In October 1993, hardline HVO commander
Ivica Rajić arrived in Vareš from
Kiseljak via Bosnian Serb-held territory. Shortly thereafter, he assumed de facto control of the enclave, removed the existing municipal leadership, and installed allies from outside the area. Reports indicate that Bosniak civilians were harassed, robbed, and driven from their homes, prompting a large-scale flight southward. Meanwhile, the ARBiH concentrated forces around the enclave. On 19 October, ARBiH units attacked
Ratanj, followed by the capture of the Croat-majority village of Kopjari on 21 October, which further escalated tensions. == Stupni Do massacre ==
