http://hr.wikipedia.org/wiki/Bitka_za_Vukovar
Bitka za Vukovar je najveća i najkrvavija bitka u Domovinskom ratu. To je bila 87-dnevna opsada hrvatskog grada Vukovara od strane Jugoslavenske narodne armije, uz pomoć srpskih paravojnih snaga od kolovoza do studenog 1991. godine tijekom Domovinskog rata. Bitka je završena porazom lokalnog Zbora narodne garde, velikim razaranjem Vukovara i brojnim ubojstvima i progonom hrvatskog stanovništva.

Iako je bitka bila značajan i simbolički gubitak za Hrvatsku, koja nije povratila kontrolu nad gradom do 1998. godine, to je, također, bila pobjeda, koja je koštala JNA i pomogla da Hrvatska dobije međunarodnu potporu za svoju neovisnost. Budući da je široko štovana kao ključni trenutak u tijeku Domovinskog rata, to je pirova pobjeda Jugoslavenske narodne armije nad hrvatskim braniteljima Vukovara.

The Battle of Vukovar (Croatian, Serbian: Bitka za Vukovar) was an 87-day siege of the Croatian city of Vukovar by the Yugoslav People's Army (JNA), supported by various Serbian paramilitary forces, between August-November 1991 during the Croatian War of Independence. It ended with the defeat of the local Croatian National Guard, the near-total destruction of Vukovar and the murder or expulsion of most of the Croat population of the city and surroundings.

Although the battle was a significant and symbolic loss for Croatia, which did not regain control of the town until 1998, it was also a very costly victory for the JNA and helped to gain international support for Croatian independence. As such, it is widely regarded as having been a crucial turning point in the course of the war (less info)
