Operational History

Feb 42: commenced search and destroy operations between Petrinja and Glina against formations of the Partisan Banija Detachment, clearing and burning down the villages of Šušnjar, Martinović, Gradac, Drenovac and several others. Toward the end of March the Banija Detachment launched a series of counterattacks on the garrisons at Maja and Grabovac, forcing the Croatians to bring in elements of the 11th Infantry Rgt. as reinforcements which, together with the Petrinja Brigade, by 12 April had driven the Partisans out of the Banija for the time being.
Jun 42: at the beginning of June, the Brigade supported the Croatian 1st Mountain Division during the second sweep through the Banija, but there was little enemy resistance.

10 Sep 43: I and II Bn. transferred to Banja Luka and began offensive operations southwest of the city on 12 September when they encountered and engaged elements of the 1st Krajina NOU Brigade. In the course of heavy fighting, II Bn. was severely mauled on 14 September with an estimated 100 killed and wounded, 100 missing and 109 taken prisoner along with many weapons.
30 Sep – 9 Oct 42: I Bn. and what was left of II Bn. took part in Operation “Manjača-Gebirge” to the southwest of Banja Luka.
