The division was based in Friuli and named for the river Isonzo, along which Italy and Austria-Hungary had fought twelve battles during World War I.

[1][4][5] On 10 June 1940, the day Italy entered World War II, the Isonzo was deployed along the border with Yugoslavia near Postojna and performed security duties from Kalce, Logatec to Javornik Hills.

The division remained in the area on border patrol duty until the invasion of Yugoslavia on 6 April 1941.

In 1943 the Isonzo fought a series of battles against the increasing number of partisans in Slovenia, abandoning gradually much of the countryside and concentrating on the defence of the main roads.
