The Battle of the Cowshed, which occurs in Chapter 4 of Animal Farm, is the point at which the experiment at Animal Farm seems most likely to survive. Having already driven off Jones in the initial revolution, they now defeat Jones and two other farmers, Mr. Pilkington and Mr. Frederick, that join him in an effort to retake Animal Farm. Beyond this significance, the episode is also important in that it sees Snowball emerge as a true revolutionary hero. He is the one that plots and orchestrates the animals' defense, and he and Boxer are awarded the title of Animal Hero, First Class. But after the battle, Snowball has a falling out with Napoleon over the construction of the windmill, which he supports, and is driven from the farm by Napoleon's dogs. After this event, the Battle of the Cowshed becomes significant as an example of how Napoleon and Squealer manipulate information. Snowball's role in the battle is written out, and at one point in the story, Squealer tells the animals that Snowball actually assisted the humans in the assault on the farm. He predicts after Snowball's expulsion that "the time will come when we shall find that Snowball’s part in it was much exaggerated," and due to his considerable skill as a propagandist, this prediction comes true.
