Strategic Narrative Overview
Bosnian Croat TO forces made limited gains on 4–5 April within Kupres town, but JNA armour advanced to the outskirts on 6 April and entered the town on 7 April. Croatian forces were hampered by poor command structures, weak coordination, and a lack of heavy weapons. The decisive breakthrough came when a JNA armoured battalion was deployed from Knin, enabling Serb-JNA forces to drive Croatian units from the plateau entirely by 11 April.
01 / The Origins
As Bosnia and Herzegovina descended into war in early 1992, the Kupres Plateau became a flashpoint due to its value as a major north-south supply route. Bosnian Croat and Bosnian Serb communities each held positions around local settlements, while the JNA began moving reinforcements into the area from 5 March. Negotiations to prevent armed conflict failed on 2 April, and the battle commenced the following day amid ethnic tensions and competing territorial ambitions.
03 / The Outcome
The battle ended in a JNA and Bosnian Serb victory, establishing lines of control across the Kupres Plateau that remained static until 1994, when the HVO recaptured the area. The fighting produced over 200 combat deaths. Legal consequences followed decades later: Republika Srpska charged seven Croats with wartime atrocities in 2012, and Croatian authorities charged 21 former JNA members with war crimes against HVO prisoners in 2013.
