Strategic Narrative Overview

The ARBiH launched Operation Autumn-94 on 20 October, targeting Donji Vakuf with a secondary thrust toward Kupres. When the primary advance stalled, reinforcements shifted focus to Kupres. On 29 October the HVO, judging the plateau strategically threatened, independently launched Operation Cincar on 1 November. Following a brief halt in ARBiH operations and a direct appeal from President Izetbegović, the two forces coordinated for the first time, combining their offensives against VRS defences.

01 / The Origins

The battle arose from the broader Bosnian War context following the Washington Agreement of March 1994, which ended the Croat–Bosniak War and created a formal alliance between the ARBiH and the HVO against the Army of Republika Srpska. The Kupres plateau held strategic value as a VRS-controlled terrain feature threatening supply routes and flanking positions. Both the ARBiH and HVO initially pursued separate operations to exploit VRS vulnerabilities in the area.

03 / The Outcome

HVO forces captured Kupres on 3 November 1994, concluding the battle with a joint ARBiH–HVO victory. The territorial gains secured the right flank for the subsequent Croatian Army and HVO Operation Winter '94, launched in late November to relieve the siege of Bihać. The battle demonstrated that the Washington Agreement alliance could function operationally, shaping the strategic direction of the wider war.
