The Uprising of District 8 was the first uprising in Panem. Katniss learned of the uprising during a television propo in Mayor Undersee's office that she was not meant to view. This event resulted in the subsequent bombing of District 8. The uprising had been planned for some time and was inspired by Katniss' "stunt" with the berries. The Capitol was completely prepared and at their stations when Katniss came for the Victory Tour, but the bombing didn't happen until much later. The rebels were winning, until the Capitol sent reinforcements, an army of Peacekeepers and a hovercraft. Twill said it took less than 2 days to return the city to the Capitol's control.
When Katniss and Peeta visited District 8 for the Victory Tour, the citizens of 8 had a "dress rehearsal" for the uprising; everyone went to their planned positions that would attempt to take over in the real uprising. Then, the night Peeta proposed to Katniss, they took the opportunity to begin the uprising. According to Bonnie and Twill, because they were expected to watch the engagement show in large groups late that night, it was not apparent to the Peacekeepers what was happening until it began. It is mentioned that the loud machinery in the factories of District 8 allowed these plans to be passed easily from rebel to rebel at work when the peacekeepers or possible recorders could not hear them.
