More scapegoating at Snowball's expense. Boxer seems, amazingly, to remember history the way that it occurred, but Squealer quickly convinces him that his memory is faulty.
At a meeting, several animals confess to having been in league with Snowball, or with Jones, or both. (We think the teeth-baring dogs might have had something to do with the confession.)
After they confess, Napoleon… has them killed.
Uh-oh. This Revolution is going downhill fast.
And then, due to Boxer's doubt regarding the new and rewritten history, Napoleon tries (and fails) to have him killed by the dogs.
There's a lot of subtlety here—none of the animals, and especially not Boxer, think for a moment that Napoleon actually ordered the attack. On the surface, it just looks like the dogs went rogue and attacked him.
But some of the animals have picked up on the fact that things aren't quite working out.
Clover looks over the farm and thinks to herself that these scenes of bloody terror are certainly not what the animals have worked so hard for.
The final straw? "Beasts of England" is abolished.
