both in terms of precision and manoeuvrability. This is demonstrated by the exhibited M 1863 field gun. The situation was exactly the opposite in the case of infantry weaponry, however, exemplified by the comparison between the Austria muzzle-loader system and the Prussian breech-loading needle rifle. The defeat of the Austrian army at the battle of Königgrätz in 1866 is the subject of an impressive monumental painting by Vaclav Sochor. A separate room is dedicated to the fate of the emperor's brother Ferdinand Maximilian, who ascended to the throne of Mexico in 1864, only to be executed there at the order of Benito Juárez in 1867. The collection on display features private items which were partly obtained from Miramare Castle, and which provide evidence of his unfortunate reign in Mexico (including his death mask). Hall V – Franz Joseph Hall and Sarajevo (1867–1914) Apart from the uniforms and guns, when entering the Franz Joseph Hall visitors immediately notice the 34 uniform presentations of the Imperial and Royal Army painted by Oskar Brüch for the Budapest Millennium Exhibition in 1896. A section of the hall is devoted to the 1878 occupation campaign in Bosnia and Herzegovina under the command of Joseph Philippovich von Philippsberg. The central display cabinet in the hall shows the technical innovations of the army prior to 1914, such as the model of a chain-driven combat vehicle (Burstyn tank) that was never actually built, the first powerful machine-gun of the Imperial and Royal Army (Schwarzlose) and the model of a field kitchen. Also on display are examples of the beginnings of military aviation, such as models of the Etrich Taube, the Lohner Pfeilflieger, and the M 1896 k.u.k. military balloon. The highlight of the exhibition is certainly the display cabinet with the personal items of Emperor Franz Joseph. These are the only ones accessible to the public, and they include his campaign and gala surcoats, his medals, cigar holders, and pince-nez. The next items on display here are the magnificent uniforms of the Arcièren Imperial Guards, a strong contrast to the uniforms of the Imperial and Royal Army before the outbreak of World War I on the opposite side. Certainly of particular significance are the personal utensils of the Chief of General Staff of the k.u.k. Army, Franz Conrad von Hötzendorf. A separate bay is dedicated to the Assassination of Archduke Franz Ferdinand, which directly triggered World War I.
