The word enemy is described as ‘one that attacks or tries to harm another"
George Orwell's enemies are Burmese people and also the British Empire as he was a subdivisional police officer and he had to follow the Britsh Raj command while the Burmese didnt like him because he was also the part of those people who took over there country.
While in all this Mr Orwell and the Burmese had new mutual enemy which is the elephant, the elephant tried to ruin the Bamboo houses even he killed a coolie who was innocent. George Orwell had to save the place though he hate the people as well but he was left with no choice.So he went off and shoot the elephant.
