The organisers expect an even more massive turnout at the traditional ceremony due to the high jubilee.

The Pohorje battalion was established on 11 September 1942 in Dobrovlje (N) in the Pohorje hills as a Partisan military unit. After conducting over 100 military operations, the battalion settled in a winter camp at Osankarica on 21 December 1942.

German troops discovered the camp at the beginning of January 1943 and on 8 January some 2,000 German soldiers attacked it, killing all 69 Slovenian soldiers. The Germans took 65 bodies and buried them in Graz, while the remaining four were uncovered later and taken to Slovenia.
