The rebellion itself is a moment of triumph, and the animals are stunned at how quickly it happens. They overthrow Jones and his men with relatively little bloodshed, and quickly implement some of the tenets of Animalism. They enjoy a bountiful harvest and life is unquestionably better for the animals soon after the rebellion. The negative side of the rebellion is that its leaders quickly seek to corrupt its principles to their own ends. The culmination of this is when Napoleon and the other pigs become indistinguishable from the humans at the end of the book. The process begins, however, very soon after the rebellion itself, when the pigs keep the milk from the cows for themselves in contrast with the teachings of Animalism.
