Atticus was accused of raping Mayella. Mayella said Tom Robinson was helping her with a chore and he came up from behind her and punched her on her right eye but Tom says “ My left hand is useless sir”.

Tom has helped her out before but they hadn't had any problems.
They try to accuse Tom of raping Mayella because in their time most people were racist. Atticus
