He was often employed in missions to various capitals, and he appeared in the field in 1854 at the head of the Austrian army which intervened so effectually in the Crimean War. In 1859 he was sent to the Second Italian War of Independence after the early defeats. He became field-marshal in 1860, and a year later, on resigning his position as chief-of-staff, he was made captain of the Trabant guard. He died in Vienna in 1870.
