The Battle

The Battle was the biggest battle ever and ended (or so the UNOP thought) the Outsiders forever. It wasn't the battle that killed the most (that's the Blockhead Battle).
The Battle started when the main army of the Outsiders realized that the defenses of Peanutsville was weak since most of the army went with The UNOP Front they attacked Peanutsville which had only two great generals to protect it. They first started to search for all secret passageways built by Violet and started to siege. Luckily almost all passageways were blocked or heavily guarded so the Outsiders who had 2,000  Blockhead bombs ( 2,000 times more than they had in the Blockhead Battle) couldn't get in. The generals of Violet and Shermy who were the only great generals in the city tries to wear out the other army until help arrived since every time they pushed out the invaders they had to go back in due to Blockhead bombs. Violet started to use traps to slowly destroy the invaders but eventually the Outsiders broke through the outer wall. The next day The UNOP Front led by Luci and Shroe prepare their supplies and plans to relieve the forces protecting Peanutsville. Then the Charlie Brownan army attacks the Outsiders and are able to trap them in a small part of the outskirts before being forced to retreat by the bombs. Then Luci and Shroe start attacking the walls and all men are drafted. Eventually  Luci and Shroe got through the walls and basically destroyed the Outsiders army until, I'm not telling yet.
Now for why Chuck proposed to Chucketa. So when he was sent to war he had to bring supplies to the main forces and when he was doing that he was shot and almost killed. After he recovered he proposed to Chucketa since he realized that life is short.
