There's a lot more information about her group on this page. They seem to have had a surprisingly large impact even during WWII, in Germany and internationally.
p.s. The 2005 German movie Sophie Scholl: The Final Days is about the group's last 6 days.

"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize." Sorry, I should've used a more objective phrase than "surprisingly large". I meant, I would have expected the group would have been crushed and noone heard about them around Germany during the war, let alone overseas, when instead, well, reading those two pages I was surprised, and gratified, by the impact they had, during WWII in Germany and around the world, and ever since. What else could my comment mean?!

"Of course" is never a helpful phrase I think, except for patting oneself on the back. What is this, Peep Show?! I can't help hearing that in David Mitchell's voice. e.g. https://www.youtube.com/watch?v=ApslS7RKxYA
