What difference did they make and what would have happened if they did nothing?
This group was able to help many Jews, deserters, and resistance groups find shelter and get supplies during the war. If they did nothing some Jews who escaped from camps would have instantly gotten caught by Nazis. Even though they didn't make as much of an impact as people like Irena Sendler and Oskar Schindler, they were able to save people and sing songs about the horrors that were going on. The awareness they gave probably caused others to help during the war.
