What are the top 5 greatest/largest most epic in scale battles/wars in all of ASOIAF history?

I’m really curious as someone who’s new to this universe/series I’ve been reading and delving into the books and lore of ASOIAF and I’ve been hooked on this universe. One thing that’s always really interested me is the battles/wars that take place in this universe. I’ve only read the first 3 books so my knowledge of this universe is still quite shallow but I was wondering what are the top 5 greatest/largest most epic in scale battles/wars in all of ASOIAF history? Which ones were the most important? They can take place anytime and anywhere during the timeline whether it was before the books or during the books, or whether it took place in Westeros or Essos. I’m really curious to hear some answers.
