Croatian Counteroffensive
In order to prevent JNA's attempt to cut off Slavonia, and to stop the expulsions from western Slavonia, the Croatian troops undertook their first offensive operation of this scale during the homeland war.
The military aim of Otkos 10 was to secure the Bilogora hills and to capture favourable positions for further advance towards Papuk mountains to the southeast thus securing land communication between Slavonia and the rest of Croatia.
Croatian troops involved included: 151st brigade (Samobor), 127th brigade (Virovitica), 57th battalion and National defense detachment (Grubišno Polje), 24th mixed artillery battalion, 52nd battalion (Daruvar), a T-55 tank platoon of 105th brigade (Bjelovar), 19th mixed antitank artillery battalion (Virovitica), special police forces from Bjelovar, and a Križevci volunteer company.
