As a reward he was sent to Maria Theresa in Vienna with the news of the victory and was awarded the Order of the Golden Fleece.

At the beginning of the war, he commanded 28,000 men, who initially stood near Leitmeritz, blocking access to Bavaria.

Along with his wife, Liechtenstein was one of Joseph II's closest courtiers and rose to field marshal and chamberlain.

In the Russo-Turkish War, in 1788, he was given command of an army of 36,000 men in Croatia and took part in the siege of Dubitza.

He was buried in the newly-built mausoleum of the younger line of the House of Liechtenstein, at the Church of All Saints in Kromau.
