At dawn on August 5, 1995, over 130,000 Croatian troops and police launched a coordinated artillery and infantry assault on the Knin region. Code-named Operation Storm, the action targeted the capital of the Republic of Serbian Krajina, a breakaway statelet occupying nearly a third of Croatia since 1991. The bombardment was one of the largest in Europe since World War II. By midday, Croatian flags flew over Knin’s medieval fortress. Serbian military and political leaders, along with tens of thousands of civilians, had already fled east into Bosnia. The ground war in Croatia was effectively over.
The offensive mattered because it decisively altered the military map of the Balkans. In 84 hours, the Croatian Army reclaimed over 10,000 square kilometers of territory. The rapid collapse of Serbian Krajina demonstrated the shifting balance of power, directly enabling NATO airstrikes against Bosnian Serb forces weeks later and paving the way for the Dayton Peace Agreement. For Croatia, it was a moment of national vindication and military triumph.
International perception often focuses solely on the celebratory parades in Zagreb. This overlooks the operation’s severe human cost. The UN and international tribunals later documented that the offensive involved widespread crimes against the remaining Serb civilian population, including killings and the systematic burning of homes. Over 200,000 Serbs became refugees. The event thus exists in a dual state: a foundational victory for modern Croatia and a source of lasting trauma and displacement for its Serb minority. The political and demographic contours of the region were permanently reset that day.
