Minor sabotage

A minor sabotage (aka little sabotage or small sabotage; Polish: mały sabotaż) during World War II in Nazi-occupied Poland (1939–45) was any underground resistance operation that involved a disruptive but relatively minor and non-violent form of defiance, such as the painting of graffiti, the manufacture of fake documents, the disrupting of German propaganda campaigns, and the like. Minor-sabotage operations often involved elements of humor.

The purpose of minor-sabotage operations was primarily psychological — to show Polish civilians that the resistance remained active, and thus bolster civilian morale, and to wear down the German occupier.
