theory (IIR F 252/1–3), and a binder’s volume containing texts concerning fortifications (IIR B 2335).
