At the beginning of chapter 5, things do appear to be going quite well for the animals. They have defeated Jones at the Battle of the Cowshed so are feeling empowered. Even this victory though will prove an issue as attempts are made, by the end of this chapter, to discredit Snowball:
we shall find that Snowball’s part....was much exaggerated.
The disputes between Snowball and Napoleon are intensifying and a power struggle is obvious:
it is the windmill, the modernization and industrialization of Animal Farm, that brings their conflict to a head.
This makes the sheep uncertain and they are already being influenced by Napoleon and they chant the now familiar
Four legs good, two legs bad
This does not bode well for Snowball as he is constantly interrupted by them. The animals are also deeply divided over the windmill which Snowball wants and Napoleon is seriously opposed to - although ultimately, Napoleon will support and even claim the usefulness of having the windmill but for reasons completely different from Snowball's.
Good leaders would not scare the masses or argue in front of them. Napoleon takes it to the extreme when he then chases Snowball off the farm using brute force - the dogs!
The animals are confused but Squealer is able to offer them comfort as he convinces the animals that the pigs will take on the responsibility of running the farm to prevent the others from making
Their forced leadership is soon entrenched as Boxer says:
Napoleon is always right
The pigs have already introduced a state where the animals are scared and confused and Napoleon is only looking out for himself.
