Here's a breakdown of the major events that lead to the fighting:
* Chapter 1: The Games are announced and Katniss and Peeta are chosen as tributes. This sets the stage for the conflict.
* Chapter 13: Katniss realizes the Capitol's true intentions and the rebellion is starting to form.
* Chapter 16: The uprising begins in District 8, marking the start of the open conflict.
* Chapter 18: The Quarter Quell games begin, where the fighting is more explicit and violent.
So, while there's no single page where the fighting "starts," Chapter 18 is where the full-scale conflict truly erupts within the Games.
