After graduating from the school for infantry reserve officers in Graz, he participated in the Italian campaign during World War I. He participated in the first and secondbattles of the Isonzo, where he contracted Typhoid fever. After recovering, he was transferred to the Tyrolean sector of the front. For his bold attacks on the Italian stronghold on Monte Zebio he received the Golden Medal and transferred to the 87th Infantry regiment in Celje. In October 1918, he started to study law at the University of Graz.
In early November, Malgaj gathered a group of Slovene volunteers around Celje and marched into southeast Carinthia (in what is now known as Slovenian Carinthia). Together with General Maister and a company of volunteers composed of soldiers of the Army of the Kingdom of Serbia that were retreating from imprisonment in Austria, he reached Lavamünd and captured the Carinthian town of Völkermarkt (Slovene: Velikovec) in late November 1918.
Death
Accounts vary regarding his death. He either committed suicide on May 6, 1919, at Tolsti Vrh near Dravograd in Carinthia after being surrounded by Austrian soldiers, or he died after he accidentally activated a hand grenade attached to his belt. Unconfirmed rumors suggest he was shot by a group of soldiers from Serbia with whom he was allegedly in conflict.[2]
He was buried in the Carinthian town of Guštanj (now Ravne na Koroškem).
Legacy
On the 90th anniversary of Malgaj's death, his memoirs from 1914 to 1919 were published. A primary school in Šentjur was named after him.[3] Malgaj is well known in Slovenia because he led the group of Maister's soldiers that captured Meža and the Meža Valley for Slovenia after the First World War.
