Conduct of Operations and Results: As the numerically superior Axis forces closed on Jajce, the Partisan command decided to destroy the war-essential carbide factory and other infrastructure in Jajce and withdraw its forces before they were surrounded. The town was retaken on 4 October and there were few casualties on either side. See Operation “Jajce II” for the combined losses during both operations.
