What other events can be compared to Mrs.Dubose's courage in To Kill a Mockingbird?

Several characters had their own moments of courage. Boo Radley
had two. First, he covered Scout and Jem with a blanket during the fire at Miss Maudie's. Then,
he saved Jem and Scout from Bob Ewell's attack. Mr. Avery, disreputable as he was, saved much of
Miss Maudie's furniture and helped fight the fire. Calpurnia took two white children to an all
black church service. Atticus, himself, had an unusual moment which gave his children a source of
pride. When he shot the rabid dog, the children realized that their father was not as old and
dull as they had thought. Atticus was not one for showing off his shooting skills, but this time
he did to save the community.
