Well, themes in this novel may include change. The war would have brought a lot of changes to farm life. For example, there could be new regulations on farming to support the war effort. Also, family is likely a theme. Families on farms had to deal with the absence of men who went to war and the added responsibilities at home.
It might show the shortage of resources. For example, lack of manpower as men went to war, and scarcity of materials like machinery parts.
Food shortages were a big challenge. The boy might have had to deal with rationing, not having enough to eat like before the war. Also, the constant fear of air raids. Every time the sirens went off, he had to rush to the shelters.
One of the main themes is power and corruption. The pigs, especially Napoleon, gradually gain more and more power and become corrupt. Another theme is the abuse of language for control. The pigs manipulate language to justify their actions and mislead the other animals. Also, there is the theme of the failure of utopian ideals. The initial vision of an equal animal society quickly deteriorates into a dictatorship.
Survival is likely a theme too. Working on a farm has its own difficulties, and for black characters, they may have to fight against both natural hardships and social inequalities to survive. For example, they might have to deal with unfair land distribution or discrimination in getting resources for farming.
One of the main themes is power and corruption. The pigs, especially Napoleon, gradually gain more and more power and become corrupt, just like the human oppressors they once fought against.
Well, in Animal Farm the novel, there are themes like inequality. At first, the animals fight for equality but in the end, there is a new form of hierarchy with the pigs on top. The theme of false hope is also there. The animals hope for a better life after the revolution, but things go wrong. And there's the theme of totalitarianism. Napoleon rules with an iron fist, suppressing any opposition.
Power dynamics is a key theme. We see how power shifts from Mr. Jones to the pigs. Social inequality is another theme. Despite the initial idea of equality, the animals end up with different levels of privilege. And the theme of revolution and its aftermath. The animals' revolution against Mr. Jones doesn't lead to the utopia they expected but rather a new form of oppression.
Well, I know a story. A boy in England during WW2 was called Jack. Jack's town was often under air raids. He and his friends formed a small group to help the air raid wardens. They would run around and make sure people were in the shelters. Jack once found a stray dog during an air raid. He took it in and it became his loyal companion throughout the war. He also collected scrap metal for the war effort.
One main theme is likely to be sacrifice. The red poppy is often associated with the sacrifice of soldiers in WW2, and the novel would probably explore this through the characters' stories.
One main event was the sharing of food. Soldiers from different sides would exchange things like chocolate or biscuits. Another was the singing of Christmas carols together, creating a strange but beautiful harmony in the midst of war. Also, there were some cases of soldiers simply chatting and getting to know a bit about each other's lives away from the battlefield.
