on the island of Elba. The Vienna Congress and the personality of Archduke Karl are documented in detail, and the so-called Info-Points – interactive touchscreen monitors which visitors can use - provide further information on the events of this period using contemporary graphics, maps, and biographical notes. Hall III is also called the Hall of Revolutions because the exhibition it contains begins with the French Revolution and ends with the Revolution of 1848. Hall IV – Field Marshal Radetzky and his era (1848–1866) Hall IV is dedicated to Joseph Radetzky von Radetz and his era. He joined the Imperial Army as a cadet already in 1784 and fought in the last Ottoman War under commanders Lacy and Laudon. After an impressive 72 years of service, he was retired only after he reached the age of 90. He served under a total of five emperors and participated in no fewer than 17 campaigns, for which he was awarded 146 Austrian and foreign medals. His victories against Sardinia-Piemont at Santa Lucia, Verona, Vicenza, and Custoza in 1848 and those in Mortara and Novara in 1849 consolidated the reign of young emperor Franz Joseph, at least temporarily. Poet Franz Grillparzer even composed an ode to Radetzky: "Glück auf, mein Feldherr, führe den Streich! Nicht bloß um des Ruhmes Schimmer – In deinem Lager ist Österreich!", for which the poet was awarded an honorary cup now on display in the hall. The Radetzky hall also contains numerous paintings of contemporary artists such as Albrecht Adam and Wilhelm Richter, which make his military campaigns come alive. Following the death of Radetzky, the tables turned radically in Northern Italy for young Emperor Franz Joseph, who had only recently ascended to the throne on 2 December 1848: In the battle of Solferino in 1859, at which Franz Joseph was personally in command of the troops, Austria suffered a heavy defeat. The atrocity of the battle and the helplessness of the wounded soldiers prompted Henry Dunant to found the Red Cross, and led to the agreement of the Geneva Convention. The flow of young men to the Imperial Army, however, did not recede, because the "magic of the uniform" continued to cast its spell, illustrated by the numerous uniforms of different branches and regiments on display in the hall. As of 1864, the Austrian artillery was in possession of developments that rendered it superior to the enemy's guns,
