My grandfather lost a sister to a partisan attack. These were people who kept on working in factories or workshops in occupied territory. While some resistance commanders tried to minimize victims among civilians (also because if you lost the population support, they would rat them out in exchange of food or just out of spite/vengeance), for others any man/woman employed in an activity which could indirectly support the German war machine was fair game, even if they didn't have a choice on the matter. War is a dirty affair indeed.
