Pandava conches and the war's omen

Chapter one is perhaps one of the hardest chapters in the Bhagavad Gita to understand. The first time you read it, you'll have questions like: Who is this person? Who is that person? Why is everyone blowing a conch shell? What's this guy's name again? And how is he related to this guy? And why does everyone's conch shell have a name?! We'll help break down the first part of Chapter 1 so all of this makes a little more sense!
