Strategic Narrative Overview
The VRS launched its offensive on 24 June 1992, retaking Derventa and pushing HVO and HV forces northward while capturing several towns. In a second phase, VRS units advanced to the Sava River, the border with Croatia, and eliminated an HV and HVO bridgehead at Bosanski Brod. The operation involved over 60,000 troops and proceeded in coordinated phases, ultimately dislodging Croatian and Bosnian Croat forces from the Bosanska Posavina region.
01 / The Origins
During the Bosnian War, the Army of Republika Srpska faced a critical strategic problem when HV and HVO forces captured Derventa, severing the sole overland road connecting Banja Luka in western Bosnia to eastern Bosnian Serb territories. This blockage threatened the cohesion of Serb-controlled areas and prompted the VRS to plan a large-scale offensive to restore the corridor through the Bosanska Posavina region of northern Bosnia and Herzegovina.
03 / The Outcome
By 6 October 1992, the VRS had secured the corridor and expelled HV and HVO forces from Bosanska Posavina. A Croatian National Defence Council report attributed the defeat to internal conflicts, a dual chain of command, and poor counterintelligence. Speculation arose that the outcome reflected a political land-trade arrangement between Serb and Croatian leaderships, though a CIA analysis rejected those allegations.
