Casualties Twelve Croatian policemen were killed and 21 injured in the ambush. The two captured policemen were ferried across the Danube and transported to
Novi Sad, but were released and returned to Osijek by the evening of 2 May. Vojislav Milić, a paramilitary from
Valjevo, was the only fatality among the Serb militia. Four other paramilitaries were wounded. Some of the police killed at Borovo Selo were found to have been mutilated, their ears cut, their eyes gouged out and their throats slit. These acts were meant to inflame ethnic hatred.
Escalation to war The clash led Tuđman's advisers to advocate an immediate declaration of independence from Yugoslavia and retaliation against the JNA, which Croats viewed as being pro-Serb. On 3 May, Tuđman opined that Croatia and Serbia were virtually at war, but said he hoped the international community would stop the violence. According to the Croatian historian Davor Marijan, Tuđman's decision not to retaliate against the JNA was often interpreted at the time as cowardice bordering treason, leading to public criticism and the resignation of General
Martin Špegelj from the post of defence minister. Nonetheless, the decision afforded Croatia much-needed time to prepare for war, as
Yugoslav Navy Fleet Admiral
Branko Mamula later acknowledged. The incident shocked the Croatian public, causing a massive shift in public opinion towards demonisation of Serbs, supported by the
Croatian media. Serbs were collectively labelled "
Chetniks", "terrorists" and "enemies of Croatia". Similarly, Serbs referred to Croats as "
Ustaše" and "enemies of the Serb people". Thus, a political settlement to avoid all-out war became increasingly unlikely. After the clash, war appeared unavoidable. On 8–9 May, the
Presidency of Yugoslavia convened to discuss the events in Borovo Selo and deliberate over a JNA request for military intervention. The presidents of all of Yugoslavia's
constituent republics were present at the meeting. The Croatian leadership permitted the JNA to be deployed to areas where inter-ethnic tensions were running high. On 9 May, representatives of the
federal and
Croatian governments visited Vukovar. Federal representatives visited Borovo Selo, unlike the Croatian government officials who stated they "refused to talk to terrorists". In response to the Borovo Selo clash, the JNA redeployed a part of the 12th Proletarian Mechanised Brigade from Osijek and the 1st Mechanised Battalion of the 453rd Mechanised Brigade based in
Sremska Mitrovica to the Vukovar area. At the same time, the 2nd Mechanised Battalion of the 36th Mechanised Brigade was moved from
Subotica to Vinkovci. Despite the deployment of the JNA in the area, ethnically motivated skirmishes persisted until the start of the
Battle of Vukovar in late August.
Memorial controversy and prosecution During the 1996–98
United Nations administration established pursuant to the
Erdut Agreement to restore the area to Croatian control, three Croatian non-governmental organisations erected a memorial on public property at the entrance to Borovo Selo, but the site was quickly vandalised. A new monument was erected in the centre of the village in 2002, but this was also vandalised soon after completion. A new plaque bearing the names of the 12 Croatian policemen killed in the incident was added to the monument in 2012, but was also subject to vandalism. Although the vandalism was condemned by local Serb politicians, they complained that the memorial was offensive to the Serb minority and imposed guilt on the entire community because it branded Serb forces at Borovo Selo in 1991 as "Serb terrorists". In February 2012, an Osijek court convicted Milan Marinković of
war crimes and sentenced him to three-and-a-half years in prison for mistreating two captured Croatian police officers. In 2014, Marinković's sentence was reduced to three years on appeal. Four other men were indicted in relation to the officers' mistreatment. Since they live outside Croatia, they are not subject to prosecution by the Croatian judiciary. ==Footnotes==
