The children, Scout and Jem, intervened and approached the mob at the jail where Atticus was guarding Tom Robinson. Scout's innocent conversation with Mr. Cunningham, one of the mob members, and her recognition of other men in the mob led them to disperse and retreat. Her presence humanized the situation and prevented any violence from occurring.
Scout recognized Mr. Cunningham in the mob and engaged him in conversation about his son, which humanized Atticus in Mr. Cunningham's eyes and helped diffuse the situation. This act of empathy and understanding ultimately led to the mob dispersing and Atticus being saved.

Atticus explains the concept of a mob to his children by describing it as a group of people who act emotionally and without thinking rationally.

In "To Kill a Mockingbird", the mob is after Atticus because they want to harm Tom Robinson, a black man falsely accused of raping a white woman. The mob wants to take matters into their own hands and deliver their own form of justice, even if it means going against the legal process and putting Atticus in danger for defending Tom.
In chapter 15, the children find Atticus outside the Maycomb jail. He is sitting in front of the jailhouse door reading a book, keeping watch over Tom Robinson to protect him from a possible lynch mob.
To protect tom from the mob!
They found him at the courthouse in town. Tom Robinson had been moved there to await trial, and Atticus was afraid there would be trouble from the people who lived in Maycomb. He's right, as a mob shows up at the jail to come after Tom Robinson, which the children see, as they were there looking for Atticus.
