In Chapter 9 of "Animal Farm", how is the devotion of Clover and Benjamin to Boxer displayed?
When Boxer's hoof was split, Clover "treated the hoof with poulices of herbs which she prepared by chewing them, and both she and Benjamin urged Boxer to work less hard". Boxer, however, was determined "to see the windmill well under way before he reached the age for retirement", and refused to take a rest. After his hoof was healed, Boxer "worked harder than ever", pushing himself past the point of exhaustion. Clover and Benjamin again "warned him to take care of his health", but to no avail.
Finally, one day, Boxer collapsed while trying to "drag a load of stone down to the windmill" alone, and when the other animals went to go get help, Clover remained with Boxer, and Benjamin "lay down at Boxer's side and, without speaking, kept the flies off him with his tail". When Boxer had recovered enough to limp back to his stall, Clover and Benjamin "prepared a good bed of straw for him". Clover tenderly administered the medicine sent by the pigs for Boxer, and "in the evenings she lay in his stall and talked to him, while Benjamin kept the flies off him". They were not there when the van came to take Boxer away, but as soon as he realized what was happening, Benjamin came galloping as fast as he could to tell the other animals, and Clover, forcing her way to the front of the crowd, made a desperate but vain attempt to warn Boxer to try to escape, because the sign on the van identified it as belonging to the "Horse Slaughterer" (Chapter 9).
