What happens to Miss Maudie's house in 'To Kill A Mockingbird'?

Probably due to the Great War. Miss Maudie is a childhood friend of Uncle Jack. Uncle Jack is Atticus' younger brother so, in 1933, Uncle Jack and Miss Maudie were about 40 - 45 years of age. The U.S entered the Great War in 1917 - 16 years before the time of this novel. Miss Maudie may have been 24-29 years of age and so too her husband. When we encounter Miss Maudie in chapter 5 she attacks nut grass in her yard like the Second Battle of Marne fought in 1918. Is this reference coincidental?
