Operational History

(see III Ustasha Brigade for additional information)

Dec 41: Battalion HQ in Kostajnica. As will be seen below, this Ustasha battalion was smaller than most of the others and was used mainly to garrison Kostajnica and to guard nearby railway lines, bridges and other key infrastructure. It does not seem to have been used operationally very often or to have had much contact with the enemy (the Partisans).
