The undertakingís objective was the destruction of an undetermined partisan group in the mountains around Cardaci, some 7.5 miles (12 km) to the north-east of Bugojno. The German force comprised elements of Generalleutnant Emil Zellnerís 373rd Division (kroatisch), but the nature of any Croat contribution (if any) is unknown. At this time strong partisan forces were moving through the area toward the road linking Konjić and Sarajevo road. The area was surrounded by the 373rd Division on 5 July, but the following sweep located no partisans and there were no casualties.
