Why Was Rašica on Fire in 1941?

In September 1941, the village of Rašica was set on fire as retribution for the partisan attack in which six passengers had been killed in a black Horch with car registration number IA-24080. The Archives of the Republic of Slovenia keeps the original report about the incident written by the German criminal police in Bled on September 22, 1941. Enclosed to the report are sketches of the scene of the crime where the attack took place and eight rather self-explanatory photos.
