The Bosnian War and the siege
How Srebrenica became an enclave under attack.
The war in Bosnia and Herzegovina (1992–1995) followed the breakup of Yugoslavia. After Bosnia and Herzegovina declared independence, Bosnian Serb political and military leadership sought to create an ethnically homogeneous territory through force. Cities and towns were shelled; civilians were murdered, detained, raped, and expelled in campaigns the ICTY later characterised as ethnic cleansing and, in Srebrenica, as genocide.
Eastern Bosnia, including the Drina valley, was among the most violently contested regions. By mid-1992, Srebrenica was cut off from Bosnian government-held territory. Displaced people from surrounding villages fled into the town, swelling its population far beyond capacity. Hunger, disease, and continuous military pressure defined life in the enclave long before July 1995.
Local ABiH forces under Naser Orić conducted raids from the enclave; the VRS maintained the siege. International attention focused intermittently on the humanitarian catastrophe, culminating in the designation of Srebrenica as a United Nations “safe area.”
A safe area in name only
Resolution 819, UNPROFOR, and the limits of protection.
On 16 April 1993, United Nations Security Council Resolution 819 demanded that all parties treat Srebrenica and its surroundings as a safe area “which should be free from any armed attack or any other hostile act.” Further resolutions extended the concept to other cities and authorised UNPROFOR to deter attacks. The promise of safety became a central fact of life—and of later betrayal—for the people of the enclave.
A Dutch battalion of UNPROFOR, known as Dutchbat, was deployed to implement the safe-area regime. Its main base occupied the former battery factory complex in Potočari, several kilometres north of Srebrenica town. Observation posts ringed the enclave. Dutchbat was lightly equipped relative to the surrounding VRS forces, and air support depended on a chain of political and military authorisations that proved slow and inadequate when the final attack came.
By early 1995 the enclave was exhausted. Aid convoys were blocked or stripped. When the VRS launched its offensive in July, neither the “safe area” designation nor the presence of UN peacekeepers prevented the fall of Srebrenica or the crimes that followed. The ICTY has held that the subsequent mass murder of the men and boys of Srebrenica constituted genocide.
War begins in Bosnia and Herzegovina
Following Bosnia and Herzegovina’s independence referendum and international recognition, armed conflict erupts. Bosnian Serb forces of the Army of Republika Srpska (VRS), backed by elements of the Yugoslav People’s Army, seize large parts of the country. Systematic campaigns of ethnic cleansing target Bosniak and Croat civilians.
Siege of Srebrenica begins
Srebrenica, a predominantly Bosniak town in eastern Bosnia, is encircled by VRS forces. Surrounding villages fall; tens of thousands of displaced civilians crowd into the shrinking enclave. Shelling, sniping, and severe shortages of food, medicine, and water become constant.
UN Security Council Resolution 819
The United Nations Security Council adopts Resolution 819, demanding that all parties treat Srebrenica and its surroundings as a “safe area” free from armed attack and any other hostile act. The resolution calls for the immediate withdrawal of Bosnian Serb paramilitary units and for unimpeded humanitarian access.
Further “safe areas” and UNPROFOR
Resolutions 824 and 836 expand the “safe area” concept to Sarajevo, Tuzla, Žepa, Goražde, and Bihać, and authorize UNPROFOR to deter attacks. In practice the areas remain under siege; the force is lightly armed and dependent on consent from the parties.
Dutchbat in Srebrenica
A Dutch battalion of UNPROFOR (Dutchbat) is deployed to the Srebrenica safe area, headquartered at the former battery factory in Potočari. The enclave remains overcrowded and cut off. Humanitarian conditions deteriorate; VRS restrictions on aid and movement continue. Dutchbat’s mandate and resources prove insufficient to defend the civilian population if a full-scale assault occurs.
Enclave under mounting pressure
The VRS tightens the siege. Outlying observation posts are threatened. Food and fuel shortages worsen. In the wider war, the strategic balance shifts; VRS command under General Ratko Mladić prepares operations against the eastern enclaves.
The UN failed Srebrenica
Findings of the Secretary-General’s 1999 report (A/54/549).
The United Nations’ own inquiry—the Report of the Secretary-General pursuant to General Assembly resolution 53/35, The fall of Srebrenica (A/54/549, 15 November 1999)—states plainly that the international community failed the people it had promised to protect. The “safe area” was left demilitarized and undefended in any meaningful sense: Bosniak defenders were disarmed under the safe-area regime, while the Army of Republika Srpska (VRS) retained heavy weapons and freedom of manoeuvre around the enclave.
When the VRS assault began in July 1995, Dutchbat was outgunned and stood aside. Requests for close air support were denied, delayed, or arrived too late to alter the outcome. The report documents a chain of hesitation, misjudgement, and institutional failure at every level—from the enclave to UNPROFOR command to Member States. VRS forces advancing into Srebrenica met no effective resistance from the United Nations.
Secretary-General Kofi Annan presented the report with a formal admission of responsibility. The tragedy of Srebrenica, he wrote, was “replete with lessons for the United Nations and its Member States,” and would “haunt our history forever.” That admission does not restore the dead. It records, in the UN’s own words, that the promise of a safe area was broken while more than eight thousand men and boys were murdered.
“The tragedy of Srebrenica will haunt our history forever.”
Day by day: the fall and the genocide
From the assault on the enclave through the mass executions and the concealment of bodies in secondary graves. Descriptions reflect ICTY trial findings.

Between 6 and 16 July 1995, the Army of Republika Srpska overran the Srebrenica enclave, expelled the women and children, and systematically murdered more than 8,000 Bosniak men and boys. The ICTY Appeals Chamber in Prosecutor v. Krstić (2004) confirmed that genocide was committed. Subsequent judgments against senior political and military leaders—including Radovan Karadžić and Ratko Mladić—reaffirmed those findings.
What follows is a chronological account of those eleven days and of the later reburial of victims intended to hide the crime.
Attack on the enclave begins
VRS forces of the Drina Corps open a coordinated offensive against the Srebrenica safe area. Shelling intensifies on the southern perimeter. UN observation posts come under fire. Civilians flee deeper into the enclave toward the town and Potočari.
Southern perimeter collapses
Bosnian Serb forces capture key terrain and overrun several UN observation posts. Dutchbat personnel are detained or forced to withdraw. Attempts to obtain close air support are delayed and limited. Panic spreads as refugees stream north toward Srebrenica town and the UN compound at Potočari.
Enclave shrinks; mass displacement
The VRS advances steadily. Tens of thousands of civilians abandon villages and gather in Srebrenica town and around the Dutchbat base in Potočari. Conditions are chaotic: little food or water, continuous shelling, and collapsing local defence. Dutchbat’s ability to protect the population is effectively broken.
Fall of Srebrenica
Srebrenica town falls to the VRS. General Ratko Mladić enters the town and is filmed touring it with officers and camera crews. Thousands of civilians flee to the UN compound in Potočari; others, predominantly military-age men and boys, form a large column intending to break out through the woods toward free territory near Tuzla. The “safe area” has ceased to exist.
Potočari: separation of men and boys
At the UN base and surrounding factories in Potočari, VRS soldiers separate men and boys (generally from approximately 16 years of age) from women, children, and the elderly. The separated males are detained; many are later bused to execution sites. Women and children are forcibly deported by bus toward Bosnian government-held territory. ICTY judgments establish that this separation was a deliberate step in a plan to destroy the Bosniak population of Srebrenica.
The column through the woods
An estimated 10,000 to 15,000 men—members of the Army of the Republic of Bosnia and Herzegovina (ABiH) 28th Division and civilian men and boys—attempt to escape through forested terrain toward Tuzla. The column is ambushed, shelled, and repeatedly attacked. Thousands are killed in combat, captured, or later executed after surrender. Survivors who reach free territory become key witnesses.
Mass detentions and first large-scale killings
Detained men from Potočari and captured members of the column are held in schools, warehouses, and other buildings across the region—including Bratunac and nearby villages. On or about 13 July, hundreds are murdered at the Kravica warehouse and at other sites. Buses continue deporting women and children while the male population is systematically eliminated.
Organised mass executions
ICTY evidence documents large-scale, organised executions at multiple locations. Men held overnight are transported to killing sites including fields near Orahovac (Lažete), the Petkovci dam area, and other locations. Victims are often blindfolded, bound, and shot in groups. Bulldozers and earth-moving equipment are used to bury bodies in primary mass graves.
Final mass executions
Executions continue at Branjevo Military Farm, the Pilica (Kula) Cultural Centre, Kozluk, and other sites. By 16 July the bulk of the mass killing of detained Srebrenica men and boys has been carried out. ICTY trials—including those of Radislav Krstić, Vujadin Popović and others, Ratko Mladić, and Radovan Karadžić—establish that these crimes were committed with genocidal intent.
Primary mass graves
Bodies are buried in primary mass graves near the execution sites. Forensic and ICTY investigations later link these graves to the July killings through soil, clothing, ligatures, blindfolds, shell casings, and DNA identification of victims.
Secondary graves and concealment
In an organised effort to conceal the crimes, primary graves are exhumed and remains reburied in numerous secondary mass graves across eastern Bosnia. Bodies are disarticulated and scattered across multiple sites—complicating recovery and identification for decades. International investigators and, later, the International Commission on Missing Persons (ICMP) work to reconnect remains and identify victims through DNA.
After the killings
Primary mass graves near execution sites were later disturbed. Remains were removed and reinterred in secondary graves across the region—an organised cover-up documented extensively at the ICTY. DNA-led identification by the ICMP and partners has since reunited scattered remains; over 6,700 victims have been identified and buried at the Potočari Memorial Center. The search for those still missing continues.
ICTY finding
“By seeking to eliminate a part of the Bosnian Muslims, the Bosnian Serb forces committed genocide. They targeted for extinction the forty thousand Bosnian Muslims living in Srebrenica, a group which was emblematic of the Bosnian Muslims in general.”
