The Battle of Kusonje was a two-day clash fought in the village of Kusonje near the town of Pakrac on 8–9 September 1991, during the Croatian War of Independence. The battle was initiated when a platoon of the Croatian National Guard (Croatian: Zbor narodne garde – ZNG) was ambushed by Croatian Serb forces while conducting a reconnaissance patrol. The ZNG deployed reinforcements to extract the ambushed platoon, but failed to reach them. The surviving members of the platoon held out until they ran out of ammunition and surrendered only to be killed by their captors and buried in a mass grave.
