Part of the Yugoslav 7th Army, it was deployed west and southwest of Ljubljana in the Julian Alps, along the western border with Italy from Mount Bička north to Mount Blegoš. It was not heavily engaged during the first few days of the invasion, but from 9 April it withdrew steadily due to retirements on the right flank of the 7th Army and in the face of the advancing German XXXXIX Mountain Corps of General der Infanterie Ludwig Kübler. The Italian Second Army, commanded by Generale designato d'Armata Vittorio Ambrosio, joined the invasion on 9 April, and the 14th Panzer Division linked up with Italian thrusts further south to encircle the remnants of the 7th Army. The division surrendered on 12 April, along with the rest of the 7th Army.
