News of the uprising reached Himmler, who ordered additional armed police battalions to suppress the uprising, and the German authorities also shot 37 Slovene prisoners, mostly Partisans and Partisan supporters, at their Gestapo headquarters in Begunje na Gorenjskem. The Germans attacked the Cankar Battalion at Pasja Ravan, where the Partisans resisted for three days, killing dozens of armed police. Knowing the Germans were sending reinforcements, the Cankar Battalion decided to retreat from Pasja Ravan and, after discussing a number of alternatives, decided to retreat to Dražgoše.
