Can you help me find literary devices in this excerpt from Animal Farm?

"Comrades!" cried Squealer, making little nervous skips, "a most terrible thing has been discovered. Snowball has sold himself to Frederick of Pinchfield Farm, who is even now plotting to attack us and take our farm away from us! Snowball is to act as his guide when the attack begins. But there is worse than that. We had thought that Snowball's rebellion was caused simply by his vanity and ambition. But we were wrong, comrades. Do you know what the real reason was? Snowball was in league with Jones from the very start! He was Jones's secret agent all the time. It has all been proved by documents which he left behind him and which we have only just discovered. To my mind this explains a great deal, comrades. Did we not see for ourselves how he attempted–fortunately without success–to get us defeated and destroyed at the Battle of the Cowshed?"

The animals were stupefied. This was a wickedness far outdoing Snowball's destruction of the windmill. But it was some minutes before they could fully take it in. They all remembered, or thought they remembered, how they had seen Snowball charging ahead of them at the Battle of the Cowshed, how he had rallied and encouraged them at every turn, and how he had not paused for an instant even when the pellets from Jones's gun had wounded his back. At first it was a little difficult to see how this fitted in with his being on Jones's side. Even Boxer, who seldom asked questions, was puzzled. He lay down, tucked his fore hoofs beneath him, shut his eyes, and with a hard effort managed to formulate his thoughts.

"I do not believe that," he said. "Snowball fought bravely at the Battle of the Cowshed. I saw him myself. Did we not give him 'Animal Hero, first Class,' immediately afterwards?"

"That was our mistake, comrade. For we know now–it is all written down in the secret documents that we have found–that in reality he was trying to lure us to our doom."

"But he was wounded," said Boxer. "We all saw him running with blood."

"That was part of the arrangement!" cried Squealer. "Jones's shot only grazed him. I could show you this in his own writing, if you were able to read it. The plot was for Snowball, at the critical moment, to give the signal for flight and leave the field to the enemy. And he very nearly succeeded–I will even say, comrades, he would have succeeded if it had not been for our heroic Leader, Comrade Napoleon. Do you not remember how, just at the moment when Jones and his men had got inside the yard, Snowball suddenly turned and fled, and many animals followed him? And do you not remember, too, that it was just at that moment, when panic was spreading and all seemed lost, that Comrade Napoleon sprang forward with a cry of 'Death to Humanity!' and sank his teeth in Jones's leg? Surely you remember that, comrades?" exclaimed Squealer, frisking from side to side.

Now when Squealer described the scene so graphically, it seemed to the animals that they did remember it. At any rate, they remembered that at the critical moment of the battle Snowball had turned to flee. But Boxer was still a little uneasy.

"I do not believe that Snowball was a traitor at the beginning," he said finally. "What he has done since is different. But I believe that at the Battle of the Cowshed he was a good comrade."

"Our Leader, Comrade Napoleon," announced Squealer, speaking very slowly and firmly, "has stated categorically–categorically, comrade–that Snowball was Jones's agent from the very beginning–yes, and from long before the Rebellion was ever thought of."

"Ah, that is different!" said Boxer. "If Comrade Napoleon says it, it must be right."

"That is the true spirit, comrade!" cried Squealer, but it was noticed he cast a very ugly look at Boxer with his little twinkling eyes. He turned to go, then paused and added impressively: "I warn every animal on this farm to keep his eyes very wide open. For we have reason to think that some of Snowball's secret agents are lurking among us at this moment! "
