The Proud Rebel (1958)

Confederate veteran John Chandler (Alan Ladd) returns from defeat in war to find his home razed, his wife dead and his young son, David (David Ladd), traumatized and rendered mute. Desperate to cure the boy, Chandler takes David to a small town in Illinois where he hopes to find a doctor. But, soon after the pair arrives, Chandler finds himself framed for assault -- and forced to choose between serving hard time and working for struggling local farmer Linnett Moore (Olivia de Havilland).
