The ceasefire of 3 January allowed implementation of the Vance plan, which provided for the protection of civilians in specific areas designated as UN Protected Areas (UNPAs) and deployment of UN peacekeepers in Croatia. One of the UNPAs defined by the plan, UNPA Western Slavonia, encompassed parts of the municipalities of Novska and Nova Gradiška, as well as the entire municipalities of Daruvar, Grubišno Polje and Pakrac. Thus the UNPA covered the area held by the JNA on 3 January, additional territory to the north, recaptured by the HV in late 1991, and towns which never came under SAO Western Slavonia control—such as Grubišno Polje and Daruvar. The peacekeeping force named United Nations Protection Force (UNPROFOR), initially expected to be 10,000-strong, started to deploy on 8 March.
