Bosnia and Herzegovina on 8–11 October 1995. Its goal was to help the
Army of the Republic of Bosnia and Herzegovina (ARBiH) whose positions around the town of
Ključ, captured by them during
Operation Sana, were endangered by a counteroffensive by the
Army of Republika Srpska (VRS). The objectives of Operation Southern Move included the capture of the town of
Mrkonjić Grad and positions on the

. Finally, the offensive was also aimed at capturing the
Bočac Hydroelectric Power Station, the last significant source of electricity under VRS control in western Bosnia and Herzegovina. The combined HV and HVO forces were under the overall command of HV
Major General Ante Gotovina.
The offensive achieved its objectives, and significantly contributed, along with Operations Sana and
Maestral 2 to forcing the Bosnian Serb leadership to serious peace negotiations. The offensive also contributed to the displacement of 10,000 Bosnian Serb refugees and resulted in the deaths of at least 181 Serbs while hundreds more went missing following the operation. A country-wide ceasefire came into effect on 12 October, one day after the offensive ended, and was soon followed by negotiations which produced the
Dayton Agreement, ending the Bosnian War.
Background
As the
Yugoslav People's Army (''Jugoslovenska narodna armija'' – JNA) withdrew from Croatia following the acceptance and start of implementation of the
Vance plan
The Vance plan ( hr, Vanceov plan, sr, Vensov plan, italics=yes) was a peace plan negotiated by the former United States Secretary of State Cyrus Vance in November 1991 during the Croatian War of Independence. At that time, Vance was the ...
, its 55,000 officers and soldiers born in Bosnia and Herzegovina were transferred to a new
Bosnian Serb army, which was later renamed the
Army of Republika Srpska (''Vojska Republike Srpske'' – VRS). This re-organisation followed the declaration of the Serbian Republic of Bosnia and Herzegovina on 9 January 1992, ahead of the referendum on the independence of Bosnia and Herzegovina that took place between 29 February and 1 March 1992. This declaration would later be cited by the Bosnian Serbs as a pretext for the

. Bosnian Serbs began fortifying the capital,
Sarajevo, and other areas on 1 March 1992. On the following day, the first fatalities of the war were recorded in Sarajevo and
Doboj. In the final days of March, Bosnian Serb forces bombarded
Bosanski Brod with artillery, resulting in a cross-border operation by the
Croatian Army (''Hrvatska vojska'' – HV) 108th Brigade. On 4 April 1992, JNA artillery began shelling Sarajevo. There were other examples of the JNA directly supported the VRS, such as during the capture of
Zvornik in early April 1992, when the JNA provided artillery support from Serbia, firing across the
Drina River. At the same time, the JNA attempted to defuse the situation and arrange negotiations elsewhere in the country.
The JNA and the VRS in Bosnia and Herzegovina faced the
Army of the Republic of Bosnia and Herzegovina (''Armija Republike Bosne i Hercegovine'' – ARBiH) and the
Croatian Defence Council (''Hrvatsko vijeće obrane'' – HVO), reporting to the

that had been introduced in September 1991. By mid-May 1992, when those JNA units which had not been transferred to the VRS withdrew from Bosnia and Herzegovina to the newly declared
Federal Republic of Yugoslavia, the VRS controlled approximately 60 percent of Bosnia and Herzegovina. The extent of VRS control was extended to about 70 percent of the country by the end of 1992.
Prelude
By 1995, the ARBiH and the HVO had developed into better-organised forces employing comparably large numbers of artillery pieces and good defensive fortifications. The VRS was not capable of penetrating their defences even where its forces employed sound military tactics, for instance in the
Battle of Orašje in May and June 1995. After recapture of the bulk of the

(the

Operation Storm in August 1995, the HV shifted its focus to western Bosnia and Herzegovina. The shift was motivated by a desire to create a security zone along the Croatian border, establish Croatia as a regional power and gain favours with the West by forcing an end to the Bosnian War. The government of Bosnia and Herzegovina welcomed the move as it contributed to their goal of gaining control over western Bosnia and the city of
Banja Luka—the largest city in the Bosnian Serb-held territory.
In the final days of August 1995,
NATO launched
Operation Deliberate Force—an air campaign targeting the VRS. This campaign was launched in response to the
second Markale massacre of 28 August, which came on the heels of the
Srebrenica massacre. Airstrikes began on 30 August, initially targeting VRS air defences, and striking targets near Sarajevo. The campaign was briefly suspended on 1 September and its scope was expanded to target artillery and storage facilities around the city. The bombing resumed on 5 September, and its scope extended to VRS air defences near Banja Luka by 9 September as NATO had nearly exhausted its list of targets near Sarajevo. On 13 September, the Bosnian Serbs accepted NATO's demand for the establishment of an
exclusion zone around Sarajevo and the campaign ceased.
Following a relative lull in fighting in western Bosnia, the HV, HVO and ARBiH renewed their joint offensive against the VRS in the region. The HV and HVO component of the offensive,
codenamed
Operation Maestral 2, was launched on 8 September with the aim of capturing the towns of

. The
ARBiH 7th Corps advanced on the right flank of the HV and the HVO towards
Donji Vakuf. As Operation Maestral 2 neared its objectives, the
ARBiH 5th Corps launched
Operation Sana in the
Bihać area, aimed at pushing the VRS back to the
Sana River to the east. The ARBiH achieved significant territorial gains, advancing to capture the town of
Ključ, and approaching
Sanski Most and
Novi Grad by 18–19 September—before being halted by significant VRS reinforcements. A VRS counteroffensive, launched on the night of 23/24 September from Novi Grad, Sanski Most and
Mrkonjić Grad gradually pushed the 5th Corps back towards
Bosanska Krupa and Ključ, despite gradual arrival of reinforcements dispatched by the ARBiH 7th Corps. The VRS had approached within of Ključ by 6 October, and ARBiH control of the town was under threat. In response, the ARBiH requested HV and HVO assistance.
Order of battle
The HV and the HVO forces earmarked for the offensive comprised 11,000–12,000 troops, organised into two groups, under the overall command of HV
Major General Ante Gotovina. The primary group consisted of the
4th Guards and the
7th Guards Brigades, the
1st Croatian Guards Brigade

(''1. hrvatski gardijski zdrug'' – 1st HGZ) of the HV, while the second group was spearheaded by the 1st, 2nd and 3rd Guards Brigades of the HVO, and included the 126th Home Guard Regiment of the HV.
The VRS units facing the combined HV/HVO force were elements of Operational Group-2 and the 30th Division, under the command of
Colonel Milenko Lazić. They were deployed around Mrkonjić Grad, and comprised the 7th Motorised, 3rd Serbian and 11th Mrkonjić Light Infantry brigades. The three brigades, numbering approximately 5,500 troops, were tasked to cover the rear of the VRS force counterattacking the ARBiH force in Ključ.
Timeline

Operation Southern Move was to be carried out in two stages. The first stage involved the capture of Mrkonjić Grad and the surrounding Podrašnica Valley. In the second phase of the operation, the force would seize the last significant source of electricity in the VRS-controlled part of western Bosnia and Herzegovina—the
Bočac Hydroelectric Power Station. The whole operation was planned to take four days, immediately preceding a country-wide ceasefire scheduled to take effect on the morning of 12 October 1995. According to
Brigadier Ante Kotromanović, then commander of the 126th Home Guard Regiment, the offensive was approved by the United States, and U.S. warplanes attacked VRS positions near Banja Luka in preparation of the offensive.
Phase one: 8–9 October
The offensive began on 8 October with an attack launched by the HV 126th Home Guard Regiment and the HVO 1st Guards Brigade from a starting line west of Mrkonjić Grad, against positions held by the 11th Mrkonjić Light Infantry Brigade. This effort was intended as a diversion aimed at misleading the VRS defences regarding the main axis of the offensive. It was hampered by poor weather which prevented the effective use of artillery fire.
The main HV force committed to the offensive, comprising the 4th Guards and the 7th Guards brigades and the 1st HGZ, began their advance on 9 October. Poor weather and heavy fog forced the HV to postpone the attack from 6:00 until 8:50. The advance was supported by strong artillery
fire support and two
Mil Mi-24s of the
Croatian Air Force. The HV 7th Guards Brigade struggled to advance against the VRS positions southeast of Mrkonjić Grad around the villages of Liskovica, Bjelajci and Šehovci, manned by the 7th Motorised Brigade. The 4th Guards Brigade and the 1st HGZ faced the defences southwest of the town, manned by the 3rd Serbian Brigade. By the end of the day, the HV had advanced by about partially enveloping Mrkonjić Grad. The town itself was hit by about 200 artillery shells fired by the HV and HVO.
Phase two: 10–11 October
On 10 October, the 4th Guards Brigade broke through and outflanked the 7th Motorised Brigade positions, forcing the VRS to withdraw from Mrkonjić Grad. The move also placed the Podrašnica Valley and Čađavica junction under HV control, completing the objectives of the first stage of the operation. The HVO 2nd Guards Brigade was deployed on the right flank of the 7th Guards Brigade and the two units advanced north towards

mountain.
The HV units were replaced by HVO elements on 11 October. The HVO 1st Guards and 2nd Guards brigades took over the northward advance from the HV 4th Guards and 7th Guards brigades, while the HVO 3rd Guards Brigade relieved the 1st HGZ and the 126th Home Guard Regiment. The VRS defence was disorganised, and they were gradually pushed north, while maintaining effective artillery fire support for their retreating troops. By the end of the day, the HVO had captured the Bočac Hydroelectric Power Station. The final objective was achieved when the force reached a line south of Banja Luka. The advance reportedly came within of Banja Luka, whose electrical power supply was interrupted, and where a curfew was imposed in response to the deteriorating situation. Operation Southern Move ended on the night of 11/12 October.
Aftermath

The offensive captured an area wide and deep. The defeat of the VRS also made it clear to the Bosnian Serb leadership that they had to commit to ending the war through negotiations or risk the capture of Banja Luka. In addition, the offensive proved decisive in halting the VRS counteroffensive against the ARBiH near Ključ and Bosanska Krupa, and allowing the ARBiH to mount a successful advance against the VRS 1st Krajina Corps defending Sanski Most. Finally, the outcome of the battle brought the VRS to a position where it was forced to choose between defending Prijedor, Banja Luka or the Doboj–
Brčko route. This route had been vital for the resupply of both Banja Luka and Doboj since the VRS secured it in
Operation Corridor 92 three years earlier. According to a
Central Intelligence Agency analysis, the ground offensives of the HV, HVO and ARBiH in western Bosnia and Herzegovina, including Operation Southern Move, were a more significant contributor to bringing the Bosnian Serbs to the negotiation table than NATO airstrikes. A country-wide ceasefire went into effect on 12 October, followed by negotiations which produced the
Dayton Agreement on 21 November and ended the Bosnian War.
The offensive displaced 10,000 Serb refugees from Mrkonjić Grad, adding to a growing humanitarian crisis as another 30,000 Serbs fled Sanski Most before the ARBiH captured it in the final days of Operation Sana. Approximately 6,000 non-Serbs were forced to flee their homes in Prijedor and Novi Grad by Bosnian Serb forces. According to Bosnian Serb sources, 480 Serbs died or went missing in the fighting in the area of Mrkonjić Grad. The figure includes 181 bodies recovered in a
mass grave at the town's
Serbian Orthodox cemetery. According to the
Republika Srpska police who investigated the scene and interviewed witnesses, most of the dead were VRS
