After having been forced to sue for peace with Sweden in 1700, the Danish army was much larger than the kingdom could support. The king then decided to put almost half of the army under Allied command during the War of the Spanish Succession. Ten thousand soldiers served as an auxiliary corps to the Habsburg Monarchy, fighting under Eugene of Savoy in northern Italy, including the battles of Cremona and Luzzara. Later they participated in the suppression of the Hungarian insurgency.
