Although the last and most important of the Seven Commandments of Animal Farm declared that "all animals are equal," such was not the case. The pigs soon set themselves apart from the others, first absconding with the daily milk to mix with their mash. The pigs do no work, instead supervising the labor of the other animals. They learn to read and take over the harness room as their headquarters. Napoleon takes nine puppies, and they soon grow into his ferocious enforcers. When work on the windmill begins, all of the animals are forced to endure on reduced rations--except the pigs. The work week grows longer for the non-pigs, while the pigs soon move into the farmhouse and begin sleeping on beds. The hens are forced into giving up their eggs, which they consider murder. Another commandment is broken when the pigs order the death sentence for any animals suspected of having collaborated with the unseen Snowball. The animals are forced to address Napoleon as "our Leader, Comrade Napoleon." Soon, the pigs discover Mr. Jones' stash of whisky, which they consume until drunk.
When the pig population grows, the other animals recognize that Napoleon, the only boar on the farm, must be the sire. Boxer, instead of receiving his overdue retirement, is sold to the horse slaughterer--perhaps the greatest indignity to occur on Animal Farm. In the final chapter, the pigs exert their power by walking upright on two legs as they prepare to join forces with the humans, and once again the farm returns to its original name, "Manor Farm."
