The Battle of the Barracks (Croatian: Bitka za vojarne) was a series of engagements that occurred in mid-to-late 1991 between the Croatian National Guard (ZNG, later renamed the Croatian Army) and the Croatian police on one side and the Yugoslav People's Army (JNA) on the other. The battle took place around numerous JNA posts in Croatia, starting when Croatian forces blockaded the JNA barracks, weapons storage depots and other facilities. It formally began on 14 September; its objective was to neutralise the JNA positions in ZNG-held territory and to secure arms and ammunition supplies for the poorly equipped ZNG.
The Battle of the Barracks was an escalation of the conflict between Croatian authorities and the Croatian Serbs who openly revolted in August 1990 and the JNA's efforts to preserve the Yugoslav federation. At the same time, Croatia made moves towards achieving independence from Yugoslavia. The Battle of the Barracks briefly preceded the start of the JNA's campaign in Croatia—itself amended in early September to add relief of the blockaded barracks to the operation plans. However, the JNA's advance was largely curbed by the ZNG and it relieved few JNA facilities.
The ZNG and the police captured small, isolated JNA posts, and a number of large weapons depots and barracks—including the entire 32nd (Varaždin) Corps of the JNA. The move provided the Croatian forces with a sizable stock of weapons—including 250 tanks, hundreds of artillery pieces and a large supply of small arms and ammunition—which proved crucial in defending against JNA advances in the early stage of the Croatian War of Independence. Some of the JNA facilities surrendered without fighting, while others put up armed resistance to the takeover. In some places, this caused civilian casualties because the barracks were situated in urban areas. Legal charges of abuse of or killing captured JNA personnel, and charges of war crimes against civilian populations were filed in Croatia, but most defendants remain at large.
In November, the JNA and Croatia reached several agreements to end the blockade and withdraw JNA from Croatia. The pullout was completed by 4 January 1992, except in areas around Dubrovnik and on the islands of Vis and Lastovo. The JNA maintained its presence there until the summer of 1992. As the JNA withdrew from the areas it controlled in Croatia, it was replaced by the UN peacekeepers agreed upon by the Vance plan.
