Boxer fights in the Battle of the Cowshed and the Battle of the Windmill, but is upset when he thinks he has killed a stable boy when, in fact, he had only stunned him. this shows that he is gentle in nature, even when dealing with an enemy. When Boxer defends Snowball 's reputation from Squealer 's revisionism , the pigs designate him as a target for the Great Purge , but he easily out muscles the dog executioners, sparing them at Napoleon's request. His death shows how far the pigs are willing to go. When he collapses from overwork, the pigs say they have sent him to a veterinarian , when they actually have sent him to the knacker 's yard to be slaughtered, in exchange for money to buy a case of whiskey for the pigs to enjoy.
