Squealer plays an important part in maintaing Napoleon’s power and keeping the other animals under control. He keeps turn situations into Napoleon’s favour. There is a lot of examples of this in Animal Farm by George Orwell.
In the beginning of the book, we meet Squealer, who is an excellent speaker, as the one who together with Snowball and Napoleon work out the theory of “Animalism”.
The first example of Squealer’s importance we can find at the end of chapter three. The milk, which mysterious had disappeared, was given to the pigs, and so was the ripened apples. Some of the other animals murmured to each other, but it was no use. All the pigs were in full agreement on this point. This is the point where Napoleon and Snowball had to use Squealer’s oratorical gifts. He had to convince the others about that the pigs were brainworkers and needed all the vitamins they could get. He explained to them that Mr. Jones would come back if they didn’t get all the food they could get. Now the goal was reached, because no one wanted Mr. Jones back. When it was put them into this light, they had no more to say. This is just one of the proofs that tell us that Squealer has great persuasive powers, and I think that it is in this situation that Napoleon realise that Squealer may be an important part of his further plans.
