During World War I he fought on the Eastern Front, where he seriously injured.

After the establishment of the Hungarian Soviet Republic he demobilized.

As a minister he favoured the Allies examining the cessation of its commission's function, and he covered the gun-running being directed into the country.

He also supported the Austrian Heimwehr in the interest of a right wing extremist military coup.
