The 1992 Yugoslav campaign in Bosnia was a series of engagements between the Yugoslav People's Army (JNA) and the Territorial Defence Force of the Republic of Bosnia and Herzegovina (TO BiH) and then the Army of the Republic of Bosnia and Herzegovina (ARBiH) during the Bosnian War. The campaign effectively started on 3 April and ended 19 May.
The war was part of the breakup of Yugoslavia. Following the Slovenian and Croatian secessions from the Socialist Federal Republic of Yugoslavia in 1991, the multi-ethnic Socialist Republic of Bosnia and Herzegovina – which was inhabited by mainly Muslim Bosniaks (44%), Orthodox Serbs (32.5%) and Catholic Croats (17%) – passed a referendum for independence on 29 February 1992. Political representatives of the Bosnian Serbs boycotted the referendum, and rejected its outcome. Anticipating the outcome of the referendum, the Assembly of the Serb People in Bosnia and Herzegovina adopted the Constitution of the Serbian Republic of Bosnia and Herzegovina on 28 February 1992. Following Bosnia and Herzegovina's declaration of independence (which gained international recognition) and following the withdrawal of Alija Izetbegović from the previously signed Cutileiro Plan (which proposed a division of Bosnia into ethnic cantons), the Bosnian Serbs, led by Radovan Karadžić and supported by the government of Slobodan Milošević and the Yugoslav People's Army (JNA), mobilised their forces inside Bosnia and Herzegovina in order to secure ethnic Serb territory. The war soon spread across the country, accompanied by ethnic cleansing.
The first clashes took place in Kupres between the Bosnian Croat Territorial Defence Force supported by the Croatian Army troops on one side and the Yugoslav People's Army. There were battles for Zvornik, Višegrad, Foča, Doboj, Prijedor and many more cities later. The JNA officially withdrew from Bosnia and Herzegovina in May 1992. In January 1992, a Bosnian Serb self-proclaimed statelet was declared. Later renamed Republika Srpska, it developed its own military as the JNA withdrew and handed over its weapons, equipment and 55,000 troops to the newly created Bosnian Serb army. On 20 May 1992 the JNA was formally dissolved, the remnants of which reformed into the military of the newly founded Federal Republic of Yugoslavia.
Background
Breakup of Yugoslavia
The war came about as a result of the breakup of the Socialist Federal Republic of Yugoslavia. A crisis emerged in Yugoslavia as a result of the weakening of the confederational system at the end of the Cold War. In Yugoslavia, the national communist party, the League of Communists of Yugoslavia, lost ideological potency. Meanwhile, ethnic nationalism experienced a renaissance in the 1980s after violence in Kosovo. While the goal of Serbian nationalists was the centralisation of Yugoslavia, other nationalities aspired to the decentralisation and further federalisation of the state.
Bosnia and Herzegovina, a former Ottoman province, has historically been a multi-ethnic state. According to the 1991 census, 44% of the population considered themselves Muslim (Bosniak), 33% Serb and 17% Croat, with 6% describing themselves as Yugoslav.
In March 1989, the crisis in Yugoslavia deepened after the adoption of amendments to the Serbian Constitution allowing the government of Serbia to dominate the provinces of Kosovo and Vojvodina. Until then, Kosovo and Vojvodina's decision-making was independent, and each autonomous province had a vote at the Yugoslav federal level. Serbia, under newly elected President Slobodan Milošević, gained control over three out of eight votes in the Yugoslav presidency. With additional votes from Montenegro, Serbia was thus able to heavily influence the decisions of the federal government. This situation led to objections from the other republics and calls for the reform of the Yugoslav Federation.
At the 14th Extraordinary Congress of the League of Communists of Yugoslavia, on 20 January 1990, the delegations of the republics could not agree on the main issues facing the Yugoslav federation. As a result, the Slovene and Croatian delegates left the Congress. The Slovene delegation, headed by Milan Kučan, demanded democratic changes and a looser federation, while the Serbian delegation, headed by Milošević, opposed it.
In the first multi-party election in Bosnia and Herzegovina, in November 1990, votes were cast largely according to ethnicity, leading to the success of the Bosniak Party of Democratic Action (SDA), the Serb Democratic Party (SDS), and the Croatian Democratic Union (HDZ BiH).
Parties divided power along ethnic lines so the President of the Presidency of the Socialist Republic of Bosnia and Herzegovina was a Bosniak, the president of the Parliament was a Serb, and the prime minister a Croat. Separatist nationalist parties attained power in other republics, including Croatia and Slovenia.
Beginning of the Yugoslav Wars
Meetings were held in early 1991 between the leaders of the six Yugoslav republics, and the two autonomous regions, to discuss the crisis. The Serbian leadership favoured a federal solution, whereas the Croatian and Slovenian leadership favoured an alliance of sovereign states. Bosnian leader Alija Izetbegović proposed an asymmetrical federation in February, where Slovenia and Croatia would maintain loose ties with the four remaining republics. Shortly after, he changed his position and opted for a sovereign Bosnia as a prerequisite for such a federation.
On 25 March, Franjo Tuđman and Serbian President Slobodan Milošević held a meeting in Karađorđevo. The meeting was controversial due to claims by some Yugoslav politicians the two presidents agreed to the partition of Bosnia and Herzegovina. On 6 June, Izetbegović and Macedonian president Kiro Gligorov proposed a weak confederation between Croatia, Slovenia, and a federation of the other four republics. That was rejected by the Milošević administration.
On 25 June 1991, Slovenia and Croatia declared independence. An armed conflict in Slovenia ensued, while clashes in areas of Croatia with substantial ethnic Serb populations escalated into a full-scale war. The Yugoslav People's Army (JNA) abandoned efforts to reassert control over Slovenia in July, while fighting in Croatia intensified until a ceasefire was agreed in January 1992. The JNA also attacked Croatia from Bosnia and Herzegovina.
In July 1991, representatives of the Serb Democratic Party (SDS), including SDS president Radovan Karadžić, Muhamed Filipović, and Adil Zulfikarpašić from the Muslim Bosniak Organisation (MBO), drafted an agreement known as the Zulfikarpašić–Karadžić agreement. This would leave SR Bosnia and Herzegovina in a state union with SR Serbia and SR Montenegro. The agreement was denounced by Croat political parties. Although initially welcoming the initiative, the Izetbegović administration later dismissed the agreement.
Between September and November 1991, the SDS organised the creation of six "Serb Autonomous Regions" (SAOs). This was in response to the Bosniaks' steps toward seceding from Yugoslavia. Similar steps were taken by the Bosnian Croats.
In August 1991, the European Economic Community hosted a conference in an attempt to prevent Bosnia and Herzegovina from sliding into war. On 25 September 1991, the United Nations Security Council passed Resolution 713, imposing an arms embargo on all former Yugoslav territories. The embargo had little effect on the JNA and Serb forces. Croatian forces had seized weaponry from the JNA during the Battle of the Barracks. The embargo had a significant impact in Bosnia and Herzegovina at the start of the Bosnian War. The Serb forces inherited the armaments and the equipment of the JNA, while the Croat and Bosniak forces obtained arms through Croatia in violation of the embargo.
On 19 September 1991, the JNA moved extra troops to the area around the city of Mostar. This was protested by the local government. On 20 September 1991, the JNA transferred troops to the front at Vukovar via the Višegrad region of northeastern Bosnia. In response, local Croats and Bosniaks set up barricades and machine-gun posts. They halted a column of 60 JNA tanks, but were dispersed by force the following day. More than 1,000 people had to flee the area. This action, nearly seven months before the start of the Bosnian War, caused the first casualties of the Yugoslav Wars in Bosnia. In the first days of October, the JNA attacked and leveled the Croat village of Ravno in eastern Herzegovina, on their way to attack Dubrovnik in southern Croatia.
On 6 October 1991, Bosnian president Alija Izetbegović gave a televised proclamation of neutrality, it included the statement "it is not our war". Izetbegović made a statement before the Bosnian parliament on 14 October with regard to the JNA: "Do not do anything against the Army. (...) the presence of the Army is a stabilizing factor to us, and we need that Army... Until now, we did not have problems with the Army, and we will not have problems later." Izetbegović had a testy exchange with Bosnian Serb leader Radovan Karadžić in parliament on that day. After Karadžić wagered that the Bosniak Muslims could not defend themselves if a state of war developed, Izetbegović observed that he found Karadžić's manner and speech offensive and it explained why the Bosniaks felt unwelcome, that his tone might explain why the others federated by Yugoslavia felt repelled, and that the threats of Karadžić were unworthy of the Serbian people.Tape record of the BiH Parliament, 88/3. – 89/2.

Throughout 1990, the RAM Plan was developed by SDB and a group of selected Serb officers of the Yugoslav People's Army (JNA) with the purpose of organizing Serbs outside Serbia, consolidating control of the fledgling SDS parties and the positioning of arms and ammunition. The plan was meant to prepare the framework for a third Yugoslavia in which all Serbs with their territories would live together in the same state.
Journalist Giuseppe Zaccaria summarised a meeting of Serb army officers in Belgrade in 1992, reporting they had adopted an explicit policy to target women and children as the vulnerable portion of the Muslim social structure. According to some sources, the RAM plan was crafted in the 1980s. Its existence was leaked by Ante Marković, the Prime Minister of Yugoslavia, an ethnic Croat from Bosnia and Herzegovina. The existence and possible implementation of it alarmed the Bosnian government.
Final political crisis On 15 October 1991, the parliament of the Socialist Republic of Bosnia and Herzegovina in Sarajevo passed a "Memorandum on the Sovereignty of Bosnia-Herzegovina" by a simple majority. The Memorandum was hotly contested by the Bosnian Serb members of parliament, arguing the Constitution required procedural safeguards and a two-thirds majority for such issues. The Memorandum was debated anyway, leading to a boycott of the parliament by the Bosnian Serbs, and the legislation was passed. The Serb political representatives proclaimed the Assembly of the Serb People of Bosnia and Herzegovina on 24 October 1991, declaring that the Serb people wished to remain in Yugoslavia. The Party of Democratic Action (SDA), led by Alija Izetbegović, was determined to pursue independence and was supported by Europe and the US The SDS made it clear that if independence was declared, Serbs would secede as it was their right to exercise self-determination.
