Since the collapse of Italy there has been a daily increase in partisan activity in the area around the Istria Peninsula. These partisan groups had established strong, and in some cases fortified, positions all around the peninsula. They tended not to attack but hold their positions stubbornly and had recently intensified their artillery fire along the mountain and coastal roads. The reinforced Kampfgruppe SS-Panzer-Grenadier-Regiment 1 Leibstandarte Adolf Hitler was moved to northeastern Italy along the border with Yugoslavia in preparation to launch a rapid three-phase operation, with the objective to sweep clean the Istria peninsula of partisans.
