After the Major's inspiring speech, the more intelligent animals, especially the pigs, realize that they should prepare for the Rebellion. Then, after Mr. Jones, who has fallen into drink, passes out and forgets to feed the animals one evening and "they could stand it no longer." One of the cows breaks through the store-shed and the animals help themselves to the feed. This activity wakes Mr. Jones, who comes out with his four hired hands; they lash out at the animals with whips, but the animals turn upon thei men, causing their tormentors to flee in fright.
After the humans run down the road the animals have effectively revolted:
the Rebellion had been successfully carried through: Jones was expelled, and the Manor Farm was theirs.
With the removal of the humans, the animals destroy the ribbons, trappings of human clothing, that Molly wears, as well as the others that hang in the barn. In the morning, the animals revel in their freedom; in their excitement they "gambolled round and round, they hurled themselves into the air." However, when they return at night, the animals expect to partake of some of the milk taken from the swollen udders of the untended cows but they are not given any by the pigs, indications are that all animals are not equal, after all.
This early chapter points to Orwell's disappointment in socialist governments. As a Socialist himself Orwell grew disturbed by such dictatorships as that of Stalin; in short, he became disappointed that Socialist governements did not remain truly socialist.
