What are famous battles that utilized rocket artillery?

So after watching lots of WW2 movies (battle of the bulge or Patton) and documentaries. They never really captured the use of rocket artillery (calliope, katuysha, panzer werfen) in a battle. They have always glorified infantry or tanks. I have tried to look up info but the specific battles don't list what the artillery actually did. So what are some good sources to dig into this topic?
