Elements of the division saw action for the first time on 19 December when they were used as emergency troops to plug gaps in the front.

The division continued to fight in northern Croatia and southern Austria until the end of the war.

At that point, the division crossed the Carnic Alps and entered Carinthia where it surrendered to British forces.

The personnel of the Szent László Infantry Division were allowed to keep their weapons until discussions between the British and Yugoslav partisans were settled.

Subsequently, the division's remaining personnel were transferred to the regular prisoner of war camps in Germany.
