Napoleon keeps a diary detailing his rise to power on Animal Farm and increasing authoritarian rule. He recounts chasing Snowball from the farm and taking sole command. Though he adopts Snowball's idea to build a windmill, it is repeatedly destroyed by enemies. Napoleon orders the death of animals suspected of disloyalty. Over the years, the windmill is rebuilt but used for corn rather than power. Napoleon begins walking on two legs and taking on human habits, changing the farm's name to Manor Farm and forming an alliance with the neighboring farmer.
